Question

What happens when you put the wrong type of gas in your car?

Answer 1

by wrong type, do you mean octane rating?

If you put in premium and only need regular, no problem

If you did the reverse, I wouldn't make a habit of it, but one tank won't kill it - you could consider some octane booster stuff to reduce detonation (although your car might handle it ok depending on what it is and what kind of sensors and computer controls it has)

If you put E85 in a car that isn't designed for it, you need to get it out somehow and replace it with regular gasoline. E85 is very corrosive and will do damage to your engine and fuel system if it was not designed for it

Hope this helps
