Good TBN at 10.94, but Im not sure about the add pack. What do you guys think? I know a lot of guys that run Rotella in their jeeps and motorcycles and they swear by it.

Looks in the same ballpark to me from a VOA done back in 2011 by Blackstone Labs.

Much higher NOACK than what I expect from a synthetic.

What's wrong with the add pack? It looks pretty typical for an ACEA E7/E9 lube.

I agree Garak. If people don't see a 200+ for moly or boron, they downplay the product. Tough crowd.

Does T6 still have sneering issues?

Should be good for an old flat tappet hot rod - but so is M1 0W-40 & 15W-50. As well as the cheaper QS Defy.

This is my thought. So many people are stuck on the diesel oil for the Jeep 4.0 because of the high zinc. Every time I mention Defy and its zinc content (and post links to PQIA) folks just go ehhh. Too many people still think SOPUS products cause sludge too. I am done trying to convince otherwise. Keep the demand low so its cheaper for me.

Balanced add pack. Higher noack than I expected. I guess you'll have that when you have such a spread in viscosity.

M1 0w-40 has a higher spread and much lower NOACK (8.8%).....

Great oil for motor cycles with wet clutch. It's JASO certified. I don't think you can get a better bike oil (dino or synth) for the price.

Defy zinc is <1000

Many of us have seen engines with stuck rings and severe sludge from SOPUS products back in the day (70's and 80's). In fact, the 10W40 was so awful in the 80's that GM even put out advisory that warranty void if 10W40 used. That long memory persists. I have cleaned many a piston with stuck rings from Sopus oils. That said, I use Defy, and it does better in my car than M1 or M1EP. Times have changed.

I still can not stand to use a Fram filter, again, from back in the 90's after they closed the Nevada plant and filters fell apart. Maybe someday.

Of course, neither Quaker State nor Pennzoil, both criticized for their performance in those years, were part of SOPUS at the time.

Personally, I'd blame the 10w-40 over the brand at the time.

"Does T6 still have sneering issues?"

Always...Just use Delo 15w30 instead.

 

[FutureDoc]

Just mix some T5 and Defy and it becomes unicorn tears...

Just to clarify, the GM advisory was not specific to SOPUS products, but rather they banned all 10W-40s due to ring sticking.

It was also believed at the time that there was more to the ban than just technical issues - certainly not all 10W-40s caused ring sticking. The industry was trying to get 5w30s readily available to the public, which was a requirement for using this fuel efficient grade in CAFE testing. Retail stores were reluctant to give valuable shelf space to 5w30s since there was so little demand, in spite of new car manuals requiring them (new car manuals only influence new car owners). The largest selling grade by far back then was 10W-40, so by attacking the 10W-40 grade it was expected that the shelf space would move to 5w30. Not long after, the EPA allowed 5w30s for use in CAFE ratings.

Doesn't Tom's post sound familure to today's distrust of xw20 by many a bitoger? How things change. How things stay the same.
