- Dr Booth conducts a scientific experiment to decide whether E10 petrol really damages the fuel systems on our bikes. Read the juicy stats/results here ➡️ www.44teeth.com/e10-fuel-vs-e...
We've had E10 in north America for years. The main issue is that ethanol absorbs water. Especially in a carburetor, this means that E10 will turn into goop within weeks to months as it evaporates. Bad news for winter storage
The main issue is the fuck off great big vehicles that do more gallons to the mile than miles to the gallon!
@@steven-vn9ui The higher the ethanol, the lower the calorific value of the fuel. Some vehicles will used 10% more fuel, and others will suffer long term damage.
@@steven-vn9ui Why you mad, bro?
I’ve used E10 for my outboard for years. No problems at all.
@@davidmatthews3093 I wonder whether the very large increases in the costs of fuel, or the rationing we can expect very soon, are things that suggest fuels which are less economical, and can damage fuel system parts of older vehicles, are something we need to strongly support?
I'm a fan of the channel, but as an engineer I can only shake my head at this video.
Using a scale with precision of 1g is ridiculous in this instance, using off the shelf o-rings is absolutely not representative and using a piece of aluminium welding rod (usually 4043 aluminium) is also not representative at all of all the different kinds of aluminium used in an engine. I personally also don't see a reason to distrust manufacturers in rating their own vehicles suitable or unsuitable for the use of e10 since they know the exact type of material used for every single part. This test was honestly incomplete at best and misleading at worst. Also there are so many more things to the discussion of e10. For example: e10 is less energy dense (about 2%) and therefore will lead to less power in vehicles that are designed for e5, but more power in vehicles that are designed for e10. This will also lead to higher consumption when using e10, which is offset by the cheaper price tho. Additionally in some cases e10 will reduce engine knock.
As a rule of thumbs for motorcycles: If it's fuel injected, it is probably modern enough to be used with e10, if it's carbed you are probably better off with e5, but looking up the manufacturers recommendation is always a good idea.
Yamaha set a cut off date of 1991. Like they had a crystal ball in 1991 and all of a sudden 1992 was impervious to this fuel that nobody had even thought of at the time...utter bollocks of course.
Hence why this clip ended up on Bike Sausage.
@@philclarke7712 They actually say that bikes from 1990 are fine, probably because at some point in the 80s they switched to ethanol proof fuel systems because the world started using e5 fuels and some smart guy at Yamaha predicted that the amount of ethanol in fuels will only increase in the future.
Awesome breakdown, thanks for a real heads up! Cheers

Couldn't agree more Blockbuster2033. This is sausage in other words crap. Using a set of caliper to measure o-rings is the funniest thing I've seen today, but it's still early and I haven't watched the latest Del video yet, so there's competition.
These fools should have used carbs as their baseline material. There is also specific tools to measure o rings, simple calipers and micrometers aren't those tools.
I've run a few tanks of E10 in my MT10. I averaged about 105m a tank compared to 127m with E5 so I go with the full fat.
Ethanol contains less energy compared to Unleaded Fuel.
Same here, only I'm running a 20 year old car. Being a Toyota, it will run on E10, but I find I get around 10% better fuel economy from E5/Super, which negates the price difference. Seems to run better, too, probably because ethanol gives less energy.
I've also dropped about 20miles range. Definitely worth a couple of quid extra for 20miles back.
127 miles a tank wow
Same here on my Ducati runs a lot better on e5
E10 is the Governments way to make you ditch your old vehicles and buy milk floats. The same way Apple turns your older iPhone Into a brick with software updates.
Communist bustards
Based on this comment… i can tell you’re not a millionaire 😂
It definitely does make a difference. E10 was giving my bimmer atrocious mpg, switched over to E5 and the engine is smoother, more mpg and it's only around 6p more/L for E5 so for a full tank it's less than a fiver extra.
2004 Corsa 1400cc automatic. Only 63,000 miles. Wife’s car used for shopping trips. Works great, MoT pass every year. With that sort of use it doesn’t do great on fuel, usually 30mpg. Filled with e10 petrol and got 24mpg. Twenty percent reduction. Back to e5 for as long as it’s available as it works out cheaper per mile.
I agree. E5 is better.
Considering how much more it gives it roughly comes to the same price
@KkKk-px2le Possibly, however when I was using supermarket fuel on my bimmer the fuel tank breather (purge) valve went. The BMW specialist advised me to always use branded fuel in bimmers and showed me a piece of someone's engine that was knackered from supermarket fuel.
