- Everyone knows that Gasoline goes stale right?
Well see a generator start up with 5 year old gas, followed by my collector car, that has had gas in it's tank for 3 years.
This might not be the best practice, but it proves that modern gasoline does not turn to varnish sitting, and that it will still run just fine. Not that I am recommending that anyone do this, but these 2 engines started up no problem, and there was no fuel stabilizer added to the tank. Just regular unleaded in the generator and premium unleaded in the Supercoupe.
Before you ask, the color of the car is Chameleon Blue and it is an original ford color from 1995. It is a rare color, and this is a rare car, and that is why I am collecting it. The Super coupe was discontinued in 1995, and there was only just over 3,000 of them made, which makes this a very collectable car, especially given the color.
Most engines will probably fire right up with old gas in them but for those people out there that worry about things like that, yes it is not a terrible idea to drain the tank and put fresh stuff in. For cars that have sat for years though I would recommend pulling the fuse for the fuel pump (or anything else that would stop the car from starting but still allow it to crank) and this would be to allow the oil pressure to build up and get all around the engine before the engine fires. This is the ticking noise in your car after it fired up. Not a huge deal either but not a good idea to rev it straight away.
I don't care what anybody says this is a bad idea, I've always ran my carbs dry before storage on everything and never had any problems in fact it's people not draining their fuel that as a kid got me an endless supply of curbside lawnmowers/snow blowers lol.
Your a genius in your own mind😂
Buhahahahahahaha, you said carburetor 😂
Who on earth still uses carburetors ?
Although I drained as much gas as possible I started my truck for the first time with a good motor and it fired right up on the old gas (5 years old).
Do it with ethanol gas and it'll be stuffed in 2 months. Paid for my house with the money from rebuilding or replacing carbs the last 25 years. Thank you ethanol!
I would think the gas in the generator was ethanol gas as that one had regular for sure. I did burn it all off and refill it but the original gas was in there for about 7 years by the time it was used up. Going to convert that generator to natural gas one of these days. Just have to get a conversion kit.
scott king premium non-ethanol fuel only.
Ethanol gas in my volt been there for a year then computer made me burn it up.
um is ethanol unleaded? If not where is it bought?
@@ameerordimly1449 Ethanol is an alcohol additive to fuel in the US. In Iowa where I live, its the cheapest type of gasoline because its subsidized.
I personally wouldn't call two minutes of cranking a "start with no problem"
But it ran!!
Considering that it had not been turned on in two years
I counted 34 secs of cranking.
Lol for real
@@kchiem Your point. The gas was 5 years old and it needed to prime.
I just emptied and cleaned a motorcycle tank that had been sitting at room temp for around 2 - 3 years:
• the fuel had turned to a redish rust-coloured varnish - it _smelt_ more like wood varnish / creosote than petrol
• the carbon content had precipitated out into an abundance of hard black flakes at mm scale, the largest up to maybe 4 - 5 mm
The stench is still lingering hours later with all the windows open and fans blowing air out one side of the building..
Take it from me - old unleaded petrol is _proper nasty stuff_ and a bitch to clean up...
I had a little accident with a plugged up rain water drain hole on my motorcycle. Water got in the tank.
Drained the whole tank of watery fuel into a bucket. Got rid of all the water in the fuel by letting it stand, then decanting the fuel that floats on top of the water. Left the good part of the fuel sitting outside (in a jerry can) for half a year.
Today i poured it into the tank again, but performance definitely degraded. On the highway i felt like shifting up, because it vibrated as if it was in one gear too low, and my god the smell was awful. Stale fuel reeks.
Mixed it with some fresh fuel, and everything is fine again.
Fuel definitely degrades. You may not notice it in lower compression engines, but on my bike, it's very noticable.
Everybody says this is impossible.. but when I was a kid, my father got a 1964 Pontiac to start and run on what we estimate to be 12yr old gas, it had been sitting in a garage untouched for 12yrs. He then changed a bunch of gaskets & filters and put new tires on it. I can't say exactly what he did to it, I was about 8yrs old but he had it road worthy again in about 2 days.
We too had a car (1994 Renault 19 RT) just sitting around for years, but after charging the battery it started up pretty much immediately.
