Oh Boy, you'll get alot of debate over this one. Especially when it comes to pre-firing caused by lower octane and the engine parts that will fail with repeated pre-firing... Get ready for some serious engine repair at 50,000 +/- miles.
Post your VIN # in the forum so we can track the life of your engine after you sell the car... And hopefully warn the poor bast*rd that buys it...