@@seanglossop4777what’s the difference between Asda fuel ?
One of things I’ve noticed is poorer fuel economy. I still drive in the same steady economical way but cannot achieve the mpg I was getting on my one and half year old car before.
I have a 19 year old 1.6. Mini Cooper. According to the gov website, my car was compatible with E10. I used the E10 fuel and my car started running ... rough? Not like a diesel, but it was definitely noticeable and my mpg was ridiculous. My car also started to cough on start up. So decided to try the E5. My car no longer coughs or runs rough and my mpg has increased massively. I’ve gone from filling up twice a week at minimum to once a week/week and a half. I will not go back to E10.
I've had starting issues, power loss and significant mileage drop when e10 is used on both my 2018 v strom 1000 and the brand new 1290 SAS. No issues with e5 at all. I will stick with E5 until its time to sell or exchange. Even when I have to use e10, I always add a fuel stabiliser in the tank.
Yes, it does make a difference in my Honda CG125. Poor starting in cold weather, poorer mileage. Went back to e5.
Plastic tanks on Ducatis, Aprilias etc have had problems with E5 already… it is well published about the tank swelling problems.
E10? Or E5?!
@@bikesausage2614 E10. E5 on pumps is in quite a lot of cases actually E0, there is no Ethanol in it at all. This depends on the brand. Thousands of owners of Gen1 Aprilias with plastic fuel tanks, including myself, have the swelling issue. I have to drain it over the winter and store the tank dry in a warm place and it will actually shrink back, otherwise i have to fight it to get it mounted. Ask Griff at AP workshops and he will 100% confirm this.
Yup, my RSV Mille has a belly more swollen than Jockey Wilson
@@theavangelist There’s an image 😳
Glad my Ducati has metal tank only 6yr old
Having ridden to Scotland and back twice over the last couple months, the difference from E10 to E5 is significant.
On E10 there is less power and my bike is sluggish and vibrates a lot more and the engine feels lumpy and lower MPG and over range is less.
On E5 within a few mins the engine performance improves significantly, more responsive and more power, no vibrations and the engine runs smoother and better MPG and range
Every time I've used e10 in my 4 stroke enduro bike it has flat spots in the rpm and the odd splutter from the carb. Also I've noticed it makes the inside of the carb bowl and jets go green after a few weeks standing,
Bye bye personal transport.
That's the plan people time to wake up.
Who told you to sell your horse?
cracked up at the random shot of the girls at the pump. very informative experiment, appreciate it, often wondered how much of a difference e10 makes to components
Can you do an MPG experiment too? I swear I get less miles with E10....
Hi Boothy, do you know what material your ‘O’ ring was made from? There are many types; EPDM, Nitrile, Polychloroprene, Silicone, Butyl, Viton etc. Not all types of rubber would be resistant to gasoline irrespective of whether there is ethanol in the fuel or not and would be subject to swell.
It sure does. E10 gives my car misfires in multiple cylinders and loads of fault codes and the E10 makes your car lame. E5 is the way to go.
What material was your rubber oring made from? A material suitable for fuel systems?
Essso synergy has 0 ethanol (in the south) even though its marked e5 if your bothered
Didn’t know that!
@@stillshakin2125 you're not aloud nice things up north.
Same in the Netherlands and Belgium. For now all the E5 fuels are 0%. In the E10’s it’s close to 10% tho…
I have notice fuel economy drop when using e10. I always go for branded petrol e10 or supermarket e5.
Good effort. If you ever redo this experiment, for precision sake I suggest using a scale that shows 2, 3 or 4 decimal points. Rather than just by the gram. Especially since the experiment timeframe was only 2 months.
Remember kids, the difference between science and screwing arround is writing if down

Top vid squire! Good luck on the island 👍
Fuel economy on my F Type went from c.14mpg to 12mpg around town with E10.
So I really don't believe that E10 is "better for the environment" as you burn more of it.
Not better for the Enviroment, not better for your wallet, not better for the engine, but cheaper to produce and therefore much better for the fuel companies.
😭😭😭 12mpg, not sure different type of fuel is gonna have an effect on the environment regardless if your mpg is that low
I second your data and post. I've had a V8 S type jag for a few years now and it always averaged 21mpg. I'm now getting 19.
Thought there was also issues with higher water content in the fuel due to the bioethanol that can mess up carbs and tanks.
