Just wondering if I should use premium 93 gas, or 87 regular. In my owner's manual it says that the car is built to run on 87 gas, but you can put premium 93 in your car if you want best performance. Should I just pay the extra money to put better gas in my car? thanks.
Compression ratio is 90:1, and It has a 3.0 V6 engine in it.
It doesn't say on the filler cap what the recommended Octane is, but in the manual it does say that 93 premium is recommended if you want best performance. So I guess I could go either way.
