I've seen lots of drivers lately deliberately driving at 60 or even 50 mph on the motorways and dual carriageways in an attempt to save fuel. But does it actually work? and if so, how much money will it save you?

watch video from 7.11 to learn why petrol pumps have a minimum amount written on them . ua-cam.com/video/_S2sGMH_u18/v-deo.html
FYI Joel there is no minimum delivery on UK petrol pumps. When it quotes a minimum quantity that's to ensure that you get the stated quantity at the stated price. Its a weights and measurement function. In reality you can by 10p worth of fuel.
Really good video! I reckon (ignoring very high performance cars) the slower your car is the greater the saving will be. A 1L engine has to work quite a bit harder to do 70MPH instead of 60MPH but a 3L probably wouldn’t care
Have to admit, i drive at 65mph and find thats the ideal speed for mpg, i dont see an issue as long qs your going faster than a HGV and slowing them down. Also depends on the vehicle and your gear ratio's
I’m interested to see a cruise control vs non cruise control efficiency test
No minimum delivery on fuel pumps mate, that's just for "calibration" purposes. Some idiot did a video on it... it does mean that possibly, 1.23 litres (for example) isn't 100% accurate, it could be a few ml more or less.
As somone who's seen this video that's exactly what popped into my head when Joel mentioned minimum delivery 😂😂😂
Yes, saw that video, someone who drives all over to experience our delightful motorway services....
Thats interesting, I didn’t know that… im going to watch your video now to educate myself!
Nice car.
Please redo this over a longer more representative distance, and be able to factor in min fuelling. Probably best to do from one 'services' to another to remove the variance of urban driving (a big factor on such a short distance)
Great video, I love these sort of tests.
I tested my car's effiency by checking how efficient the car was driving at various speeds. What I found out was my car is most efficient when driving 110km/h(90 or 100 resulted in the same 4l/100km). And between 115 -135km/h it was using about 5l/100km. Anything over 140km/h kept increasing the fuel consumption to about 6-7l/100km till 220km/h. At top speed/255kmh it was using over 10-15l.
So getting to know your car better really helps. Like the sweetest spot of my car is 60km/h @ 3l/100km/h, while slower speeds used more.
I regularly drive between the midlands and Carlisle, around 190 miles. In my 3 pot micra, the difference between 60mph and 70mph can be as much as 15mpg - 60mpg vs 45mpg on average. Quite a chunky difference. Time wise it doesn’t seem much different but that’s rarely important and just means more podcast time. I only do 60 in lane 1, though. I speed up to help flow if needed when overtaking.
Just so you are aware Joel (and anyone else reading) that minimum delivery amount isn’t actually a minimum requirement of fuel you must put in. It’s the minimum amount that specific petrol stations require you to fill to to get an accurate reading of that amount. You can put less than 2 litres in. That is just there way of saying if you put in 2 litres and above then you are accurately getting 2 litres and above however anything lower, let’s say 1 litre you may only be getting 900ml.
It’s purely an accuracy of fuel delivery amount statement (which is why it varies between petrol stations).
I recently done a similar experiment with my 2012 Focus 1.6tdci.... I fill it up and on the motorway I do 70....plus, and I get around 400 miles to a tank. So I decided to drive slower on the motorway, 50-60, sitting behind a HGV, or just fast enough that I'm not getting caught by HGVs. Driving at the slower speed I got 517 miles out the full tank. I'm 25 miles a day, 5 days a week to work, and the extra 117 miles is like and extra week of commuting for free. I done it for maybe two months, then went back to going fast as my patience ran out, I'd rather get there quickly than efficiently! 😂😂😂 Great video, love this kind of thing! ❤❤❤
You’ve saved fuel by sitting behind the truck too, it’s called drafting and works a treat
@@RobBeveridgeCarsOhhh, that slipstream! 😊
Nobody ever compares driving at 70mph vs 140mph
You will literally half your journey time on the motorway and have so much more fun in the process 🤭
Unless you are caught. Walking home takes some time.