It's all marketing to sell gas stabilizer . My dad used to turn the gas off on his lawn mower and let it run until it stopped thinking that burning all the gas out (or draining the carb) was a good thing. Every spring he would curse and have to have the carburetor overhauled.
I tried to reason with him about the residue evaporating and gumming it up but my dad was stubborn. (only a grade 8 education) Myself I am a well educated engineer, electrical field, but I understand physics, and chemistry. I never turn the gas valve off unless I am transporting a power tool. Other than that I leave it on, so as the gas in the carburetor evaporates it will be replenished. So far I have never had to service any of my power tools, and I don't put gas line stabilizer in. It is best to keep the tank full so that condensation doesn't form on the inside of the tank and dilute the gas, but I don't follow that rule either, and so far have never had any problems.
Thanks for your video. We just had a northeast blizzard dumping 16" of snow. I couldn't start my Honda snowblower, bought last year and was used for only a couple of times. I've never learned how to maintain the gas engine and now I just learned about stale gas. I was frustrated because I was stuck in the snow. Since the snowblower is quite new, I couldn't find any instruction on the web as to how to get the carburetor out and clean it. Suddenly, I came across your video and got hope. The snowblower doesn't have an electric starter, so I just pull the manual starter for about a hundred time and got it started. Thanks again!
+Samuel Stone I learned years ago from a lawnmower repairman that keeping the tank full, and leaving the fuel valve on, ,so that fuel that evaporates from the float bowl will be replenished will keep it from varnishing up. Incidentally, the gas in this generator is 16 months older now than when I made the video, same gas, no new gas added, and I just cranked it up last week when we had a storm warning to make sure it would start. Took about as long as it did in this video, and it started right up no problem.
12voltvids Yes, the reason I had hope after seeing your video was because I noticed that the fuel valve was left on. Thanks!
+12voltvids What a success, it only took half a minute to start, whoopdedoo, and then you say that gas doesn't go stale, let me remind you that there are generators exactly like this but where you have to pull the cord to start them, meaning, with gas as old as yours, you can pull until your arm falls off, it would never start, ever. Gasoline goes stale because it's a mix of hidrocarbons of different lenghts, some of them very volatile, when the more volatile/shorter hydrocarbons evaporate you're left with long-chain hydrocarbons that can still burn just not as effectively (as we can testify by it taking 30 seconds of starter action for it to work), because longer chains are also more viscous, less passes by injectors or carb passages thus strangling the engine of fuel. So yeah, mythbust decades of science in fuel composition by starting a generator on stale gas, sounds about right, scientists are all stupid, you're the intelligent one.
anonimo ........rofflol
@@anonimoanonimo4544 Ya know, you can use an electric or battery powered drill and the right sized socket to turn over a pull-start small engine with minimal effort.
Stale gas in a tank lasts a lot longer than gas sitting in a carb bowl. The fact that gas goes bad is certainly not a myth, and with 10% ethanol it is worse now than ever. I repair small engines and about 75% of the issues I see are from gummed up carbs from gas sitting in the carb. Even one season will cause it.
I don't have much experience with gas-powered engines being stored for a while, but my current daily driver once was "stored" (out in the open) with 1/4 tank of E10 (premium if it matters) for about a year. I cranked it up from time to time just to keep things moving and the battery charged but when I put it back on the road, it still had roughly year old gas in the tank when I went to go fill it up. It ran the same as the day I parked it.
1 year is nothing
@@kenmastersmaster Well, I now have a truck sitting with a pretty much full tank of gas that is about half gas of unknown age (pulled it out of a junkyard around the time of my original comment around four years ago) and half tank of what is now about four year old gas. All E10 most likely. That truck is soon to get worked on to get it on the road (damn covid making it impossible to find parts) so I get to drain about ten gallons of some old gas to play around with. I'm only draining because part of the repairs is to replace the OEM carb with one that is less problematic and I don't feel like accidentally clogging it up.
