deisil in gas with older cars will work to a point until too much of course ie pingin etc . on the new fuel injected cars things seem to be a little different . the ability for them to handle a differnce in fuel is less. the just wont run or the computer mgmt fiddles with the engine until it shuts down.
i have handled a few fuel misdelivery claims at gas stations and thats what i have found
being fro the farm i used to always but a galllon or more every once in a while in a full tank as its supposed to clean the fuel syst as it supposed to have high detergent factor.
did that one a long time agao with my wifes fuel injected cavalier and it just would not hardly go . i think i put a little much in but it still should have run.
