I think there is an allowable range of viscosities that can be considered a 20, a 30, etc., and it's possible that the upper end of one range might be very close to the lower end of the other.

I think it's evident that maybe it's not as critical as many of us try to make it -- including me. Otherwise, how would so many people second guess the manufacturers and use thicker than suggested oils for decades with no problems?

At least Yamaha give us a range.

Just keepin' up with traffic, Officer.

So reading about synthetic oil and trying to compare oils I find that some oils use the words “100% ester”. I realize there are no standards for synthetic oils in the US but does 100% ester imply 100% synthetic base? And what the heck is 4T? Some oils are 4T some are not even some Yamalube full synthetics are labeled 4T while others are not. From what I’ve read I believe Motul uses a vegetable oil base? Amsoil and Motorex seem to be more elusive as to what base stock they use. I do know that from personal experience Motorex turns dark faster than other oils. I have been told that may be a sign of higher detergent content but I have no idea if it’s true or if that’s a good or bad thing. I know that at the end of the day good oil is good oil and there’s very little to be gained between brands but it is interesting to try and compare and frustrating as **** trying to get info from the manufacturers. If transparency is a good thing the Motul seems to publish the most info about their products.
