I use the full synthetic after 2k miles on my busa. I am using the car mobil 1 oil 15w50. I used this in my last 2 bikes no problems....I put 24,000 on my fzr600 and their clutches are week and only replaced the plates once, cbr900 rr 12,000miles and no signs of slippage, and my busa with 4400 miles 2000busa, no problem so far, My friend has spoken to the mobil rep before and he stated it will work fine....My friend has 44,000 miles on his gsxr1100 89' and never had to replace his clutch, nough said....this oil rocks.....Bye the way we ride hard and not just cruise on are bikes to give you an idea. I ride hard and keep the revs up there on my normal rides....I try not to ride around town and try and find curvy roads in florida. I do ride above the average rider in my groups...a group of about 5 leave people behind usually about 5 minutes we wait up when we go through are normal riding routes. 2 out of 5 race expert level an 1 amatuer. I am going to race next year on a gsxr750 or an R6...$$willing....