@@NotSoCrazyNinja I was thinking if you do 50/50 shouldn't have any problem old gas with new gas
Properly stored gasoline stores almost indefinitely. Keep your tank full and you won't have any problems. Stabil is mostly solvent and a little naptha. They make a lot of money by propagating the myth that fuel goes bad. If possible store the gas nearly full in a cool place. Stabil works because when people use it they are paying attention and fill the tank up before storing it. Any small amount of varnish buildup is quickly removed by running some clean gas through.
We just started up a 1985 Buick Regal with a 5.0 V8, 12,000 Miles on the OD. It sat for 10 years with the old gas and started in only 10 seconds! I always thought this was a myth, but talking to a lot of old farmers, stale gas is a non issue.
I remember after getting my '51 Studebaker, I got it running on 35 year old gas.
Before anything, I pulled the drain plug on the gas tank, and nothing came out, so I passed it was empty (it wasn't). I added 5 gallons of gas, and it ran (really smokey, and smelled like deck stain).
I come to find out that the varnish at the bottom of the tank plugged the drain plug hole, and I had to dig around up there with a screw driver until it finally started draining out.
It took me longer than I would like for me to actually figure this out, so the varnish actually ended up sticking several valves.
I ended up having to take the head off free them up.
Anyone else come to the comments just to peruse for nay sayers?
Been subbed a long time 12volt, pleasantly surprised to find this vid of yours upon doin a search! Cheers
Gas goes bad but if it’s sealed in a tank it’s takes forever
Chain saw full of stale gas. 20 pulls won't start. 5 second spray of starting fluid into gas tank and sloshed it around. Started on second pull and ran strong. Don't waste money on high priced liquid either. Spray some starting fluid into your gas and keep going.
the main reason gasoline will go bad is exposure to air. in a sealed system the gas will get "stale" but tends not to varnish, if there is even a slight amount of exposure to air it will varnish badly after about 12-15 months. he talked about his dad always draining carbs after use and having varnish issues, thats because the carb bowels were left plumb full of sail boat fuel to act on that gas.
Using premium no ethanol fuel lasts a long long time. 7 years in the old car and still runs.
@@12voltvids I've seen gas that old still run an engine before. over the years i have taken stale stinky gas and laid it on the ground next to fresh gas and lit them up for comparison purposes, the fresh gas always lights easier. i'm not trying to get in an argument with you about anything but i know for sure that gas that is left in a fuel system for too long will varnish and destroy fuel system components. im glad you haven't had any issues so far but i would highly recommend that you replace that old gas with fresh.
i forgot, using non ethanol gas is better for longevity, and your fuel system must be sealed pretty well for your gas to have lasted that long.
@@jheetman the generator is empty now. The metal petcock corroded and fell off dumping what remained on the floor. The car will get some new gas added soon. It will be a project car once my son grows a pair and learns to drive. It was supposed to be for him but he decided not to drive. Some day he will grow up and figure it out that not being able to drive will severely limit his earning ability.
@@12voltvids my girlfriends nephews are like that... for me a drivers license =freedom. i guess i just really wanted to go where i wanted when i wanted.
So THAT'S why our old Honda lawnmower never had fuel issues with the old stuff sitting in it all winter! We never used fuel stabiliser but also never shut the gas valve off (not on purpose, just by chance) and I was scratching my head as to why so many people seem to be getting carb clogging issues.
Correct. And get this. The ethanol in gas will actually absorb water. This whole generator still runs I still start it up every couple months and run it for a good 15-20 minutes and I have refilled the tank a couple times as I burning off a little bit of gas every time I start it up and run it so I keep it topped up.
Lol, I had a 1988 Honda Accord 2.0 4 cyl Fuel Injected sitting since 2008, started it last time in the garage in 2012 after putting 2 gallons of gas. Last Month in August 2016, I tried to start t with a New Battery, wouldn't.
Turned out the Fuel Pump was Bad, from sitting it dried out and Rusted, wouldn't suck the fuel from the tank.
Also the Fuel Injector Gaskets, Rubber seals were leaking, replaced those.
Replaced the Pump.
Then put 2 gallons of Fresh regular, added some Octane Booster, Fuel Injector Cleaner and it Fired up, after idling shaky like it had a cold, once the new gas was flowing thru the system, the idle sounds Normal.
