I have a co-worker that drag races somewhat competitively drag races motorcycles. He went up to the super gas class this year. He was in a street class last year and I believe took second overall. I have never seen a UOA on a dragbike before so I thought this might be of interest to everyone. He had the motor for this bike rebuilt before the start of the season and was wanting to find a way to not have to change the oil after every competition or test and tune and decided to use Amsoil and see how it would hold up. Based on the UOA it would seem it did well, though as I mentioned, Ive never seen one on such equipment before. He's got three scheduled competitions left and was looking to maybe being able to go all year without having to change the oil or at a minimum, just the filter.

He's also running 110, 113 or there abouts, octane fuel which I believe accounts for the lead reading. That aside, I thought that the oil did a pretty good job but I would certainly like to hear from everyone else.