The savings are negligible. You should always drive (up to the speed limit) as the road and traffic conditions dictate.
The problem with driving at 60 is that you become involved with trucks who are almost all doing 56 (plus) mph. To get past quickly, some turn of speed beyond 60 is required. My partner does long M’way commutes in a Hyundai i20N (a small car with decent power) and does 70 (plus) yet still returns 45mpg. My daily is an under-powered 3.5 tonne large camper which is happy at 60, struggles at 70 and drinks fuel worse than I drink alcohol….. not together, of course.
I find trying to do 70 these days is impossible for more than a handful of miles. People seem incapable of maintaining any kind of consistency when driving. I find 62 is enough to not get involved with idiots who want to do 60....40....75....80....55 and quick enough to not interfere with trucks. On a decent hour ish run at 62 I've seen over 50 mpg which is brilliant. I can't abide braking on a motorway. Braking should be reserved to avoid a collision not used as a default method of scrubbing off speed. People need to learn to read the road and coast rather than brake.
It was interesting to hear your comment on people's slower driving habits especially on motorways. I have been away from the UK, on my return l had reason to drive from Hampshire to Kent along the M 25 and noticed the slower driving speeds, at first l thought I might have missed motorway speed restrictions but this was not the case on this occasion and as you rightly say people seem to be driving noticably slower.
Keep up the great videos and stay safe.
Great little experiment bro! Cheers Kirk
That's not what minimum delivery means, that means 2 litres is the minimum amount that will give you an accurate reading on the pump
Good video Joel, and like you, i was surprised the difference was as much as 10%
On my Jaguar SVR it uses more fuel at 60 than 70 because the engine is not running at anything like efficient rpm at 60. It’s doing 1500 at 70 which is just getting to its efficiency level. It will return 28.5 mpg at that speed on a proper run. Not that I care because you don’t buy a 5 litre V8 if you want to save fuel.
I think people are driving slower on motorways not so much to save fuel but because they are paranoid about the wall to wall speed cameras. I know I am!
That would defy the laws of physics. If you went 60 and matched that speed to the appropriate gear, you’d save fuel compared to 70.
Eg: E class I had would cruise at 70 at 1150 rpm in 9th gear and average 62mpg.
At 60 it would be approx 1250 rpm in 8th and average 68mpg.
Great video, thanks!
If the motorway is fairly empty, I try to go at the speed limit.
If it's busy, I try to keep to around 60 as I find targeting 70 a lot more unsafe because people tend not to keep a safe distance, and you get some zig-zagging through trying to 'make progress' and save 30 seconds on their journey. Same when the weather is bad.
A great tip / comment from you was the one referring to travelling at 60 mph may hold up bigger / heavier vehicles (lorries) and unfortunately there are too many old codgers (I am one of them btw) that do hold up traffic by travelling TOO SLOWLY. (me an old codger, but NOT one that travels too slowly - always aware of that lorry / tanker that needs to use its momentum to get up an incline).
A great attempt at trying to carry out a "controlled" test.
Great video. Very interesting. And a beautiful car (in the 'correct' colour).
'I hope that makes sense. Well it does to me'. Classic.
I fancy a go in one of those alpines 👍🏻
Not got a exotic engine but supposed to be great to drive
Shame it's a automatic, putting a automatic gearbox in a sports car is sacrilegious!
Maybe it's for the American market as they like their cars & jeeps boring! Or maybe they haven't got the brains to drive a manual?
the latter lol@@freddythefrog70
The minimum delivery isn't from a sales point, you buy as little as you want, the minimum delivery is for accuracy of fuel quantities. They say that below 2 litres they cant guarantee the correct volume of fuel delivered will be exact.
I mix my driving up, but if I do drive slower, it's behind a lorry so I don't inconvenience anyone else, but as I've heard the speed limit is just that not a target. And I cover around 50,000 miles per year.
Good stuff, GS, GD!
