quality premium product designed specifically for wet clutch motorcycle engines. Meaning a 5W-40 or 10w-40 synthetic blend or a pure synthetic oil. The pure synthetics flow better... plenty of test data as proof of that... reason each molicule is identical to the next. The pure synthetics don't break down or get "sheared" are quickly as blends or dinosaur oil. A recent study tested various oils and found that most dino oils were 50 percent sheared by 2000 miles... which means they were totally worn out. The pure synthetics tested under the same conditions in the same engines were only 8 percent sheared at 2000 miles. The "shear" strength is the ability of the oil to keep the metal to metal parts separated from each other.
You be the judge of what you wish to use but be aware no blend or dino oil is as good as base one synthetics.
If you pm me I will tell you which oils where tested. I will post a copy of the actual report if I can find it in all this mess I have laying around. I did have a copy on my computer but the hard disk went to lunch and didn't return. \ken
Ken- I agree with your synopsis on dino vesus synthetic but if you have the same report that I do, it was paid for by Amsoil and I won't say it is invalid, but it was not purely independent.
Not a flame war at all , but I wouldn't trust a report paid for by Mobil or Castrol either. A completely independent report , devoid of ANY funding by an oil manufacturer or marketer would be the best. (If thats what you have I apologize ahead of time) .