On a dyno you drop 5% power on e10 fuel. I’ve tried it on the 3 bikes I own same result each time. The bikes are Triumph 850 sport(2020), triumph t100 (2017) with Tec cam fitted and Enfield 500 Trails (2019) fitted with Hitchcock 615cc conversion.
Everything runs 99 ron in my house, even the bush trimmer
I have an lawnmower dat recommends e10 is it good to use for lawnmowers?
dont you have to richen your AFR with E10 to make the most power? eg 12.5 instead of the usual 13.0 for most machines?
What oring material were you using !
My first question is ... Was the O-ring being used one of a type that would communally be used in a fuel system or Carb, or was it just a run of the mill O-ring. My next question is what would happen if you re-did the experiment but this time got a new o-ring say a new injector seal from a modem car then a new replacement o-ring from a carb system. Are the new o-rings in new vehicles any better set up to deal with the ethanol or are manufactures just telling us they are. Like your work, really interesting video. :)
On earlier vehicles, rubber parts in the fuel system were invariably nitrile rubber. This will cope with intermittent contact with efuels, but will fail relatively quickly when continually immersed.
Plastic and metal fuel tanks can also suffer damage as a result of efuels.
Both my car and my bike both ran like shit on E10…idles like shit and took longer to turn over. All the evidence I need.
Wouldn't use e10 to light the bbq😂😂😂😂😂👍🕯️🕯️
I’ve noticed a 50 mile + pepped up performance when using esso 99 conspared to supermarket e10 And that’s on a bogo standard 2006 mondy 1.8 16v
Yep same here Reg E10 vs E5 Supper on a 1.6t Tuscon 2016. 50 to 60 extra miles and better performance. E10 had time when at roundabouts it just did not go had to rev very hard, almost dangerous. My hyundai dealers has a notice saying E10 is fine but use E5 super every now and then to clean things up.
E10 has been the only fuel for decades in California, no problem with that apart from being hygroscopic. Which basically means if you put your bike away for a long time, make sure the tank is completely full so the air gap it can absorb water from is smallest.
Even my old (1997) carbed DR650 had no problem with it. The swelling tank problems (Ducati?) were solved in the early 2000's and were mainly caused by the water that was absorbed by the ethanol, which in turn would be absorbed by the tank material.
Don't forget that most fuel systems come from the same companies that supply the car industry as well....
Don't worry about E10 too much, we've been the guinea pigs over here in the good old US of A since 1990...
Agreed - '86 K75, '99F650, "01 KLR, "20 DR and various small engines. No problems, always stored with full tanks and SeaFoam.
I live in the states and ya know what? Fk ALL that ethanol loaded fuel, it's shit.
I run E10 in my daily bike, an '02 Deauville 650. Honda say it's rated for it and despite what the doom-mongers said, it's perfectly happy on it, the bike is for workhorsing and commuting, so the power loss is not a problem. And no my fuel system has not rotted out, everything I've read suggests E10 causes most of the problems when it's left for long periods, so not a problem for me when the bike uses a tank every one to two weeks .
What HAS left me rather annoyed is the drop in fuel economy. I ran it on bogo petrol before the introduction of E10, so it's actually a fair comparison. The bike was hitting 55-60mpg per tank, depending on what I've been doing and how fast I'd been doing it, and is now doing 50-55mpg, with it generally towards the low 50's which leads me to question if E10 does actually make a difference. At times my full-to-reserve mileage has been as low as 160 miles, where previously it would comfortably hit 200miles, sometimes a lot more, for the same amount of fuel, and the bike is pretty well maintained, and probably actually in a better state now than before E10 was introduced.
I'd genuinely love to see some test measuring if the lower mpg figures E10 gives over old bogo E5 is made up for by the lower emissions of E10, because I'm not convinced it does at this point and it's a bit of fallacy to tick the 'green' box.
Same here on my bandit 600 daily bike
So a 20% loss in mpg and you're still using the stuff? I would never put E10 in my bike.
I left 1/4 tank of E10 in my '06 hornet (carbs) from start of October to start of march as I was suffering with a bad back. When I came to start the bike it would only run on 2 cylinders. After diagnosis of misfire I stripped the carbs to find blocked jets and emulsion tubes. I now only run E5 super from quality forecourts
check and see if the vacuum petcock is working correctly. cuz if it dribbles with the bike not running it makes running carbs super difficult. i got an 99 bandit 12 that run on American e10 for most of its miles and its fine. stored for 6 months out of the year and no issues.
