Shell Rotella T6: VOA for CJ4 vs. CK4

This shows some interesting differences.

So, as to the question about it now having moly and not being able to use it with a wet clutch. That is is probably correct right?

I know LOTS of people that use this stuff in motorcycles including myself.

The new CK-4 RT6 has almost no moly. The CJ4 RT6 had quite a bit. The new stuff should probably be fine in wet clutch bikes, imo. I'd be more concerned about the new RT6 lacking a SM rating.

Apparently I got confused by the side by side comparison.

It's unfortunate they pulled all of the moly out. T6 was my go to for almost everything. The moly content in the old CJ never had issues with wet clutches. Sportbike guys used it with great success for years and years.

Looks like I need to buy up the old stock locally. The moly oil additives are rather expensive.
