I recently picked up a Yamaha R6 which has a "supersport" build engine in it. Basically it's a blueprinted & balanced factory build with a lot of head work. Engine redlines at 15,500-16,000rpm. The builder recommends Motul 300V 10w-40 and a K&N KN-204 filter. However, as much as they know about engines, I'm sure there are some here that know more about oil. Motul is always a safe bet, but it's certainly pricy!
Before anyone jumps on me, yes, road racing is expensive. $60 oil changes every weekend are inexpensive compared to the $400 of tires, $100 of fuel, and $300 of entry fees I'll be dropping.
BUT, with such a short OCI, if there was a less expensive oil that still protects the engine as well for the ~100-200 miles it's going to be in it, then I'm all for it. It's the same reason I'll be running pump gas in some classes vs. the oxygenated MR-12 - Why spend the money if it's not needed?
From the searches I did today, seems like some might recommend Valvoline conventional 10-40 or Rotella T5 15-40, but I'm open for suggestions.. It probably doesn't need to be said, but after being warmed up gently, I will be beating on the engine and clutch like it owes me money.
