(I don't mean the milliseconds after a spark in a near-stoichiometric mix) I've had a car sit in the garage for 8 months with a near-full tank and it ran fine. Or is the car's fuel system simply "too tight" for it to be significant over such a period? -- /"\ Bernd Felsche - Innovative Reckoning, Perth, Western Australia \ / ASCII ribbon campaign | For every complex problem there is an X against HTML mail | answer that is clear, simple, and wrong. / \ and postings | --HL Mencken

(I don't mean the : milliseconds after a spark in a near-stoichiometric mix) I think that the term must come from the likes of 2 Stroke mixes where the fuel most definitely "Goes off" Normal petrol I've used after a 2 - 2 1/2years in a tin and it was quite okay. Admittedly I used it in an older carburetted car but still, worked fine. : : I've had a car sit in the garage for 8 months with a near-full tank : and it ran fine.

I've used 2 stroke fuel in my boat that's been sitting in that tanks for more than 6mths and not noticed any problem but a mate went to use his boat after it had been sitting used for about 12mths and it wouldn't start, he took it to get it fixed and all they did was drain and refill the fuel tank and it started and ran perfectly. My 2 stroke is mixed in the tank and his is oil injected so its straight petrol in the tank. Daryl |
