This guy is a serious competitor in drag bike racing. He took second last year, I forgot the class name. He bumped up to the Super Gas Class this year and I believe is third in points. I went last weekend and got some shots of him doing some test and tune runs.
The high lead is from the leaded fuel (race fuel) that he uses so that is not a concern there. Given how hard this bike is run, the oil has held up EXTREMELY well. I fully expected to see some severe fuel dilution, and with that being absent I think he can go the entire season with no oil change whereas last year he would change it every other race. His silicon is high because he runs no air filter and I thought it would be higher than it is so apperently the oil is doing its job in keeping most of it in suspension to be pulled out by the oil filter.
I do think I will have him change the oil after his next competition just to be on the safe side. The oil has sheared back just a tiny tiny bit into the high end of a 30W oil which I also would expect with the hard runs. I do believe, though, next season I will have him go the whole season on one oil change, the oil is still in very good shape.

To be honest with you, I dont think it will. The oil has held up way better than I expected. I totally expected some fuel dilution which would have caused the oil to be used up much faster. With that absent and the additive package and TBN levels where they are, he could go the rest of the season.
That being said, the oil is cheap insurance and it aint going to hurt anything to change it out early. With his Oxidation and Nitration numbers where they are the oil is eventually going to take a hit dealing with that. If it were my bike I would go another three or four races and do another analysis, but since Im sponsoring him Id rather be safe until I do have a few more oil analysis to trend some data.
