Mobil 1 ESP 0W-30, 3.8k miles, 2022 Toyota Tundra

[Jordan_FX4]

Hi all, attached is the latest UOA from my 22 Tundra with the 3.4 I-Force engine. This was the second run of M1 ESP 0W-30 on the replacement engine. 39,940 miles on the truck, but 7,549 total miles on the engine at this change.

I noticed the calcium level was totally different on this run. I’m not sure if this is because of dilution from the FF, or because of a reformulation. The last run was from the new style M1 jugs and this was 5qts of the old style jugs + 2.5 quarts new style M1 jugs.

Anyways all comments/thoughts welcome!

Can't open link to see your UOA?

Sorry, hopefully it's good now. I was reformatting the image to make it more reader friendly.

Seems every SpeedDiagnostix UOA/VOA has at least one strange result. Ask for a rerun.

Agree with @Glenda W., ask them to retest. That Calcium is high. Si is coming down nicely! Overall results looks like this oil is working well for your replaced Tundra engine.

Yeah, there is no way Ca is that high.

Almost looks like the SN version of m1 0w40 FS

I don't think I've ever seen Calcium in the 4000s! It kind of makes it hard to trust any of the other numbers on there!
