ok 2 things, first,
steve, you are recommending an oil 20w heavier than nissan recommends, so surely something 10w heavier than nissan recoomends should still have a higher oil pressure than standard, so his oil pump may be stuffed if he is getting low pressure with that. (and yes i know the stock gauge isn't reliable)
secondly you say mobil 1 is crap for RB engines. does that include mobil 1 15w50? as it is the same weight as the motul you have suggested?
now i don't care whether people use motul, mobil 1 or oil out of a deep frier at their local take away shop. i have never used mobil 1 and probably never will. but i want to clear up whether you are saying that mobil 1 oil is crap in general, or just the 40w oil is too light for an RB.
and if you are saying mobil 1 is crap no matter what weight, please specify why. if you have had an engine faiure while running mobil 1 how can you say that it was definately cause by the oil and not the fact that (i am just using an example, not saying this happened) you were sitting on the limiter when it popped.
