Does anyone use Rotella T-6 full synthetic 5W40 motor oil in their RV? I have a 1994 Chevy 454 with 50K miles on it. I use Rotella T-6 in everything I have and was getting ready to change oil in...
I am the OP. I was pretty sure I would be OK with the Rotella 5W40 Full Synthetic since the auto parts stores said they could not keep Motorcraft 5W20 Full Synthetic on their shelves, they said all the auto repair shops and used car dealers bought it up to go in large engine pickup trucks. mtnman
