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...
back in the early 60's my dad went from Ohio to Kansas he had a 57 Olds when he left he put in STP oil treatment because it was to be good for your engine,it cleaned out all of the gunk and when they got back it smoked more than a Hippy in the 60's just a thought
