T6 MULTI-VEHICLE 5w-30 IS NOW THE ONLY ROTELLA THAT WILL CARRY AN API GASOLINE SERVICE CATEGORY MOVING FORWARD.

Taken from another thread on this forum. What happens now when someone new comes here asking which oil they should run? What will current Rotella users do?

Lets wait for some VOAs or other solid information on what the additive packages actually ARE.

Many people running Rotella in gas engines are doing so in an engine that doesn't need an SM or SN rating- that's one of the whole points of even using Rotella in a gas engine. If you're using it "off-label," then what do you care what rating it carries? For vintage big-block or other flat-tappet / big valve-spring engines, the "diesel-only" T6 5w40 should be fine (pending looking at a VOA to see if there's any benefit). For newer engines, the 5w30 that still carries the gas engine rating should be fine.

The current T6 5W-40 data sheet on Shell's website still has SL and SM listed.

Bingo - If I decide to run off-label it's my decision. If the VOA/UOA's come back similar to old, who cares what the label says.

How many times do we break the speed limit? More times in a day than I have fingers and toes. But usually not for prolonged periods. Plus, everyone around me is running 5%~15% over. What am I supposed to do, slow everyone down ... laugh

But they've already announced that from now on it will NOT carry gasoline approvals. That's not in question, the SM/SN rating will be going away on the 5w40 grade. Starting with CK diesel oils, there will be a clear distinction between "high Zn/P" C-only rated oils for diesel engines (and other "off-label" applications where you know what you're doing, such as old flat-tappet V8s) and "Low Zn/P" C- / S-rated oils for modern-era passenger cars and diesels that allow them also. Rotella appears to be tying that distinction to the T6 5w40 being the C-only product, and the new T6 5w30 being the C/S product.

Hi, Dave.

This is the data sheet you're looking at, correct?
http://rotella.shell.com/products/t6-ful...t6-brochure.pdf

This is for the old CJ-4 product, not the new CK-4 offering.

So the question on my mind is..

.. Once these CK-4 jugs come out, without the API S(L/M/N) certification on them, the oil should still technically be safe for use in a gasoline engine that does not burn oil, correct?

This thread and the other one on the same subject should get "merged" IMHO.

^^^ +1

That's all you need to know for motorcycles smile

There are a few diesel bikes out there. But 99.9% are gas, and JASO is about gas engines (and clutches and tranny's, etc.).

The rating I am concerned with is the JASO MA rating, which is the motorcycle rating for Japanese bikes. But, after seeing how low the oil rated, I may switch.
