I have a BMW with the N52 (2.5L L6, NON-turbo, NON-DI) pulling a camping trailer. 65k miles on engine. Well maintained. Good working order. Hardly any consumption.
The car will be used to tow a camping trailer across the USA on a trip this coming winter. We will cover approx 20,000 miles overall. The engine is somewhat underpowered and is forced to run in 5th gear on flat land, 4th on inclines, and 3rd when climbing any grades. 60mph max, usually 55mph. Somedays it will be running like this for 10-15hrs per day. Very stressed motor indeed.
I'm thinking that a heavier oil would best be suited for this application. Maybe an HDEO. Up to now it's run GC 0W-30 exclussively. BMW 10W-60 maybe?
Being away from home, I would prefer to do an oil change at approx. 6-10k miles and no sooner.
Price of oil is not really a consideration. What are your recommendations?
