Best race oil.
This is the best oil you can get for what it's intended for, I used to use it for trackdays and street riding. Now I just use it for the track. It is a RACE oil, ya sure you can use it for street too and the oil itself will stay good for a while, but the detergents and additives break down real fast like after 3 trackdays or a race weekend. After that it basically turns into regular oil. So I change it out to the 7100 in between track events. This stuff is awesome when going to 16,000 rpm on my r6 anything other than that 7100 is best for aggressive street riding.
