Question type: General

Dumb question but what kind of fuel does the 500x
take? I've read it needs premium but is that really

4 Answers


It will run on regular fuel but performance will be reduced, the computer will reduce timing advance as you drive cause regular fuel will tend to ping at lower advance than premium fuels. So lower performance and possible less MPG.

Thanks for the answer. Guess I'll be using premium! $$$


Top tier fuels are the best, but if you can't always find any then put a bottle of Techron in the tank every other fill up, this stuff really helps keeping the fuel system clean, I have been using it in my rigs when it fixed an injector problem way back in 97. So far none of my vehicles have had any fuel pump or injector problems.


Per the owners manual, if you have the 2.4 liter engine, 87 octane fuel recommend. If you have the smaller turbocharged engine, 91 octane recommended, 87 octane acceptable.