You can fill below minimum delivery it’s just that the figure won’t be as accurate. There’s a good auto shenanigans video on it.
HGV'S are limited to 56 mph, so many people driving at 60 will be holding them up, as their spedo will be over reading by 5-10%. 65 mph is the sweet spot.
Very interesting, Joel ….. youdidn’t factor in the extra time spent at fuel stations when doing 70 🙂
But, agree with your comment in the video - would be more interesting to do this test with an 8i0 vs 70 test …. Eg, for my summer holiday, I took my 2.7 L320 Range Rover Sport to Germany / France (yes, it didn’t break down!), and it returned respectable economy at 70-75MPH (c. 34mpg), but if I’d gone through France at 130kph, I would have expected a noticeable drop in fuel economy, as the car is working a lot harder.
Suggest you do a part 2 …. Take the Volvo for a baseline/compare test in France and see how you go 🙂
Keep up the work - good and interesting content.
In the United States, the only time you are allowed to drive substantially below the posted speed limit is if there are adverse weather conditions or towing a trailer.
Great video man! My brother always used to drive at 60 instead of 70 in his diesel and always said it made a difference. I tried it for a whole tank in my 4.4L petrol car and it did make a difference but not as much of a difference as the smaller capacity diesel (I guess what's 10mph to a V8?). Luckily I don't really need to save fuel but it's a very interesting test and I do like the science behind this stuff. Another thing to think about is, if you save fuel for driving at 60mph but it costs you a little more time that's all good. But if you consider driving at 70 will use the fuel quicker you will surely only waste more time having to fill up sooner / more often. I'm sure it would still be less time used though due to fill ups not taking long at all. Still interesting none the less. Cheers for the video 👌👍
You should watch Auto Shenanigans’ video on the minimum delivery of fuel pumps. Also, I’m sure it’s been said elsewhere but you should have probably driven to and from each petrol station for each MPG test rather than once in each direction as the hills may affect your consumption.
i had an Hyundai ioniq full hybrid driving 2 mph less made a massive difference on a motorway journey 68 compared to 70 - im now in a renault austral again full hybrid bigger heavier car but different type of full hybrid it has a 3 cylinder 1.2 engine and ive also done this test in it and so long as im under 76mph i still get ev mode and have found it makes no difference at all - the new versions of hybrid drive train make a big difference plus this car still gives me 200 bhp - my point is the manufactures are improving all this for us to drive as we would in a normal petrol car
but love your content bud always enjoy it thanks
This was a very good video with scope for a series with multiple different car model's. I'd imagine a brick shaped 1 litre polo may have greater savings... my 15yr old astra 1.8 petrol probably a massive saving
I think 50 mph 70 mph would have also been a good comparison. Great content, thanks for the channel!
You shouldn’t do 50 on a motorway unless you want to anger all the hard working truckers
@@RobBeveridgeCars How so Rob? You would save them fuel too.
@@RobBeveridgeCarsit’s not illegal and most busy motorways during commuter hours are limited to 40-60mph anyway. You going at 70mph will very literally get you 10 miles an hour faster somewhere IF you maintained exactly 70 for the entire hour, not factoring in service stops, traffic, junctions, driving on a and b roads etc
Good experiment. Getting up to and down from intended cruise control has a bigger factor in fuel efficiency.
Good test, beautiful car the A10 is a little gem
To short a distance to test,you need at least 50 miles.
Speaking personally, when doing 60mph in my previous work van I used to get 750 miles to a tank. Doing 70 that figured dropped to roughly 600 miles. Thats per tank. So i would argue your point about the amount of saving being negligible.
The more aero inefficient the vehicle, the greater the effect of the speed reduction. So it’s much more noticeable in a van
When I do very long journeys across Europe, I tend to cruise at 60mph. Haven't been sceintific about data but get up to 700 miles per tank/ 50 litres of diesel. When commuting (mostly motorway at 70 or just over) I rarely exceed 500 miles per tank.
When I was in the UK last summer I noticed lots of people driving really slow, even slower than the already low 70 limit.
