Clarification on Rotella JASO-MA "Certification"

My understanding is JASO doesn't test... JALOS doesn't test... the register (you) did test and complied the technical performance data for review... so the mark is based on trust???

I've always been concerned with wet clutch protection and shearing of 0w or 5w oils but Rotella makes the claim about how in testing it stays in grade and resists sheering. So is the consensus that Rotella T6 5w40 full synthetic will protect fine in a wet clutch CVT application like ATV's?



I've been using T6 5w40 in my grizzly and 2 kodiaks for 8 plus years no issues.

BusyLittleShop...

You're right. JASO and JALOS do not test. The submitter is completely responsible for the quality and performance of the oil represented by the data. Most of the basic data was developed in my lab. Clutch testing was done by the additive supplier and a few were confirmed by an independent lab.

Thank you RDMgr... I'm saving all your info for my customers... can you name the additive supplier and the independent lab and anything else you wish to share???

I really can't disclose specifics. I'm under a nondisclosure agreement.

I just want to clarify something with all this stuff about Rotella T6 being JASO-MA "certified".

It's my understanding that it isn't JASO-MA certified. A JASO-MA "certified" oil has undergone the testing to be allowed to display the certificate on the bottle like what Motul has.

This is the JASO-MA certificate and I believe it's present on some 'motorcycle oils' such as Motul et al.:

Rotella T6 does not have this. They have the API certificate (round stamp on the right) but that's it as far as "certifications" go.

So I guess you could say that people wouldn't use it becuase it is not JASO-MA certified.
Fair enough, the manufacturer "claims" it meet JASO-MA, however this has not been certified. At the end of the day, the manufacturer can "claim" anything they want, right?

At the end of the day, it is a good oil and does seem suitable for motorcycles as plenty of oil analysis' have shown. All I'm trying to do here is to cut through the hype and get to the facts regarding oils that "meet a particular standard" as opposed to oils that "are certified and have undergone certification".

I'm not trying to dump on this product. It's a great product. But you don't just say "it's certified" becuase it isn't. Just like a guy in a white coat in a hospital isn't a "certified" doctor without the proper certificate even though he might have the knowledge to provide you with medical care.

Oh, and FYI I'm not drumming up business for motorcycle oils. Personally, I use Delo 400 15W/40 Multigrade in my 1050 Speed Triple and in my TTR250 dirtbike

I have/use Delo 15-40 in my TTR250 and it seems to work geat. No complaints.

Ran Delo 400 LE 15w40 in the ZRX 1200 about 5 years ago. Worked fine, had a LOT of Boron (356 ppm after a 3,200 mile OCI). Had a fuel dilution issue for whatever reason, as that is not typical of the bike, and flashpoint was 375 so viscosity was not accurate relative to the more recent oils I have been posting.