But I've still got a Better one.
Why did the fuel pump dry out and rot? It's not like gasoline is a lubricant for a fuel pump???
Was it an original fuel pump from 1988?
Nice bagger 👍 I have a '12 Electra Glide standard and for winter storage I put in a can of Seafoam, fill it to the top with fresh gas, then run it for 10 minutes.
I start the harley up every few weeks and warm it up. Over the winter the gas won't go bad in it.
This video was put up in 2014, I agree being 2022 now that ethanol is more damaging now than then..... I've been dealing with the damage to my parked projects lately. Never again parking anything for more than 3 months!
E10 doesn't do damage like e85 and fuel systems that are modern are built to handle ethanol
The gasoline in these devices was not 10 percent ethanol, but just gasoline?
I just bought a 2007 Honda Civic from my sisters friend he had it stored for over a year. I noticed a lot of trembling when I turned on the AC.. Alternator was the first thing that ran trough my mind. I was going to take it to Autozone so they could check it out the next day, but before the next day came I decided to fill her up more than half a tank. When I first got it was a little bit more than a quarter filled. I started to notice that my car stopped trembling when I put the AC I did no work on it at all only put gas is all I did and it’s not trembling at all. Can someone explain, please?
You had bad gas lol
gasoline is a natural detergent. Old gas has spent all its detergent properties. running new gas can clean out any dirt from old/bad gas
Gasoline also looses octane as it gets old. The old gasoline you had left in the tank had enough remaining octane to run the car, but the added stress of running the A/C compressor was enough to cause the engine to struggle since even as the ecu was adjusting the timing, AFR, the diminished octane wasn't providing enough energy for the demand. Added fresh fuel brought up the octane threshold thus allowing for proper engine operation even with the increased demand of having the A/C on.
I have often heard this said but have never experienced any problem myself storing fuel over winter etc.
Could it be that if the fuel tank it is being stored in has a very poor seal (i.e. a lot of the gas evaporates away when stored) this is what causes peoples problems?
If this is the case it may be more concern that there is a fire risk when storing fuel in poorly sealed fuel tanks?
btw - I know fuel tanks are never totally sealed but it could be the rubber seal around the filler cap is not working which opens it up more than it should
Dont believe him. Different engines handle having gas left in them differently. My toro snowblower will not start after gas is left in it for 6 months. 2 of the 4 yrs ive had it i forgot to drain the float bowl and it was full of corrosion which plugged the ports. I had to disassemble and clean. When i treated the gas for storage or drained it, no problem. Same thing with my yard machines lawn mower and log splitter. My 20 yr old snowblower seems uneffected by gas left untreated all summer. Follow the manufacturers instructions.
I agree Will. I could also be bragging about how I never stabilized my Suzuki outboard for many years but eventually the lack of care catches up and the idle gets rougher and it conks-out. I disassembled the the carbs (3) and cleaned out everything. The Mikuno carbs are very easy to work on but Not an easy job to keep the carb linkages in Sync. when you reinstall them.
I bought a motorhome that has over 100 gallons of gasoline in the fuel tank. It's such a tragedy though, because the gasoline is now GREEN from sitting for so long. I decided not to drain it because I have no idea what to do with that much gasoline. I'm not taking the motorhome anywhere because the transmission is bad, so for now I'm just going to leave the fuel in there.
Sounds good in theory, but what happens if the float sticks with the inlet valve open?
Not expecting an answer, but I know already; the tank slowly drains and the excess fuel floods the cylinders, weeps past the rings and fills the crankcase with gas.
Eventually excess fuel spills out on the ground.
When you go to start it you may find the oil level extremely high, and very thin, smelling of gas.
Even if you manage to start it by opening the throttle to allow more air in the flooded cylinders, the engine will continuously run rich and require WOT to start as blow-by from the crankcase increases fuel mixture, oh, as well as washing the cylinder walls of the oil film and allowing direct metal on metal contact of the rings, skirt on the cylinder wall, resulting in scoring and possibly seizing the engine.
But your carb is clean, lol.
