With a superior base oil (Group II+) and a custom blended additive pak (as opposed to a premixed one) why isn't Pennzoil the hands down choice over other regular dino oils? (5w30/10w30) I am not a Pennzoil bigot, I had always heard that Pennzoil sludged up engines.
I have been using Quaker State 5w30 in my 1997 Grand Caravan since I bought it (110,000 miles, 5000mi OCI) and am looking to change to something better. Pennzoil, Chevron/Havoline all look like fine oils but Pennzoil seems to be superior. I'm no oil expert and would like to know from those who are why would Chevron/Havoline (or other) dino oils be reccomended over Pennzoil?
