I have never head of anyone having a problem using premium in a newer vehicle. Older cars had issues with it, but you shouldn't see a problem.

Try this. Run one week with one type and one week with another. If you see no difference in mileage/performance/overall with the cheaper gas, use it.

I would suggest that you ensure you are doing regular tune ups and maintenance and to use a fuel injection cleaner from time to time with the cheaper gas.

I've wondered the same thing, and surprisingly enough the answer was in the users manual. regular unleaded. they've also got the answer on their website. Although the premium couldn't hurt (i'm not an expert so dont hold me to that) it's probably better with going the reccomended grade.
Hope that helps.

it does'nt really make to much of a difference what grade gas you use , like matada said if you are using regular i would keep an eye on your injectors. A lot of times the higher grade gas you use the better performance you get out of your car, but with a car that is 120hp using 93oct you are not gonna see huge difference.

Higher octane gas is used in vehicles with high compression, say 9.5 and up and vehicles equipped with a turbo or supercharger. Octane is used to keep fuel from exploding when compressed. The explosion is refered to as knock or pre-detonation. You car will run just fine on regular unleded gas. I recomend using z-max engine treatment, they have an oil, gas and transmission additive. Works great to clean the fuel system

definitely use regular, premium is a complete waste of money on your engine.