Floats don't normally stick open unless they are left empty with the float down in the open position when the residue dries out. Also all carburetors i have ever seen have a vent at the top of the bowl to prevent a vacuum from forming. If the level gets too high from a stuck needle valve for example it will just over flow and gas will spill on the ground and evaporate.
Didn't think if that one did you ?
@@12voltvids OK so explain the crank case full of gas on a forklift left sitting for a couple years. Dino decomposition? God?
@@12voltvids So gas residue is the only thing that can plug the inlet valve?
I dont know if you're debunking any myths, but gas definitely does go bad. That doesn't mean it becomes inert. It will definitely burn, especially if its in a sealed tank, but it can also cause problems. I guess it just depends exactly what myth you're trying to debunk. Someone who says gas won't work at all if its old is wrong, but it should be avoided if possible.
Is my mechanic tripping if he said that my motor blew up from running on bad gas?
I know this is an old video but i have an 01 cherokee thats been sitting for 8 months with gas in it. Should i drain it and fill it with gas and an additive or am i in for bigger problems?
Took me 7 years to burn up that gas and replenish it.
I’ve had issues with some engines and older gas, what I do is if the tank isn’t full, top it off with fresh gas and it will likely do just fine. In my experience your lower or mid compression engines like most cars, lawn mowers, generators etc will burn older gas just fine. Your higher compression engines like snow mobiles, sport bikes, etc don’t fair so well with older gas.
It is true gasoline will last a very long time in a cool climate if it is in a well sealed container but I am from Arizona in the valley it gets over a hundred and fifteen degrees on average in the summer and whether you have it in a sealed container or not gasoline starts going bad here after about 6 months the temperature has a lot to do with the deterioration of the fuel the cooler the climate the slower it deteriorates same thing with motor oils types of rubber anything pertaining to petroleum it is much slower decomposing in a cooler climate here in Arizona in the valley we only get three years to four years Tops on a set of tires before they dry rot and blow apart.
I have a similar problem , half a tank of 2 year old gas and I can't syphon it out for some reason. Mitsbishi Montero sport 2000. syphone hose keeps getting stuck like 2 feet in. any ideas? HELP!!!
Yes that is the anti theft baffle in the filler designed to stop people from siphoning gas. So what do the gas theives do these days? The drill a hole in the bottom of your tank and now you are looking at a 1000 repair bill. That happened to my work truck. Boss was pissed.
@@12voltvids any way around it?
@@ver151set Thanks but I wound up giving up on syphoning it. I just filled it up with the best gas from gas station and all went well. it was riding a little rough on that 1st tank but no problems after that.
Probably need a new starter soon but it runs. Sounds terrible. I drain my tank run it until no gas is left in carb. When I go to restart it starts within 2 seconds.
Good Lawd!!!! I bet that starter was one hot bitch. If you shut the fuel off and run the gas out completely, you can get around the varnish issue. That T Bird ,with a little TLC, will be a bad boy.
Modern gasoline (minus ethanol free premium) has a poor shelf life. I did manage to start my Dodge Caravan with 5 year old 87 octane fuel in the tank but I added a bottle of "Heat" and 3 fresh gallons of fuel.
On year 6, the fuel finally broke down and the vehicle barely would start. I had to pump it all out. When I burned the fuel, it had a much lower flash point and smells somewhat like kerosene.
I had like less than 1/4 in my 2007 Mazdaspeed 6 and my car ran fine until after it got to 1/2 a 1/4 tank, it started misfiring when accelerating hard, even in neutral. I have to press the gas pedal lightly for it to rev because it's has a small turbo and it can generate boost even in neutral. I'm planning on putting in an octane booster, but since there is so little fuel and I'm still not going to drive it I might as well not bother.
Why would the fuel not run if you added 3 gallons of fresh gas.
I have a 1/8th tank of 7 year old gas. I wanted to add 10 gallons fresh gas and start my car. Thoughts
6:18 ya rev with it tappin that'll help 🤭
Gas and oil in there now is 8 years old, still starting and tappets still noisy. This one will some day be pulled out of the garage and given a tune up. I was hanging onto it for my son whom said he wanted it, and they decided he doesn't want to drive period.