In a more aerodynamic car the difference should be less than an mpv. But the set-up of the alpina isn’t great for it, usually the Germans are more designed for it.
A bigger SUV makes a bigger difference.
That being said: test have been done in France and the difference between 130 and 110 kph in a megane 1.5DCI was considerable( 1.5l/100km difference). On the other hand: The same has been done in a BMW 530D and the difference was less than half a litre.
My parents often drive 100kph instead of 120kph now that they are retired and in a 2011 Volvo XC60 diesel it gives them almost 200km extra range. I will say: I drive a lot for work for bigger distances: and it is more economical to drive faster since the fuelsaving don’t compare to the cost of working 20 min more.
Biggest change in my fuel consumption: The weather. Now that the weather has turned (wet roads and colder) my consumption has gone up from 6.9l/100km to 8l/100km.
Don't worry about the 'minimum delivery' - the pump will delivery how much or how little fuel you want.
I notice you used E10 fuel - it would be interesting to see what difference using E5/super unleaded fuel makes. In my expereince cars run worse on E10 with far inferior fuel economy than on E5
A great experiment - but an absolute no no filming outside the car on fuel station forecourts - it is dangerous and illegal to use any sort of device in these areas - there are signs and notices everywhere.
It's sad that people are penny pinching on the roads like this.. while sitting in the middle lane.. with a tail light out.. I see it every day.
useful video Joel. Fuel consumption is exponential over 60mph.. it would be interesting if you get a boxy car (not the ALPINE 😂) such as big suv and do the same at 50mph and at the speed limit...
Damn good question
I go for drives with the mrs on the motorway and sometimes sit at 60mph when there isn’t much traffic in the evening. I have a BMW 530d and it doesn’t make to much of a difference 60,70 or more. It is very economical either way. 👍
My audi 2 years old gets 53mpg at 60mph v 44mpg at 70mph. Ended up here as was curious what others get
Thanks for watching
In my experience when I have done tests, the fill tank method has been very inaccurate at such a short distance as the pump does not click off at the same level. For these short journeys the trip computer will actually be more accurate, especially when the comparison is in the same car. You could fill it until you see fuel at the top of the neck of the filler but this is not safe and may damage the EVAP system.
I admit. Fucking interesting video. Keep it up man.
Thanks!
I've got a 3.0ltr supercharged XJ X351. At 70mph it's doing 1500 rpm. At 60 about 1350rpm. I never drive at 60 if i can go faster. However the difference between 70mph (1500rpm) and 80mph (1650rpm) in fuel consumption is negligible. At 70 i average (mototway in CC) 38mpg at 80 36mpg.
Depends more in the road conditions, if you are not obstructing go for whatever speed is most efficient in your car. If it's busy, just drive normally.
Interestingly Spain (about a decade ago), reduced our 120kph limit to 110kph throughout the entire country, while in the middle of a finical criss. Needless to say this didn't go down at all well with the public, and they shortly after raised it back to 120kph. But think of all the signs they changed, then changed back, then the costs involved in doing it. Speaks volumes.
Interesting experiment. I have a Mk3 RS Clio and find I average ~5mpg better at 60 vs 70mph, 40 vs 35mpg respectively. I'll be buying an Alpine A110 as my next car so interesting to see how that will scale. It would also be interesting to run the same test but with Shell V-Power, to see if their claim of improved efficiency stands up. I tend to agree the fuel saving costs of 60 vs 70mph don't balance out the inconvenience, to both other road users and the time lost over long journeys. Also, over the 12,000 miles annual average the majority of those miles won't be in an environment where one can choose to drive at 60 vs 70mph, i.e city driving, traffic etc, so the saving would likely be much less.
Its simple. Windvresitancevincteades with the power of 2 with speed, and the extra power another factor.
So you need 8 times the power for double speed. And yes, this costs fuel.
It depends on so many variables is the turbo on boost, what’s the gearing and final drive and mapping.
