What engine oil do you use in your gas E70?

[fast4d]

N62TU 4.8i with 110k miles

so cal coastal weather. temps range from high 30s to 90s

Rotella synthetic 5w-40

Mann or mahle oil filter

ALL factory recommended drain interval

don't need no stinking additives....until the valve seals go!



I've been using rotella for a long time. 4.4 X5 from 60k to 170k and now the 4.8 since end of free service.

no sludge. you have to make sure crank case is vented and oil separator not clogged so moisture has a chance to evaporate

this vehicle has plenty other things for me to worry about!
