Background:
When I got the coach about 8-1/2 years ago (66,000 miles), the PO told me he was using some sort of Walmart 20W50 oil. Being a big fan of Castrol GTX 20W50 myself, When I did my first oil change, that it what I used. After reading about the ZDDP concerns, I did some research and switched to Valvoline VR-1 20W50 and have been using that ever since. The coach now has just under 100,000 miles on it and the oil pressure is good (according to the suggestion of a stock gauge) and oil consumption seems to be at an acceptable level (on the just completed round trip to Las Vegas, about 900 miles, it used one quart).
The coach now has almost exactly 3,000 miles since the last oil change and I am considering changing to Rotella 15W40. The reasons are; Price of the oil (VR-1 is about $6.00/ qt) and a concern, also read about on this forum, that the heavier weight oil might be hard on certain internal engine parts (oil pump) at start up.
I am interested in opinions about whether I should make the change or stick with what has worked for the last 34,000 + miles, and why.
Thanks guys,
