I just started and ran a 79 T-Bird for an hour and fifteen minutes with gas that was last put in in (I am not making this up) April of 2004.
Depends on how you get it out. If possible the tank should be drained and the lines disconected and flushed. If you can drain or syphon the tank on a modern fuel injected car the system should circulate the bad gas back to the tank in just a minute or two when trying to start the car. REMEMBER this will not work unless the tank has new good gas in it. The amount of bad gas in the lines should not hurt the new gas as long as you have a Half tank or more of new gas.
Could be water.
Normal Answer: They usually last around 1-2 weeks depending on how much you use the car. Silly Answer: If you fart in the car it might last for like 3 minutes dude its like totally rad man but be careful it can hurt
well it all depends on you. check it every time you do a oil change.every 3,000 miles look at the overfill tank. but it should last for as long you own the car. and if you want to make shore it does last, give it a radiator flush.
30 meters
The gas in a V8 car will last varying amounts of time. One tank will last about a week if you are only driving 30 miles each day.
It should outlast the car. Sometimes, there's a gasket on the underside that can go bad after a decade or so.
It depends on just how 'bad' the alternator is, but generally, not very long. You can actually drive your car until there is not enough electrical charge to spark across the spark plugs, and your car just stops, unable to start again.
Audi is a pretty good and long lasting brand of car.BUTIf you want a car that will last the longest than you should buy a Toyota. they have good mileage and will stay in shape for a very long time. And plus they have one numerous awards for such topic. So if you are looking for a car that will last long a Toyota is for you.I'm not saying that Audi is a bad brand all i am saying is that toyotas will last longer.
get it all out empty the fuel tank put good gas in the tank and crank it until it starts
it depends on the car
I used to be a firefighter and we would throw our gasoline out after 90 days. Gasoline starts to go bad after 30 days. I do know that the scent changes when the gasoline no longer becomes usable. If you use a fuel stabilizer it will last about 6 months.