@@nick4506 I notice that a lot of people in the states say that they've never had a problem with E10 whereas it seems that a lot of people in the uk have. Could it be possible that the difference in the climate affects it? Or maybe the petrol you guys have is a different grade?
@@sambrooks7862 i don't think it's climate cuz the us has literally every climate you want. i think we just got e10 earlier and our petroleum engineers have had time to get it right. and now all the good ethonal gas formulas are patented here in the us. just gotta wait for your manufacturers to buck up and pay licensing or come up with something else. just a thought.
but people complain every time there is a change, attributing every problem to that. and it takes a while for people to realize that it really didn't change that mutch.
also stuff like stabil and most other fuel stabilizer additives are just ethonol and dye, and people swear by those. they complain about ethanol then say they fixed it by adding more ethanol. so I don't think it's as bad as people say it is.
@@nick4506 food for thought? Thanks for taking the time to reply Nick.
@@sambrooks7862 also in the law the e10 in us, the 10% is a maximum for regular and it can vary a lot, sometimes when corn is expensive its like 2-6% out of the nosle. but idk how the law is in britten, could be that that's the floor instead of the ceiling sout it could be 10+ given what ever the market conditions for corn are.
i know in britten and the eu the oil part is expensive so maybe more incentive to max out the ethanol.
also for our e10 it's on top of whats already allowed to boot octane, so sometimes supreme or the highest octane fuel you can get here is like 25% ethanol. and most bikes use this stuff so idk what the issues people are haveing with e10 in britten.
Yeees, tried exchanging o-ring for a fuel tap, sealed for two days on the e10. I would never use e10 fuel on any carb bike. At least not let it stand for a while, without topping up with e5 or any other low alc content fuel. Good luck on the island!
There are people who run E85.
@@dirtygarageguy and very high boost pressures.! lol.!
Thanks for your reassurance on E5. My car is of the age that needs E5, I am told, and it came as a shock to me last year to have to use E10 on many occasions when touring UK as many fuel stations have blithely switched ALL their pumps, except the expensive stuff, to E10 and 'sod the customer'. So where I could not get the old E5 and had to use E10 and worried about its effect on my old car. West Scotland has so far not been affected by the switch and the Highlands and islands still get E5, good on them. and with a tank range of 400+miles, I can be choosy. (a bit like having to arrange uplifts/recharging points were I daft enough to use an EV without the hours wait).
Happily I live in a country where our government has banned E10 so most of the year I can operate happily without worry.
So if you want to flush out your tanks of the new poison take a trip to the Isle of Man which has more going for it than a certain bike festival.
I'm running a 27 year old RF900 on E10, the manual says it can run E10 but is bracketed USA only as nowhere else in the world had it at the time it was printed (1993). Fuel lines were changed recently simply because they were old & I didn't fancy setting fire to the old girl, plus the fuel tap was taken apart to check it's OEM rubber internals condition for cracks or hardening before switching to the E10. I also fitted a 4degree ignition advancer the week after E10 became available, a common RF fix/ cure for known poor low end response which predates the new fuels introduction & it helped massively from tick over to 4k revs. It now runs great, no extra engine temp & a whole lot better than before! That is because the carbs actually needed more than a good clean, a proper setting up & vacuum leaks seen too, from when I bought it and thus it ran awful on E5, so I can't really judge economy before and after fairly. I'm happy to keep using the E10, but it's a 52 week a year ride & never gets put away or stored during the winter, starts hot, cold or freezing, wet or dry 1st time, everytime, so why pay more. Plus where are the horror stories amounting from daily correct use of E10 from the Sates or even main land Europe that have ran this fuel for years!
Nice little experiment. Not 100% scientific but more than good enough to prove a point.
In my uneducated opinion, I would only use E10 in an old car/bike to get me out of trouble. But only put in as little as possible to get me to the next petrol station, bearing in mind that its not as economical as E5. I wouldn't want to leave E10 in the fuel lines for any length of time, even overnight. I guess E5 and E10 would mix together alright and not separate?
Nice vid, thumbs up
Although my car is "supposedly" ok for e10 fuel, I started using the 99 octane e5 in my little Street KA (no, I'm not a hairdresser) on recommendation by a friend. And what a difference... The engine smoothed out, it doesn't run as hot and I get way more mpg. It seems to have a bit more power too, I mean I don't have to put my foot down as much to achieve the same results. It's like my engine said thank you, as did my wallet.
