Same here. I've been using Rotella for the past 5+ years. I read somewhere that diesel oil will supposedly gum up an engine over time. Well, I've had my motor together for almost 11 years and have over 40,000 miles on it. A couple months ago I pulled the valve covers off for the first time, and they looked beautiful on the inside. Just a light film of oil. Before running Rotella I ran Valvoline. I'm gonna keep using the Rotella for as long as I can.