That car is the last year that ford made the supercoupe 95. The paint is a rare ford color chemelian blue. In 95 ford only make 3500 supercoupe with auto trans and 615 with standard.

He got his learner's ticket at 16 never drive never wanted to learn and let it expire. So now he has to start over.
It won't work with the ethanol gas most likely. It'll eat through the fuel pump diaphram.
Never ever put ethanol in a carburated engine, even most injection vehicule don't recommended it (wear the rubber seals faster)
@@quentingence4278 ethonal is expensive and if you put 2stroke oil in gas then it solves the issue .
@@quentingence4278 um is ethanol unleaded? If not where is it bought?
um is ethanol unleaded? If not where is it bought?
@@ameerordimly1449 You are confused. The ethanol is already in the fuel. The amount of ethanol added to the fuel varies, anywhere from 5% to 85% ethanol depending on where you purchase the fuel. They fuel pump will have a label to reflect how much ethanol there is in the fuel. Cars that are set up to use gasoline only can tolerate up to 10% ethanol, but the engine will not run as efficiently since the engine is designed to run on gasoline (petrol) and addition to this, the ethanol added to the gasoline has a propensity to attract water from the atmosphere which can then contaminate the gasoline with water. If a vehicle is set up to specifically run on high ethanol blend, then it will not have problems running 85% ethanol blend. When you ask if ethanol is unleaded, there is no such thing as leaded ethanol, since ethanol is just a grain alcohol. Hopefully you understand now.
I have a 1976 Trans Am, Pontiac 400. Belonged to my Dad when it was New.
He stopped driving it in Summer of 1986. Reagan was still President. LOL
Hasn't been Touched or Started since 1986.
The Car is now Mine. And I want to see if I can get it to Run again.
The Fuel Gauge, reads Half Full. I wonder if it's stuck?
Did the Gas Evaporate in those 30 years sitting? Or is it still in there burnable? Was the Old Gas from the 80s better than Todays 10-15% Ethanol mix?
It's now October 2016, Can I just Add B12 or Acetone or Fresh Premium to the Tank and try to crank it?
Could it be that easy? or would the Fuel lines be gummed up, would the fuel pump even still work if I hook up a New Battery?
Did it start up?
Yes, update please, I am very curious of the outcome and the results!!!
4 reals did it start with that old ass gas?
Damn thing blew him to pieces! RIP Phenom!
Ah yeah!! She started up with nooooo problem!!! LOL
It started didn't it? And no priming required.
@Brady Mayer
I finially burned off all the old gas and refilled. Then the fuel shutoff broke and dumped a bunch of gas on the ground. So now it sits awaiting repair.
Straight gas doesn't go bad, but the Ethanol that they put in regular gas stations (up to 10%) does. In a car I don't know the consequences (especially considering modern cars' finicky emission equipment) but regular unleaded older than ~3 months just wrecks small engine carburetors.
What I do is just buy small amounts to use for lawn mowing at the start of each mowing season, and any I don't use before the lawn mower goes back to storage will be drained out and put into the car. As for the mower, the tank is emptied and mower run until it is empty (there's no gas shutoff on mine)
My dad used to do that, drain the tank, and then start it and run till it stopped and he still had to rebuild the carb every year.
It was the mechanic that told him to fill the tank, and leave the valve open so that fresh fuel would replenish what evaporates from the float bowl.
Been doing that since, and have not had to rebuild carb since.
In my current car, a Chevy volt, it won't allow the gas to age for more than a year. If you haven't put any gas in for 1 year it will go into maintenance mode, and run the engine every time you turn it on until you add some fresh gas.
It measures how much you put in, and if you only put in a little, then the timer gets only a partial reset. If you run the gas down and fill it up you get the full year. I finally ran the generator tank down doing it's monthly maintenence runs for 30 minutes every month, so I topped fresh as up last fall, so I am good again for awhile, but the gas in there by the time I refilled was 7 years old and still started fine. Lots of smoke when it fired up but it ran fine.
The thing is the Volt (and all other PHEVs) possess a special air-tight/sealed fuel storage; this is why regular cars can fill up by shutting them off and twisting a cap, but the Volt, i3 REx and Fusion Energi all require a button to 'depressurize' the fuel system before fill up. Heck, the gen.1 Volt requires 91 octane Premium because GM at first was concerned that the 1 year maintenance cycle would have degraded the Ethanol-rich 87 octane Regular that people will likely put in a Chevy.
