There was post about this oil in the internal engine forum. I decide to try the 0w 40 mobile 1, and increased oil pressure at idle from the mark below 40 to the mark above 40 psi. I did this to see if it would quite the start up, so far all i can really tell is the oil pressure is better. Just thought I would let everyone know my results.

 

I wouldn't bother with 0W40, theirs alot of additives in that oil to make that large difference. 5W20 is getting alot of attention from OEMs at the moment.
