My take on oil is this, right, wrong, or whatever...... The longer it in there, the higher quality. The harder I run it, the higher quality.
How often do you hear of a motorcycle engine failing because the owner ran average oil instead of the Super Expensive Over Kill oil?
I ran Rotella in my 919. 87 octane, Marqthon or BP, where I could find it. I changed oil every 3000 miles because I run my stuff fairly hard.
