I have a 2004 Crossfire. I just found out oil changes are like $75.00 and I can only get special synthetic Mobil 40 oil and if I use anything else it voids the warranty. My question is if I get a regular oil change will it mess up the car. Also do I have to use only PREMIUM gas and would putting in the lower stuff mess up my crossfire?

 

please direct all your questions to the dealer, as far as the fuel ,the car is designed to run on 92 octane,or better.anything less and your car will ping or diesel when you turn the car off or try to take off.as far as the oil goes try wal-mart ,they sell synthetic oil,at a very sensable price...........