We've been stuck with that E10 garbage in the US for a long time now. I had to replace every single rubber fuel hose on my '86 Nissan pickup because of it. The newer hoses work fine with the E10, but the truck runs a lot better on 100% gas. It's just hard to find that reliably, especially in rural areas where I usually am.
E10 will also lead to higher corrosion/gumminess/etc. in carbs. I only run 100% gas in my '93 Honda ATV and '76 CB550. Previous owner of the CB had put ethanol fuel in it and let it sit, the carbs were an absolute disaster.
I use 110LL (avgas) now on all of my older vehicles now.
Ethanol is a mistake in anything earlier that the 1990s IMO.
Obviously not using avgas in anything with a cat before any clever person points out its not compatible ;)
I think it's a mistake full stop, a guy I work with had a 2009 volkswagen jetta and he filled it with E10. Within a day he noticed a significant drop in power and by the end of the week it was hard to start and cut out at every junction. Previously he was getting around 400 miles on a full tank, with the tank full of E10 he got 250 miles. He then filled it with super unleaded E5 but the E10 had already damaged the fuel injection system and the cost of repair was more than half the value of the car so he traded it in for a diesel. We've got a petrol generator at work and someone filled it with E10, it hasn't been the same since. I will never use E10 in my bike.
100% gas is amazing if you’ve never used it. I was working In Iowa where it’s sold as “super” at 87 oct
My truck ran better than it ever had on e10 at 93oct
We have a station near a boat loading ramp that sells 91oct 100% and that stuff is like jet fuel in my tundra, but at $5.99 a gallon it’s not every day I’m buying 38gallons of that magic elixir
@@Heavywall70 you can still buy ethanol free petrol here in England, super unleaded but I've just did a price conversion, you're worried about $5.99 a gallon? We're paying $9.50 a gallon here.
@@sambrooks7862 Super unleaded is E5 which contains 5% ethanol .
Here in Thailand where I live ( a Brit) we have had Gasohol E20 which is a blend of 20% Ethanol, fermented from Sugar cane and/or Tapioca, a root carbohydrate crop, and 80% x 95 Octane gasoline. Myself and many Thais run petrol engined cars on this without problem. It is the cheapest equivalent 91 grade fuel, and burns cleanly with low emissions.
I have an Aprilia RSV Mille R Gen 1 from 2000 and I have always stuck with the E5 just to be safe.
Boys are we getting any bike sausage merch? I'd buy a sticker or 3
CBR 900 RRV Owner, regardless of the scientific arguments my gut says use super unleaded on my Carb bike. not for performance but just in case, as bits are old and have been super reliable in the 20 years I had it, winter stored in the UK with all the humidity, always runs after winter. No need to change..
Same here, 96 thunderace.
we love a 44teeth hoodie!!
anyone else getting less milage with vpower right now? me and my work mate seem to be guzzling fuel at a concerning rate compared to what we use to on vpower
A question - Was the ambient temperature at the time of the first and second dimensional measurement the same? All materials will have a temperature co-efficient of expansion.
Been running my Honda CB300F on E10 for eight years with zero problems. Book says I can use E20 as well.
I think Indycars in the USA run on 100% ethanol!
I drive a 22 year old E38 BMW 728i and I'm getting significantly less MPG using the new E10 fuel so I use the more expensive E5.
Glad I got rid of my 740 E38 last year or I wouldn't be able to afford the fuel.
If it's the same as the 320i and 540i of that vintage, the BMW manual will contain a strong advisory to use 98 RON or as close to it as much as possible anyway: I guess these lovely BMW engines are tuned to run on super-high-octane fuel. BMW claims "all" its cars can TOLERATE (emphasis mine) E10 though, I believe.
Nice one Boothy,ive got 3 gsxrs oilers and had probs recently,these bike were restored with all new seals in the carbs a couple of years ago,ive just done the carbs again,on my 750 as it was running like shyt,new seals ,now runs good again,coincedence................doubt it.will be doing the carbs on my 1100 again as i just dont want to have another spoilt ride.
I came to the same conclusion, but through a slightly quicker process... "If the government say it's safe, then it clearly isn't safe". 👍😂
MCN have stated that Esso has confirmed that their super unleaded had no ethanol in it in many areas on UK. This is despite a pump label to the contrary saying it does have ethanol. This might not be the case in areas where Esso gets its fuel from other oil companies.
