Is there any reason to go with the CAT oil over the Rotella? I know Chevron manufactures the oil for CAT to their specs. I have access to the CAT oil at $27/gallon or I can go to Wally World and get Rotella for $15-$16/gallon. If there is a compelling reason, I'll buy the CAT. The engine is a 1996 Powerstroke and I live on the southern shores of Lake Erie, so on rare occasions we may se single digits in the winter.
Thanks!
