Here is Blackstone's report on my 1997 BMW 328i. Car has 130k miles, Mobil 1 T&SUV 5W40 was in there for about 10k miles. The car has been on a steady diet of Mobil 1 since around 45k miles, usually changed every 6 months or every 7-8k miles. 15W50 red cap at first, 10W30 the last two years or so. And just when I think I have found my ideal oil with the T&SUV, they pull it off the market
Oh yea, I pulled the valve cover just for curiosity and everything in there was spotless. Zero gunk or varnish what so ever.

Comments from Blackstone were basically they couldn't believe the engine had 130k miles since the wear levels were so low.