Historically I did what you did when the 'full tank of gas" over the winter, but what happens then in the Summer was a full tank of watery gas and a carb full of crud that required the bowl, float and jet to be manually cleaned up. For 2016-17 I did the "empty tank" method and it seem to have worked.
The main issue with ethanol is just like any other alcohol, it attracts water. The climates that the gas is stored in will dictate how fast it goes bad. For instance, if the gas is left out in the open in a humid tropical environment it will go bad faster than if it was left out in the open in a desert. Once water gets into the gas, the ethanol that is in the gas actually separates and settles on the bottom of the gas tank or carburetor float bowl if the equipment has a carburetor. This would be seen as yellow or white goo that settles on the bottom of the float bowl. Once this goo buildup gets large enough, it will clog the ports in the carburetor and will require disassembly to clean.
Don't try that will a small two stroke. It wrecks the fuel pump diagram
I couldn’t listen to that starter gertting cooked
It's fine
Not sure what myth you say is busted. Gas certainly goes stale. That doesn't mean it is no longer flammable or combustible and I don't believe that's ever been claimed.
Your statement about the fuel bowl being replenished with 'fresh' gas is erroneous because the tank has the same stale gas as the fuel bowl. That incoming gas will also evaporate and turn to varnish and add to the varnish accumulation in the fuel bowl until the float can no longer drop.
As the gas ages it loses octane, it loses the ability to de-gum, and it will leave a sticky residue in the CC, on the valves, on the piston rings, etc.
When you start that car engine, you can hear the noise of the sticking valves.
Edit: Valves can stick closed and can stick open. The ticking you hear is likely the valves are sticking slightly open so there is excessive gap at the valve stem.
What I was referring to is if you shut the fuel off and let it run till it stops there will be a little bit left which will evaporate and leave a sticky residue behind that has now clogged the carb jets. When left on the fuel is replenished and not permitted to dry. Eventually it will go bad but it lasts far far longer than some claim. Years actually. My Chevy volt for example i use 1 tank a year. The computer at the year anniversary turns the engine on every time i drive after 1 year to burn the gas up untill i refill which resets the timer for another year. My dad used to shut the gas off o. His lawn mower and over the winter it evaporated from the carb and needed a rebuild. Same with his motorcycle. He shut it off and let the engine run till it stopped every ride thinking an empty carb was the way to leave it. Not!
He was always overhauling it. I have never had to do that. Mechanic told him to leave fuel on , problem solved. No gummed up carbs sitting over winter.
Bad gas can put deposits all over valves, ive seen them seize valves till it bends push rods
No that's over reving that bends valves.

I’ve always suspected the gas from Kroger was not as good as Meijer gas, perhaps it was because of the occasional surging, but I still bought the K gas using discount points to offset the over $5 a gallon fuel of 2022. My tank won’t hold the entire 35 gallon limit of the discounted gas so I fill a few portable cans to use later. Now I had just cleaned the old varnished gas residue from the carb passages of a pressure washer less than a month ago and used the washer for several hours on the fresh Kroger fuel but yesterday it was difficult to start and ran like crap when it finally started. I drained the tank and found the fuel was cloudy and a little yellow. As it sat, I saw water settling on the bottom of the glass container. That fresh gas is less than a month old. Sort of reminds me of the time I filled my tank at a brand new station that had only been open a week. The next day my car had the hardest time starting and when it did, not all the cylinders were firing. Eventually it smoothed out and I never went to that station again. As for your contention about over revving causing bent valves, my daughter’s Honda Prelude engine self-destructed by just starting it. Turned out the valves stuck open on her interference engine, which bent the valves when the piston hit ‘em…destroying the cylinder. The valve stem deposits were because of the fuel, but perhaps not because of old fuel since when I dropped the gas tank, the fuel looked like cola. I suspect somebody poured a 2 liter bottle of cola into her car. Anyway, I stumbled upon the video hoping to find a way to reuse old stale gas. I guess I’ll keep looking.
