Fuel Additive/ octane boosters???
My car is at 30k miles and I've never used any sort of fuel additive or octane booster before b/c I wasn't sure if it would do more harm than good. I also use full synthetic and great oil filters, so I just figured I was doing every thing I needed to do... can someone please let me know what is a good product to throw into my gas tank that will help my engine/gas mileage? Thanks
