RE: Regular vs Premium Gas

I own a 2003 3.8L SS, I use to run the expensive stuff till the PPG went to $2.00. I did notice a slight gain in power when I did run it but I found the extra expense not worth it. I run the mid grade gas now.

RE: Regular vs Premium Gas

Yes you will notice a difference in performance. I use to have a 1992 Ford Explorer. I started with reg. gas and switch to the premium. I noticed that the engine smooth out alot and got alot better fuel mileage. The only draw back is premium is expensive. You might want to try Outlaw Fuel Injector cleaner every 3000 miles. I dont care what anyone says.......that **** works. Might be expensive but it works damn good. I think I pay $10 for one bottle.