Some E5 is actually E0 ! You just need to check and it’s what I always leave, if anything, over winter …
Interesting experiment monsieur Booth. Try some magnesium if you do a similar experiment again, also you have to burn more ethanol to get the same energy as petrol, not so good for the environment, better for the economy, if you know what I mean.
Worth noting that the real ethanol content of any given brand is not necessarily 5% or 10% for either of them - they are maximum figures, not minimum. E.g. as some below have mentioned, certain top end E5 labelled ones have none in them at all.
Apart from the reduced thermal content, the nasty effect of higher ethanol mixtures is the reduced “shelf life”, as the ethanol tends to be preferential to water, rather than the petroleum part of it, so in the long term it will tend to settle below the petroleum part, so there would be a layer of water/ethanol mix down below that could end up being sucked into the fuel system; not nice. Thus it’s probably a good idea to avoid storing it too long, say over winter.
Whether this has any effect on the performance of the Evaporative Emissions Control System (EVAP), which is a feature of modern petrol fueled cars, I don’t know. However, as the watery mix is under the rest of it, it seems unlikely that much of it will evaporate compared with the oily part; over to you!
Well done Boothy, I thought that was well presented. I never put that E10 crap in my bikes or cars
E5 made by Shell, Exxon and BP is free of ethanol! Here in the Netherlands anyway. So it sure does make a difference.
Same in most of the south of England, while in the north of England (areas fed by Stanlow refinery), it contains between 1 and 5%. E10 contains 5 to 7½% depending on brand and location.
None of the above implies that the bio-ethanol content couldn't be ramped up to the maximum permissible five or ten per cent later on.
I have a 06 triumph sprint and e 10 really fucked it up after only leaving the bike standing for three weeks . The bike will not start and the fuel tank has swollen making difficult to remove . I have replaced the petrol now the runs but very rough.
I think we just need to refer to our American cousins who've had E10 for years and report rubber pipes eroded from the inside out turning them mushy, also older American cars running on carbs getting gummed up and running like crap. There's also plenty of UK car drivers reporting rough running and poor performance on E10 that's cured by going onto super E5 fuel. Rather than pay more for E5 I've bought some ester petrol ethanol additive and add 50ml every time I fill up, only time will tell if it works or it's just another "snake oil" product.
Hi did you reach a verdict on your ethanol additive?
Too many variables ie combustion engine serviced by a garage ( are they using OEM parts or cheaper alternatives)
In a vented holding receptical what is the atmospheric pressure/water percentage/humidity etc.
What additives are added as different retailers have different mixtures.
Esso 99 Octane is actually 0% ethanol. So I use it in all my classic cars. More expensive but worth it.
Yes at most Esso stations but not all! (best to check)
But is it more expensive? Considering the significant drop in economy and the potential damage it causes I'd say it's worth the extra few pennies a litre.
@@sambrooks7862 yes but NOO all Esso stations sell E0, some are E5. You need to check!
@@andyxox4168 sorry, what I meant was the fuel containing ethanol may cost a few pennies less a litre but considering it gives less mpg and can potentially damage your engine long term it's probably more expensive.
In my ford c-max, I used E10 a couple of times and my car made lots of odd noises from my fuel tank and cat. Went back to E5, car was happy again. It didn't cut out or affect the acceleration as such but did make odd noises whilst on the E10. So for now until I understand more. I shall keep to the E5 for now.
well my 1.6 turbo Tuscon 2016. Reg Unleaded E5 450 miles a tank, Reg unleaded E10 400 miles a tank slight less power. I use Super Unleaded E5 now 475 miles plus better power delivery. noticed the difference from E10 regular, from e5 Regular not worth it.
So i tend to use E5 Super unleaded.
I get better milage and power delivery so really the same price as E10 Regular.
It's been e10 here in the us for a real long time. I've stored a carbureted bikes with that e10 without issue. the vacuum petcock has to work tho, cuz normal non ethonal gas will ruin a carb just the same if it dribbles.
My SV650 has had no dramas on E10 or E5 (touch wood) as far as I can tell it runs exactly the same on each fuel type.
My bike is 30 years old and I haven't noticed any corrosion or anything like that but it's definitely down on power. I used to be able Clutch up in 2nd gear but not anymore
Look at fuel tank expansion in Ducati 1098s. Mine expanded after standing for a few months UK bike UK fuel well before the days of e10.
My 2L engine was SO sluggish and slow with E10. Next fill with E5 or VPower and the response was significantly better. So it is not a "feeling" or "all in your head", you can tell from the torque response on first gear.
