The only time I will go thinner than 10w-30 for a Jeep 2.5 or 4.0 is with Castrol 0w-30. I am a German after all.

I also noticed this.
There is no API donut on the label, only a statement that the oil meets API SL.
I therefore think that this is not an API certified oil, just like the old QS HM.
This could prove to be a very good oil in certain applications.
We'll have to wait and see what those who use it have to report, as well as the inevitable UOAs.
This could end up being a better HM oil than Maxlife SB, which carries API SM certification, in the right application.
I would trust SOPUS not to offer anything actually harmful to any car speced for an SL or earlier standard.

I checked my closest Walmart this morning. They have the 5-quart jug of 5W-30, but the 10W-30 and other grades were still the similarly-packaged "Enhanced Durability," which don't say synthetic blend, for the same $14.97 as the Defy. I'm not due to change oil again until June or July. I can wait a while to see if the Defy shows up, but I don't want to miss a good price.

The MaxLife (not sure if it was syn blend) was almost 18.00.

I got a jug of Defy yesterday, it looks to be a direct replacement for the older QSHM, it was mixed in with it on the shelf, the price was the same, and the receipt still said QSHM on it.

The word is already out on this oil I think, there was only 1 jug of 10w30 and a couple 5w30, the rest was the older QSHM.

No, M1 0W-40 is not a good choice for a 30wt application and it will be heavier on start-up to a 5W-30 at all temp's the OP will likely see.
Use a quality 5W-30; you'll be hard pressed to improve upon it.


Many Jeep 4.0s have shown good UOA results on Xw40 oils. Check the UOA forum. I think M1 0w40 is an excellent choice.

I do agree that a 5w30 in most situations would be thinner at startup than a 0w40. The mistake that many are making here interpreting oils is that the winter ratings are consistent across viscosity grades...they are not.

Bingo, Ill be doing a UOA with the M1 0w-40 to see
I haven't seen any 4.0 jeep UOAs with M1 0w-40 yet but so far they dont like Mobil 1 much since they are known to shed iron and m1 likes to give high iron uoas so we will see if the unique blend m1 0w-40 has what it takes to make a good uoa

Yeah, Mobil and the 4.0 don't mix very well.

A guy on another forum did a rather in depth study I thought, researching UOA's with 4.0's using a 30 vs 40 weight. His conclusion: The xw30 weights turned in as good, in fact microscopically better, UOA's in the 4.0 than the xw40's did. But clearly the 4.0 will thrive on either one, the numbers were so close. If your 4.0 is up there in miles or getting tired, the xw40 would be the way to go, otherwise I'd run a xw30 for better cold starting, and a little better power and gas mileage, at least in theory anyway.

He also noted the same thing, Mobil consistently produced higher iron numbers in the 4.0 than any other oil.

Except without tear-downs, that sort of extrapolation regarding UOA's really isn't useful. Each lubricant will have its own "signature" and it is variations or significant changes in the trends of that signature that one watches to identify potential problems.

I would say that your comments apply to Mobil1 and not other Mobil products. Just to be clear, since you said Mobil and not Mobil1.

The older M1 tended to produce higher iron in pretty much every application, not just Jeeps. However, the newer, SN M1 is doing much better. And M1 0w40 is a different animal altogether.

Yes, referring to Mobil 1. My main point was regarding the xw30 vs xw40 debate in the 4.0.

It is interesting, I book marked it.

Just did an oil change on my wifes 2000 Impala 3800, 177,000 miles with some Defy. Should be interesting to see what happens. I hope to do a sample later this summer.
