that is the test report I have yet to see.
You can put a motor oil thru all kinds of testing protocols, and see how much the viscosity reduces, see if the additives remove carbon from the engine, and you can test filters to see what size particles they let thru
but.. over the life of your MC engine, does that indicate the motor will last longer? I have never seen that data.
The SAE standards for motor oil indicate it will perform and keep its characteristics for its intended use at the temperatures you would expect to see in your engine. So if the oil has the SAE lollypop, then it will do what its suppose to do, whether its $2 or $10 a quart. That is what the standard is for.
One of the great things about a motorcycle from an engineering perspective is it 'can be' an ideal one person motor vehicle: small, light, maneuverable simple to operate and maintain, AND inexpensive compared to a car or truck. If you have to use premium gas, and $8 oil, and buy expensive filters it defeats that inexpensive appeal.
We already have to bite it on tires, because MC tires are not made in the quantity like car tires, so you cannot goto Walmart and get a motorcycle tire for $30 and have it installed for $10.
Personally it will take me 20 years to put 100,000 miles on one motorcycle. I think by then I will be ready for a new one.
(and by "new one", I mean another bike that someone bought new from a dealer, hardly rode for a few years, and then was happy to sell for half what they paid for it).
