I just bought a 2003 Matrix XRS, only to find out after the purchase that it is recommended to use premium gas in it (It seems the dealer had the sticker on the window for the regular Matrix).
I'm not looking to race anyone, so I don't really care if I don't get the performance out of the engine that I should.
I'm looking to make sure I don't destroy my engine if I use Regular gasoline in the XRS. Can I put Regular in the car without a damage worry? Also, how much do you believe my gas mileage will drop using Regular vs. Premium?
Opinions, thoughts, and comments are greatly appreciated.
