Just Got a 2010 touring 370z and had a couple questions.

The ECM will pull timing if it detects knock, so, unless you are running really low octane, you shouldn't do any serious damage ... but why take a chance when the difference in price is pennies?


As long as you stick with the major brands, the condition of the stations' tanks and other pumping equipment will have more to do with the quality of gas than the signs out front.
