Old/ new Rotella syn?

[OAS]

Question on the Rotella T synthetic.

Just changed oil in my 2.9 Bronco2 with the newer CJ4 blue jug 5-40.
(it taps much less on startup with this in cold weather)

I have a quart of the old CI4+ RTS 5-40 that i kept as a spare/ top off from last year.

Are there any ill effects to add this CI4+ to the CJ4 as a top off?
Will the additive packages combine and cause thermonuclear meltdown?

LOL!

Just call before you do it, so I can get to my shelter

I have done so, in ATV's, and the blast was negligible. I noticed no problems, but did not do a UOA.

No.

No compatibility whatsoever. CI4+ just has higher additive content. Both are excellent grp III base oils.

I think you meant to say incompatibility

....we don't want to confuse the guy.

Yep--I gagged. Incompatitiblity is the right word. RTS is for sure one of my favorite flavors.

Does anyone know when quart bottles of the new CJ-4/SM RTS will be available? I've seen quarts at Walmart but only the older CI-4 formulation like what the OP has.

My car takes 5 quarts and it would be nice to find matching little buddies for my gallon containers, lol.

Both of my local WalMart stores now have the quarts.

Great, thanks for the info Frank. Hopefully my local Walmart follows suit soon.
