Re: Misfire!
Update! I pulled my spark plugs and they look like this! Is that oil? I have a feeling this isn't normal.
FYI I've never used any octane booster, but I am guilty of using fuel injector cleaners like lucas, MM oil (one tank) and other additives to "clean up" fuel lines. I use Mobil 1 or K&N oil filter with Castrol synthetic or Mobil 1 Synthetic 5w-20 with an occassional Lucas oil stabilizer. I also have a JLT RAI.
