So, mostly freeway driving with lots of long trips and at least one steep grade along the way (the grapevine, north of LA) The truck will not see much, if any, cold weather use. Mostly SoCal weather.
I know little about diesels as this is the first one I've ever owned. I'm busy doing my research on maintenance, etc. and thought I'd ask the folks here for their recommendations on what oil regimen to start with. I plan on keeping this truck for a long time (at least 10 years), so would like to institute good engine hygiene up front. Manufacturer recommends 5w-30.
Suggestions, recommendations? Thanks.
The Dmax engine is notoriously easy on oil. The type useage you state is well within the abilities of conventional oil.
M37Charlie is correct; only two reasons to run synthetics, and if you don't find yourself in those, synthetics are a waste.
There are some very telling UOAs from me and others in the UOA section. If that won't convince you, nothing will. Under "normal" circumstances (non-extended OCIs and temps above -20 F) today's dino oils do very well indeed.
My recommendation is to use any CJ-4 15w-40 or 10w-30 rated oil you find on sale, because it will mean much more to your wallet than it does your Dmax engine.