Anyone any idea when e5 was introduced in UK, as opposed to100% petrol.
Can't recall anyone kicking off over it. How can an extra 5% have Soooo much effect. Just asking.
Most e5 is about 0-2.5% ethanol but E10 is kicking it up in the 7.5% mostly that's what's causing the issues gunking fuel systems up and causing plastic tanks to swell.
@@zedddddful I guess that may be true of 'present' e5, as its premium ie super unleaded, however previous 95 octane standard unleaded e5 will have been 5% ethanol.
Been using in zx6 for months no issues as yet. I don't let it sit for too long tho
E10 is designed to help get rid of older cars, it was the same when they shafted drivers of leaded cars. They need to push the green agenda don't you know.
E10 fuel in My bike and my MPG has dropped and less miles to a tank. That biking holiday this summer is going to cost a lot more
I don't know what's happening with my car's got a 59 plate i10 that doesn't seem to run any different mpg about the same but I also have a T reg Micra that goes better than it ever has in the 15 years of ownership but but mpg always been rubbish at about 40 ish had to replace a rusty fuel pump but that was with E5 and rubber pipes had become hard I just wondered if the extra ethenol was acting as a cleaning agent I don't have much of a choice as only have supermarket fuel round here
My dad runs an old triumph from the 70s and he ran it on e10 for 1 tank and it caused the engin to get very hot then when he changed to e5 it ran a lot colder noticeable it was I do the same on my old Honda
Using food for fuel is farking stupid, first the cost of the diesel used to grow the corn and adding the mpg hit of some 10% and the answer is clearly that adding ethanol to petrol is stupid unless you are going for the power bump of E85
I want to know the difference in mileage. I feel that even in my car I get more mileage from e5. And working out the difference in price. It's overall cheaper for me. Anyone else got any research on this?
I’ve used E10 since 2009 in all my vehicles. I keep fuel records for all of them. I have found no noticeable difference in fuel economy. Having a roof rack, even an empty one or having a bicycle on a rear mounted rack make significant differences. E10 is fine.
By contrast to David, I found a noticeable drop in performance, requiring approximately 4 tanks of E10 to every 3 tanks of E5. This will vary by vehicle of course, the best way to gauge the difference is to test it yourself. An interesting post on this topic came up on the CBR500R owners FB page a few weeks back, with answers varying from 'E10 is more efficient' to a '25% drop on E10', 'though obviously age of engine may be a factor too.
2016 Tuscnon 1.6T, E5 reg unleaded 450 miles a tank, now with E10 400 miles / 410 miles. i use E5 super and get 475mile easily. The power is smoother to, less revs.
@@davidmatthews3093 what country are you in? I find it strange that people in the states say that they've never had any problems with E10 whereas it seems that many people in the uk have, maybe the difference in the climate affects it?
We’ve been running up to 10% ethanol in the states for decades across all octane rating fuels (barring ethanol free) and no adverse issues happen unless you are neglecting things. No worry
My car and bike run like shit on E10. The US has had inferior quality fuels for decades so you probably have never noticed
@@gpzfan5272 yep when your used to shit throttle response rough idling and flat spots how would you notice.
If you are used to eating sh!t then you will love sh!t.
Can't help but notice you didn't test the fuel, how do you know the E5 was 5% ethanol and the E10 was really 10%?
Doesn't really matter does it? You could call them banana juice and lemon water and the results would still be the same, and you'd still know whether either of them were unsafe to use.
Good question
It sounds like he's in the north of England, where typically, at present, "E5" contains from 1 to 5% bio-ethanol, while "E10" contains from 5% to 7½%. See "The Fuel Reviewer".
I get vapor lock with E10, but not with E5, Carburettor bike. The fuel line does run right by the cylinder head and radiator though, so perhaps that is a factor, you can literally see the fuel bubble with e10, but e5 doesn't do the same.
Ethnol in the fuel swole the rubbers in the fuel tap of my 97 Cb600f3, it was so bad it would not start.
All we use in America is e10 and our fuel systems aren’t fucked even after 30 years of use. It won’t make a difference other than maybe mileage and power but you wouldn’t notice the power. I’ve put ethanol free gas in my bike out of curiosity and it didn’t make any difference
I use e5 as e 10 doesn't last as long and I can notice its down on power 🤷♂️
We bought a brand new motorbike last year, because i wanted something that could run on both types.
