I would also like a copy of your results if you wouldn't mind. I am so unsure of what type of oil we should be using. We are currently using Mobil 1 0W-30. Since Mobil 1 has a low zinc/phosphorus content, do you guys think I should be using a zinc/phosphorus additive?

I think the key point is yes unless you have a roller cam, which in theory doesn't need it as much. At least for the street cars. What the effect of the zinc/phosphorus is on the rest of the motor is a question is a valid one, and not something I had pondered till just now. Perhaps there is a benefit to running it in all the motors.
