Still looks good, even though this one has 1k less on it.

Still amazes me how highway driving keeps the oil in much better shape. Wife's current fill of mostly city at around 7k is not going to look near as good...

Zero oxidation? Is that a typo?

Your UOA's make me want to use Mobil 1 0W-30!

My Hyundai loves that oil
( or so she said )

I currrently have this oil in my Ranger.. since last fall. Can I use 0-30w year round?

Of course. I use M1 0-20 year round.

Why is that hard to believe? Steady state driving with a fully warmed up engine means the engine has almost no wear at all during that time. It's when the engine is cold and you're driving in the city (or driving it hard) that the oil takes all the beating.

Nope - that's what the report (Schaeffers) says...

Thanks for posting this. I am running this oil in my truck and my Avalon. I sure hope my results are this good. Congrats on a great report.

 

[ltslimjim]

That's an awesome report.

 

[oilmaven]

Nice report but no boron in this oil?

 

[Al]

Great report.

 

[Gokhan]

Thanks for this UOA. Looking great.

Your engine seems to like the slightly higher viscosity of 10W-30 better as far as wear is concerned. Perhaps sometime give the M1 0W-40 a UOA try for the fun of it.

If you see a out of line number you should immediately request a retest. They have the sample hanging around for a few days usually. If it was zero on the sheet of paper from Schaeffers they entered it wrong. Or something in their test equip. is broke. They obviously did not look at the report for a sanity check. Really need the TBN also.

I don't understand the comment concerning the wear differance you stated.

I don't see 10w30 in his report, I see two runs on M1 0w30. The OP just typed them slightly differently. "M10w30" in one column and "M1-0w30" in the other. 10w30 would look like "M110w30" or "M1-10w30"

Maybe the OP can clarify, but I'm guessing both UOAs are for M1 AFE 0w30.

 

[ltslimjim]

Ha, and ironically the 'better looking' UOA seems to have the weaker add-pack as far as the sample itself goes. I'm guessing both SN M1 0w-30. Looks good.

However, it is true having TBN included for the miles is probably a VERY good idea, and I also don't buy 0 oxidation.

 

[Gokhan]

I see. They are both M1 0W-30 and both SN.

Since the additive numbers are so grossly different between the two samples, there seems to be a lot of error in the measurements by the lab. You wouldn't see that much difference between two samples of the exactly the same oil. The same error argument would then also go for the wear metals. It looks like either the first one underestimated or the second one overestimated the concentrations by a large amount.

I would suggest switching to Blackstone or some other lab next time.