One thing i have noticed when had to use e10 was the bike runs more rougher and dont get same milage out of it.
A lot of people prob think the using more fuel part doesnt help the world but yes you use a little more e10 but the less co2 made from it is an overall benefit is what the government is going with.
Im going to keep using e5 where i can as bike runs better and better milage out of it.
Less CO2 in use - allegedly. It still takes a lot to make and transport it though so that extra use is harming the planet somewhere down the line.
@@siraff4461
Well its the same tankers that transport e10 as they did e5. No change there.
Its the government making people change as so many people out there dont care about how well or efficient they drive, they drive because need to, not want to, so will make more co2.
So government thinks by giving a less polluting fuel to the people, it will make less co2 even though they use a bit more than using e5 fuel.
Good work, my liege.
my take after trying both fuels and reading/watching many vids, is that yes, E5 costs more and the extra mpg is pretty much offset by the extra cost, BUT my motorbike at least 'feels' perkier and smoother on E5, so if it's not costing any more in real terms, it surely makes more sense to use E5. i do feel though that as more and more of us realise E10 is a con and the difference in mpg is much more than the 1% they say, then the price of E5 will rise, in much the same way they conned millions switching to diesel. and btw the 'emissions' argument is claptrap when you look at how much pollution modern vehicles emit, such as my euro5 bike, and as older vehicles need E5 anyway, it's all about taxation and not combatting pollution is it?
Just check with the manufacturer, they are all different depending on what materials they used (there are many different types of rubber...).
As an example, Triumph say all their bikes manufacturers since 1996 are compatible with E10.
Aprillia say using E10 is a safety issue in bikes older than 2011.
My car drinks 15% more fuel on E10, but it runs smoother on it probably due to the anti knock properties of ethanol based fuels. Its an old engine, 2001 vauxhall eco tech with 170,000 miles on it.
That was some strange stock footage at the pumps
I use E5 in my 2013 Ford focus 1.0 ecoboom. And get way better MPG too, so in the long run I save money
There are people who think that their cars run worse on the new petrol with E10. Since E10 contain less energy at least in theory, the car should consume more fuel per mile. There is actually a car that consumes less gasoline at 98 octane even though the ethanol content is exactly the same. according to a study from the United States. examples of a car that gets lower consumption with 98 octane are the Ford Mustang and Ford F150
what about a 2 stroke engine from say.. a chainsaw?
would there be any difference apart from of course the extra (little) performance gain which i don't care about at all.
It may save the planet which I doubt but it definitely will destroy many engines and ultimately vehicles😢
Did you know that Esso synergy supreme E5 has ZERO ethanol in it?
In most parts of the UK this synergy supreme is E0!
I run it in my older carbed bikes with no ill effects when left for a period of time.
Esso super unleaded, in most parts of the uk. Does not have ethanol in it apparently, but they have to advertise it as E5.
Read this in a magazine recently, not sure if its true.
Maybe someone could shine some light on it 🤷🏻♂️
It's true, and it applies to many other brands in much of southern England. Up north, Devon and Cornwall will often get more ethanol though.
"E10" is currently typically 5 to 7½% ethanol in the UK rather than the full 10% but I wouldn't be surprised if that changes some time in the future.
A crude experiment but at least it was an experiment, revealing some possible issues. Having at one time worked in the rubber industry I can confirm that some automotive rubber compounds, used in fuel hoses, seals, o rings, gaskets, components etc, will be adversly affected by ethanol. More recent vehicles will use specific types of rubber for components and parts exposed to ethanol blend fuels, which will fully resist it's effects. Also realise that most vehicles are exported globally, and many countries have been using ethanol fuels for many years, in particular the USA. So those vehicles would need to be compatible with local fuel availability, if for no other reason but warranty issues. One of the worst problems with ethanol blend fuels is water attraction, which can cause severe corrosion in susceptable components. Using a fuel stabiliser mixed with the fuel in tank and run through the engine before any storage period longer than a month or 2, will minimise this problem. The bigger picture is though, why the government implemented this flawed strategy, ethanol fuel increases fuel consumption, which negates the theoretical saving in CO2 emmisions. And if everybody goes over to E5 SUL, it makes the excercise pointless, apart from increasing revenue and profits, as already mentioned.

Can you do a mpg comparison I’m certain my 1 yo Aprilia gets better economy using E5
You can still get E5 standard in Northern Ireland, so get it whilst we can. That said my bike is now pissing petrol from its hoses now
