will send off 2 samples to Blackstone Labs. One sample will be the used oil from last year and the other will be a virgin sample right out of the bottle. Both are Redline 30wt race oil, I'll post the results when I get them.
I'm more interested in the clean oil and its amount of Zinc.
I sent off a sample of the truck oil last year and it came back that the engine was in great shape!
