I was looking for articles but couldn't find anything, still learning to use the search function so it's probably just me.
Anyway in my constant thinking I've started pondering what kind of oil to use.
I have at my disposal a lot of BMW 5w30 full synthetic oil. Its pricey but I know a guy I've used it in my other vehicles and have had no issues. The API rating is SL/CF which means that it means the standards for a diesel of my model year (1990).
Is 5w30 ok to run year round in our trucks? It gets cold in the winter (below freezing) and hot in the summer (couple days at 100 deg last year). Just want to make sure before I do something dumb
if you're gonna be playing with oil that thin, it would be wise to have a real oil pressure gage so you can keep a close eye on it in different weather conditions. i wouldn't try it when its hot outside
my van, 87 e350, 6.9 NA, c6, 3.55s with a powertrax locker. built out with toolboxes and onboard 120v power and compressed air powered by twin 3g alternators
I am using SAE30/10W30 synthetic year round, will be taking used oil analysis and no plans to ever change the oil, Only topping off and changing filters as I drive my truck.
Engine is new with about 5500 miles so far.
I am doing it not theorizing about it.
Its my understanding that moble1 full syn 0-40 is a thick oil that mecedes use's in all it,s new cars...it has a mecedes part # on the lable, I may try it after I install real pressure gauge, to monitor things,
