Does petrol go "off"
Parked my wife's clio up two years ago.
Killed the battery by letting it run flat.
Tried jump starting it yesterday and it spun over OK, and had that sort of vibratoin that makes you think it's about to start but it just wouldn't
Wondering if there's any truth in the tale about petrol going off and if so how long does it take?
Havent checked for spark or anything else yet, and might try some easy start.
Off the Xmas card list
I've had it last as little as 3 months. It's the light ends that start the burn that evapourate . Get a gallon of fresh petrol and use a splash in the inlet to get it going and then add the rest to the tank to give it a chance.
Yes, it goes off.
When I put my lawn tractor away for the winter I add fuel stabilizer, plus I always mix it in the fuel for my generator, which is only used maybe once every 2 years when there's not enough sun for my solar panels.
As above, it's rated at 6 weeks.
A topup of a fresh gallon in the tank will revitalise the old fuel, but as Kev says it will need fresh fuel in the carb/inlet to get it started.
on the low down
iv washed petrol before now, to stop it going off
its the ethanol that attracts water via moisture in stood tanks, so you need to remove the ethanol.
easy job, get a demijohn or large glass jar
poor in 50mm tap water
poor in your fuel
stand and watch it settle, and notice you now appear to have more water
poor neat petrol into can, avoiding adding the standing water at the bottom.
one day i wil wake up and i'll be dead!

There may be an issue also with state of tune of engine. My Riley with approx 7:1 compression, adjustable advance/retard, always seems to start even where sometimes I've left it for months. What I have found is that it seems to evaporate quickly eg a little left in the lawnmower has disappeared by the following season.
I used to think the gas got boiled evapped off my Edelbrock V8 chevy mill.
But if I go backa day later the gas is still there and it will start first go.
Leave it a coupla weeks and it needs 5 cranks to refill the bowls - so it aint the heat boiling it off.
It's thirsty so gas doesn't hang around 3 months
When hot weather it goes off even quicker
Thanks for your help folks.
A squirt of Easy Start down the inlet manifold and a jump off the Daily had the old girl started in no time.
