Is there a current T6 0w40 CK-4 or was it discontinued when the new spec came out? I can't find a current PDS.

If yes, is it safe for modern diesel engines with DPF's?

Maybe Garak or someone from Canada can chime in.

I ask because Advance Auto has it on sale with free shipping just in time for winter:;gclsrc=aw.ds

The new bottles of RT6 0W-40 at my CT store aren't CK-4.

Don't think this oil is being upgraded for that spec.

If you happen to go somewhere that sells it can you take a picture of the back of the new jug for me? Thanks!

I'll have to take a peek when I'm at the store, too. I haven't looked all the closely. Either 0w-40 CJ-4 or a hypothetical CK-4 would be safe for a modern engine with DPF, assuming it's taking an ordinary HDEO. The SAPS will probably be the same, a good guess of around 1.0. Heck, that even applies to E6 lubes.
Plain, simple Garak.

Looks like you could at least use that in a Ford Power Stroke.

Never seen it on the shelf here in Michigan, usually just the 5w40 only. The only 0w40 I've seen is John Deere oil at $50 a gallon around me.
