What happens if you put the wrong kind of gas in your car?

Like if your car takes the low grade, and you put high grade in it, what happens? I've wondered about that for years, but I've always been too embarrassed to ask lol.

  • It won't do anything. Some people believe that the higher grade gasolines will make your car run better, but that's only true if they call for the higher grade gasolines. If your manual says 89 is recommended, there would be no reason to go any higher.

  • If you put in a higher octane, you should get better gas milage in general for well tuned cars. If you have a "performance" engine that "requires" high octane and you put in 87, you will get crap gas milage and over time, you could have engine build up.

    Other countries have different octanes than the US but the same engines.

  • Depends. Diesel is bad. There is much difference between 87 and 89 though.

  • normally it doesnt really matter as long as it is gasoline and not diesel unless you have a car that requires high test fuel. Hubby has a sports car and if you put low grade gas in it, it drives like crap...I always thought he was crazy and just "had" to have it but I put low grade in it one day and could definately tell the difference after driving around for a little while.
