And not a single JASO MA certification mark among them. So, it is just their unsubstantiated claim that these products "meet or exceed" those standards. And again, since API no longer certifies motorcycle oils, and that the former API motorcycle standards are now obsolete, you'll likely not see an API donut on a dedicated motorcycle oil. The JASO mark is about all we can hope for.

Keep in mind the corporate lawyers waiting in the wings at the motorcycle manufacturers just waiting to say that your oil related property loss was due to using non-certified oil. It could happen, never say never.

I have seen dedicated JASO certified motorcycle oils on the shelves of good quality MC dealers and parts/accessory shops. Some of those oils tend to be very expensive as well.

I just recently got rid of a nearly empty bottle of Yamalube 20/50 I used with my old FJR, and I'm quite certain it wore the Jaso MA mark. I'd bet the 3rd party suppliers filling the Big 4 MC brand oil bottles are putting JASO certified oil in those bottles, since the MC manufacturers tell us to use JASO oil in their engines.

The reason behind this is 40w and higher will NOT have friction modifiers. These were added for fuel economy in 30w and below and can/will cause clutch slippage in some wet clutches.

My mantra is if 40w and higher probably OK. I only use Mobil 1 Motorcycle Synthetics. If Yamaha fights a claim I will let them and Mobil 1 sort it out.

FYI, MA was superceded by MA 2 due to catalytic converters. If your bike has a CAT, I would use MA 2 oils.

I use Rotella exclusively in my Yanmar 4LHA-STP turbo diesel in a Shamrock offshore Tuna and Marlin hunting machine. It sucks up the normal diesel contaminants. Why the truckers swear by it.
Unless Rotella has broken out of their core market it is diesel oil supremo. And nothing else.
School me if I am wrong. I live to learn....

When I get a chance I will stop at a dealer. Problem is a new shiny bike may catch my eye.

I'm sure there are others who have mileages like that using certified oils. I'm not convinced having paid for the logo means a hill of beans in real-world application. Failures are not an option for these suppliers as word of mouth from users probably has more impact on sales than slick marketing.

Iím with you on that. Going by what others have done and having an oil analysis done to confirm oil longevity/breakdown to set my drain interval.

I am a synthetic believer. The unbiased test data is out there for all to read.

Until somebody proved we would not sail off the end of the earth, we all that it was flat.

Rotella's T6 15w40 is the talk of the town right now over at BITOG. Mostly due to the level of shearing you get with the 5w40 T6. If the 15w40 is more shear stable I'll consider it. I've seen the 5w40 shear to a 20 weight in some bikes.

Are we talking Blackstone or equivelent testing? I run the 5w40 T6 in everything I own from Tractors to generators. I run it to 10K in my DL but have not sent it out to test for 5-ish years. So did something change?

Correct, there are lots of UOAs (Use Oil Analysis) on BITOG that report the shearing, sometimes as high as 25%. Obviously not a major issue when you look at the experience of users that have gotten loads of miles on this oil. But it's worth mentioning in a wet sump bike. If it is meant to run on a 40 weight, I would prefer to have a 40 weight oil for the duration of the OCI.

I'm currently running Valvoline 20w50 conventional. Shifts like butter. I suspect after 1000 miles it'll shear to a 40 weight.
