Best MOTOR OIL test web site ever?
I've been reading about various oils for over 25 years and have never shared a web site or document other than my own UOA's until today, when I came across this web site. WOW! It's a long read...vario...

It kind of supports my totally informal results from a couple different oils I tried. Both Castrol Diesel oil and Rotella Triple T are rated further down the scale than Delvac 1300. I send in a sample from my oil changes on my Cummins and the reports when I was using those oils were less than stellar. When I switched back to Delvac, I've had nothing but glowing reports.
