We travel primarily in the west coast and never exceed the temp range the 10/30 would cover. We have 120k on our coach and have replaced the Huei pump once along with a couple of injecters.
Has anybody made this change and what have been the results?
Who is the "Cat" that recommenced switching oils?
For the CORRECT answer call the Caterpillar RV Hotline, (877 777-3126) with your engine serial number and ask...(IMO nobody
knows your particular engine like the manufacturer).