60 or 70 it doesn't matter, that's what the fast lane is for you're not holding anyone up at all. 60 is a more relaxing drive, not everyone is in a hurry and some of us enjoy the journey more than the destinations. So we gain 1.3 days of relaxing pleasure and 210 quid a year, plus the lower speed is far more mechanically sympathetic, everything last longer and you maintain it's value..... Oh f'''' me I've turned into my dad. 🤣
It happens with age, you slow down and take things easy. B roads are only 60mph anyway.
Good luck josh on the great British bake of I hope you win it 🎉
Tbh south of Preston its hard to average 70 as its so busy . My diesel mild hybrid Sportage has averaged 58 and 60 mpg from Gretna to Silverstone for Moto GP
Do you think if either garages had to advertise cost of fuel per gallon as well as litre , or cars are advertised miles per litre as well as gallon would help consumers better understand real cost of their vehicles consumption .?
Interesting video Joel, considered this myself. Also at the slower speed the car is driving for longer so does that come into consideration.
No because that’s what the miles per gallon calculation accounts for
'Great vid' Joel. 'Interesting to see what a difference it would make over months of driving.
Interesting video ..... more from the comments perhaps than the mpg test. Firstly.... 70 mph is the speed limit, not a mandatory minimum speed so it’s disappointing to see a negative bias to those driving at 60mph. Also.... a 10 to 12% saving in any other scenario is surely a worthy one? If you had an 11% pay increase or indeed pay cut, I certainly feel people would not dismiss or trivialise it?
And lastly..... whilst not mentioned, what about reduced emissions? The reduction in emissions benefits everyone even if the lure of a personal 10% saving does not. I’m as much of a petrolhead as any you’ll find, but the need to reduce pollution is a rapidly approaching train wreck without significant intervention.
Well, if we drive with no or little traffic then the speed difference is more relevant. But frequently you see someone steam past you on the motorway/dual carriage and funny thing is you are right behind them at the roundabout. The real life time difference in normal driving conditions makes little difference.
Totally depends on the gearbox at this Speed
Let’s hope the Gov doesn’t see this 😂
In a smaller engined car with less power the difference can be more.
I’m not really sure understand why people are driving at 60 mph. It’s mostly because with the inevitable roadworks on any journey on the motorway you don’t actually save any significant time going 70 over 60. Very much the case here at the Almondsbury interchange where there is no point going over 60 even if you can for a bit.
I drive slower because i drive a land rover, and i still only get 19 to the gallon 😂
Simple answer is BIG YES. Wind resistance is squared with speed (velocity squared), meaning the increase in drag is exponential as you speed up.
Wr😅
I do on 4/5 drives. Drive 62 ish. And it is sketchy and best avoided unless quiet roads. 11/12%. Would think more. Isn’t worth driving slower then ….thought more like 20%
I drive my 2009 diesel Octavia at 60mph on the motorway, and im averaging around 62mpg
What’s the difference between 30 and 20mph?
Are people driving slower through fear of being prosecuted for exceeding speed limit?
Squirt the rest of it in the bin like Clarkson 😅
I drive my old defender at max 62mph I sit behind a lorry for miles it really makes the trip less stressful. I can’t reach 70
Stay in lane 1 and Save a few quid on fuel to pay for the stone chips on your bonnet 🤔 🚛 genius 👍
Difference is proportional to the speed and time. I'll continue to drive at 70.
I think it’s more to do with your driving style I have a BMW x3 35d and get 32 mpg my wife has a Mercedes Glc 220 d and gets 31 mpg.😮
The difference would have been bigger if the car was less aerodynamic.
What happened to the S-type?
For a sleek streamlines car like that the savings are low. But if you own an SUV, with the aerodynamics of a brick, then the savings are significantly more. I think it was an old Top Gear episode that tested using a lorry as a wind break and showed significant savings on fuel - but was dangerous if you got too close !
Doesn’t matter the shape. Wind resistance is SQUARED with speed. Meaning it’s exponential.
