M1 0W-20 11,000 OCI 15 Corolla 2ZR-FE 51,000 Mi

Hi folks, Was pretty skeptical of the 10K factory OCI recommendation when my father bought this Corolla. Did this analysis to actually see how it was doing. Looks like I have nothing to worry about.

Looks great! Doesn't get much better than that. Very boring report which is a good thing. I'd prob keep it to 10k since that's what the manufacturer recommends.

Looks great

Nice report, but with the calcium (way too high) and magnesium (way too low) levels this oil is almost surely not Mobil1 0w-20.

Agreed... But still a great report, OP.

I checked my TGMO UOA 0w20 and the calcium was 2115, magnesium 19, moly 28. So that prob isn't it either. Hmmm.....

 

[nicklx]

You guys are probably right. I could have sworn it was Mobil 1, but it seems I was mistaken. It has been awhile since I did this. For my next one I made sure to write down what I used and put it in the oil sample bottle. Thanks guys!

What oil are you running for the current fill?

 

[Artem]

That's a pretty clean running engine. Good results for whatever oil that is. Haha.

It's probably SuperTech oil from walmart!

Curious minds want to know! Are you a 100% certain or could it Pennzoil, Quaker State, Valvoline or something else? Any of those ring a bell?

Superb internal engine conditions, with a good oil.

 

[nicklx]

Still 80 % certain it was Mobil 1. Not sure which color bottle though. I just changed it and dumped PP High Mileage 0W-20 in. Ill do a UOA when 10K is up in a few months Then I will be exactly sure.

Could it be that has very little Mg ?

The older formula for Mobil 1 0w20 AFE had all calcium and no magnesium. This was from a few years ago. http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2142898

That's my thought exactly. It is Mobil 0W-20, but probably not M1. Either way, if this was MSS, that would be the goto for this engine. Hard to see anything doing any better.

It has Titanium. Castrol Edge 0w20 is known to use low-ish amounts of Ti.

6 ppm isn't an additive, it's a residue.

A few years ago, they used more, around 40 ppm I think. It appears they now use around 6 to 10 ppm Ti now, enough to keep their marketing claims of "with Ti" intact. Up to around 100 ppm is known to be effective. There is a tiny benefit to 6-10 ppm we might assume. For comparison, the new Shell Multi-Vehicle 5w30 has about 3 ppm of moly. That doesn't seem like enough to do squat.

Yes, that XM grp 3 synthetic.
