Is 30 weight oil still the best to run in the stock engine? If not?
Thanks |

Stock /6, I used to use Castrol GTX 20-50. Been using Shell Rotella T 15W-40 'Triple Protection' lately on advice from another board. Is it not as good as it was (ZDDP?). |

Is it not as good as it was (ZDDP?). Castrol GTX is junk. I used it as my first oil post-6 conversion since it was cheap in case I needed to pull the engine back out. But did a bunch of research for my first oil change and will never touch that stuff again. Running VR-1 here as well - the ZDDP numbers are pretty solid for 20w50...Advanced has it for $6/quart which is about the same price as Mobil1 at Wal-Mart! |