As you.said air resistance is the square of the speed. However since you are covering more distance the drag component of the fuel usage is proportional to speed. I demonstrated this in Germany when I got to drive 140 miles in one hour, my fuel usage was only double what my cat does at 70.
Mmm interesting, i wonder if eco would make much difference 🤷🏻♂️
Nice ! i also think the roads in Iceland are slightly better than that one. i find the premium fuel in my Golf GTi has it running a lot better than on normal e10. It will run on e10, but it runs like a bag of spanners.
Are we going to be getting anymore Audi TT content ?
I drive slower on longer journeys, its far less stressful.
In my Civic - 70mpg at 50mph or 50mpg at 70mph
‘The so called fuel crisis’ err do you mean the one that was a key driver of the cost of living crisis or just a fantasy…
Do it over 100/200 miles jo..massive difference
Did you do a fuel vid with the Porsche? I just got one 😈😈
Regards
Great video, but these days as you'll barely reach 70 mph on a motorway for a sustained period of time due to the vast majority of drivers that don't understand the concept of overtaking lanes (as you've pointed out in a previous video)
Rather than setting up more and more speed traps on motorways to catch motorists exceeding the woefully out of date 70 mph speed limit, maybe the government should spend some time educating the useless drivers that are so unaware of the highway code. And then everyone might end up improving their mpg with less slowing down for inconsiderate drivers that hog all three lanes unnecessarily
I drive everywhere at 140mph i get everywhere twice as fast so my engine runs for half the time meaning i use half the fuel best money saving tip your welcome
No, that is not how it works 😂
@@itsjoel it works like that in my head though 🤣🤣🤣
Unfortunately I think most of the people driving at 50, 55, 60, 62, 65 mph seem to be the same ones that aren't looking at the road but looking down at their crotch, seemingly doom scrolling on social media, or messaging on WhatsApp etc.
i spent nealry two years driving 38 mile each way for work, had a2 litre audi a3 and learned to drive at about 60 through the motorway (around 30 mile) i ended up saving about a 10er a week, fuel prices were aound 1.30 a litre (2020-2021) im now driving 3 days a week and doing around 100mile a day getting to and from work in a 2litre bi turbo insignia and still spending the same money at more expensive diesel and doing 70!? work that out lol...suppose it just depends on the car!
the police can prosecute for going to slow on a motorway and also classed as careless driving
Might save money but it’s bloody boring and tedious. I’d rather get a move on and have time for other things.
there is no minimum amount you have to put in at the petrol station . what your reading on the pump is the accuracy of the pump ,it,s guaranteed to be accurate 100% if put more than 2 litres in ,anything under 2 litres they cannot guarantee it will be a 100% accurate .some pumps say 5 litres ,they usually have longer hoses ,and are known not to be as accurate as other pumps installed everybody get,s this wrong ,thinking it,s the minimum amount you can put in ,you can put in 10p if you want .
I value my time at a higher rate than the few pence I'd save the boss, driving slower. Flat out always.
Dacia vibes all over the place
I agree with what some of the others are said, regarding speed cameras. The M1, particularly is absolutely horrendous. However, that said keeping my 3 L six cylinder SUV at 70 it’s only ticking over at 1500 rpm and I’m getting almost 40 to the gallon versus the published overall figure of 33 mpg and I don’t feel I’m holding the traffic up or that it had a much in terms of journey time.
Lost me when you said it was more dangerous to drive at 60mph, sorry but that’s just a ridiculous statement.
330e is barely cruising at 70 in 8speed revs are low
How about 20mph v 30mph?
I completely disagree, in regards to people slowing down on motorways and dual carriageways. Whenever I’m on a motorway, if I’m doing 60mph, everyone overtakes like you’re going backwards, lorry’s etc catch up with you if you dip under 60mph, and don’t have cruise control…….
These days if you’re not doing 70mph plus, you’ll be getting over taken left right and centre. Perhaps it depends on where in the country you live? Everyone is in a rush here 😂
