Dang, reading this thread is a bit unnerving. I use 87 octane in my car. Would simply going up to 89 offer any protection? Also, what's the difference between GM's Dexos oil and other synthetics? Would I be ok using Mobil1, Pennzoil Platinum, or Valvoline SynPower? Or should I just stick with Dexos? I want to do everything I can to prevent a failure from occurring.

Good to know. So as long as the oil shows the Dexos spec and is full synthetic, I'm good to go? I know there are some synthetic blends that are Dexos approved, but I plan on avoiding those. I'll also hop up to 89 octane from now on.
