Since the "old" Rotella T was phased out in 2017, I have been using the new Rotella T4 that replaced it in my 2016 300xc. I noticed no performance issue or difference, until a ride last weekend, when I started experiencing high rpm clutch slippage. Disassembly of the clutch and inspection and measurement of the wear pieces (exp disk, steel plates, fiber plates, etc) showed everything well within wear specs-so I was quite perplexed. In talking with the Rekluse tech support line today they mentioned they've "heard" riders using the new formula line are experiencing similar issues to mine, and are no longer recommend Rotella oil. I looked into this and according to the Shell website, Rotella T4 is now JASO MA01 AND MA02 certified, and furthur reading shows the MA02 qualifies as having less friction. KTM owners manual specifies oil at the MA01 standard. I can't seem to find any specs for the "old" Rotella T line to corroborate if it was MA01 only (and not MA02.)

    Can anyone confirm the "old" Rotella T specs.

    Is anyone experiencing similar slipping issues?

    In the interim, I am now actively looking for cheap gearbox oil.

    I happened to be in Wal-Mart today and thought i would check the JASO-MA rating of the T4 and T5 and they are not rated as a JASO-MA oil.

    Is the rating just something Rotella decided not to pay for? Many times these certifications actually cost money to have. BS like "Certified Organic" just being a tag you can pay for to advertise

    Yes, it costs to have the rating on the bottle it`s around 100k. For Shell this is chump change, who it hurts is the small company who can pass the test but really cannot afford to pay the 100k for the rating.

    The question is was Rotella ever a JASO-MA rated oil? I brought this up a decade ago, a friend now retired was an engineer at Shell and had no knowledge of this JASO-MA rating and said that most likely it was marketing. I was also told that because of all of the pressure from the FED`s to make it a clean diesel oil with the new diesel engines the least of their worries was a JASO-MA cert.

    From 2005 to present there has been nine changes to the Rotella formula in order to meet Federal regulations and to sell at a cheap price, also pre 2005 it was rated a HD oil and lost that rating after 2005. Back then i warned of the changes and the changes to come, not one person that i know that was using Rotella back then is using it now as most have learned hard lessons even the aftermarket clutch companies after conversations and actual testing have seen the light.

    A new bike today is 10k or more, i cannot wrap around my head that after paying that much coin some go on a search for the cheapest oil for their investment. Any oil is the cheapest item one can buy.

    It costs to have the official certification. But what a lot of companies are doing is self-certifying it. Scamsoil started that years ago, and many other oils have picked up on it. You need to look for things like "JASO certified" as opposed to something like "meets JASO specs". The JASO certified ones will usually have the JASO symbol as well. You kind of just need to trust that an un-certified oil "meets" the specs if they claim it does. I'd guess most of them that list it actually do meet the spec, but it would take money to prove them wrong, so I doubt it's checked very often. This is not just a Rotella or Scamsoil thing. Lots of name brand oils with motorcycles on the labels do the same thing.

    Rotella T6 still lists the JASO rating (self certified apparently), and the old T3 did also. But it seems the newer T4 and T5 can no longer meet those specs.

    The T4 I purchased at Walmart in September still shows it. As does the older jug in the cabinet here (early summer).

    I don't know man...things are gonna get sketchy pretty soon...as of yesterday this is all a I have left. HAHA

    There's 2 more oil changes left in the jug to the left also.

    Like I mentioned before when this runs out I'll go to Honda GN-4 oil. Friend has been using it for years and swears by it.

    Just looked, and I found the same thing. I've got bottles from a case we bought early this year and a case we bought a week ago (we own 4 diesel motors). All say JASO MA.

    For kicks, I looked at my jug, bought late last year, has the JASO MA.

    I like frequent oil changes, I like the cost of rotella.

    That`s concerning. I guess in some areas old jugs are being used? I checked again today at Wal-Mart and none had the JASO MA cert.
