Now that I'm off warranty I can experiment with oil. Got about 2k miles on my experimental winter oil mixture; half Redline 40W race and half Redline 5W-30 street. I'll send a sample to be evaluated at around 5k miles. I'll change it at the mileage Blackstone recommends.
No, I can't say that the thinner oil helped the engine's efficiency. Thought I saw a significant improvement after the oil change, but it has since settled back to roughly the economy I was getting before ... 20 - 21 mpg on the turnpike at 75-80 mph.