@@annettesurfer gas should be used up by the time it gets to be a year old. My current two cars are both Chevy volt which are the plug-in hybrids. The engines are seldom used on one especially. I can go in an entire year with the engine only coming on a couple times and a full tank of fuel after a year is almost full. The onboard computer keeps track of how long the fuel has been in the tank and at the one year anniversary forces you to use it. So if the engineers at general motors program the car to use the gas up after it's been sitting for a year that's a pretty good indication that the fuel will not be bad at the one-year point. So I think it's fairly safe to be fuel in for up to a year. the field in this generator was in for about four or five years and it started up and ran and I burned it up and refilled it with fresh gas. What I was getting at was my dad used to turn off the the petcock on his lawn mower and leave the engine run until it's sputtered out and stalled. He was always having to take the carburetor apart and clean it out because the small amount of residual gas that remained in the bottom of the carb float bowl with dry out and leave a sticky varnish mess that the next time you fired it up in the following spring it wouldn't run because the needle valve was gummed up the Jets were all gummed up. Started leaving the tank full and leaving the petcock open so the float bowl was full and never had problems down the road. Why because as gasoline evaporated from the carb fresh gas would replenish. The gas lines were always kept full of fuel and the needle valves and seats were always kept wet. That's the key don't let them dry out. If you drain everything and there's a residue left it will eventually dry out and turn to varnish.
was the gas ethanol gas, or non ethanol gas...thanks
In the old car non ethanol. In the gen it would have been regular.
Yea it’s true it was on the internet
You forgot to tell us what type of gasoline was in those tanks. Non-ethanol is day and night from ethanol.
Fuel line left on did nothing for you. Obviously the fuel was completely evaporated from the fuel lines and carb.
Tappets? LOL. Hydraulic lifter noise.
The old car has non ethanol premium in it but the generator has just regular gas with ethanol it it. The gas has not evaporated from carb. With fuel left turned on as it evaporated it is replenished. I start it every few months to birn off a little
It's best to keep ethanol-free gasoline in engines that sit.
sh*t that thing is loud, even for youtube video. i just bought a Champion today, 4500W peak.
In the beginning you said modern gas doesn't go bad as easily, but that's wrong. Modern gas contains ethanol, which will make it go bad more easily and make it turn into gel eventually. While, in the worst case scenario, gas can loose parts if it's quality after 3 months, even modern day gas will probably still work after more than a year... I have a little bottle of 10% ethanol RON95 (91 octane in the US) fuel that is still very thin and will probably still run fine in any car.
Also, two year old gas will probably not make a generator or lawnmower run much worse, but I wouldn't risk it in a car engine. It also depends where the gas has been. If it was stored in a plastic jerrycan for 3 years, inside, it'll probably still be fine. If it was stored in your fuel tank, in a car that sits let's say outside, yeah no drain that shit immediately
The length of time to get the generator to start was cringe worthy - I'd say that it probably didn't really hurt anything but still after the first 5 or 10 seconds I thought there's no hope for that starter even if it does start....
Generator is fine. It is always hard to start when it has been sitting for 6 months. Especially with old gas in it. I have burned all that old gas now, and replenished it.
I have 5 year old gas in a BMW motorbike, anybody has experience what to do? Keep in mind BMW is fuel injected, not carb.
Maybe your gas station happened to have less ethanol than mine... I could post a ton of videos of pulling fuel filters on RVs that sat for a year or less...
Wow how long did the starter have to turn that over?? Generators should run on much lower octane than a new car, so testing on a generator isn’t proof of anything...
New cars generally don't need much octane. With direct injection they will run on pretty much anything from ethanol to av gas.
5 years that battery would be DEAD DEADS DEAD
The gene gets run every couple of months for at least 30 minutes and the car battery goes on the trickle charger.
14 year old gasoline...no "stabilizer" and it still works well:

I started toke the gas out of my 91 ford f150 today because it set for 4 years put some in my lawn morwer runs just like new gas it was funny smelling but run just fine 10 free galins of lawn mower gas for me
Don't try that will a small two stroke. It wrecks the fuel pump diagram
