Here's my oil philosophy for what it's worth. Use regular high quality oil such as Valvoline and add Camshield or other source of ZDDP. Regular oil has the right amount of detergent. Racing oils have less or no detergent and diesel oils (Rotella, etc) have too much detergent. My philosophy is just based on what I've read and heard over the years that makes sense. I'm no expert.
