Patrick (Cosmic C) - you certainly know your oils. This is not meant to start an argument with you and I would not dispute any thing you say, but while I have not had the formal education in oils you have, I base my opinions on my experiences.
My last engine failure was in 1974 on a 1972 International Scout. That was the year I started using DELO400. The Scout had 33,000 miles on it and it had a bad clicking noise in the engine. The dealer told me I needed an engine rebuild and it was 3,000 miles over the warranty. A old oil man suggested I use DELO400 in it and drive it until it quits. 110,000 miles later it was still going when I sold it.
My vehicles are run hard and put away wet. I do not baby them. The last vehicle I sold was a 1992 Jeep Cherokee 4 L. I towed a flatbed trailer loaded with lumber weighing 6500 lbs from Olympia to South central Washington several times a month. The Jeep spent a quarter of those miles on rough logging roads. I changed the oil in it, between 7 and 10,000 miles.
As I stated in an earlier post, 300,000+ miles is not uncommon for me to put on a vehicle before selling it. I consider it just broke in at 150,000 miles.
When Mobil 1 or some other kind of oil will give me better service than that, I will think about using it.
