Two samples from my Tahoe. In my infinite wisdom I forgot to write down what oil did I use for the latest OCI. I only use PP, Castrol Ti or Edge, and QSUD. This is not Castrol, as there's no Ti. Most likely QSUD, but the additives don't match the previous sample. Oh well... Maybe someone has better idea by looking at the ad pack.

In both cases the OLM was at 23%. The latest run involved 4,000km trip in a week, right before the oil change.

Both oils were boosted my LiquiMoly MoS2, about half a bottle.

Cu, as usual, is most likely from the oil cooler. AFM is tuned out, the engine does not use any measurable amount of oil in OCI. I also have double-stage catch can, in addition to improved latest and greatest driver-side valve cover.

I need to talk to WearCheck about the meaning of the numbers at the bottom, they look confusing to me.

QSUD doesnt have that much moly smile

What oil filter used? That's helpful.

How is your report compared to non treated Shell synthetics or the Castrol Magnatec darling of the year.

I'm running 10w30 QSUD. Good stuff but too thick for my Nissan 2.5L

I fixed it though smile

Guys, please ignore Moly. As I said before, the oil has LM MoS2 additive in it!

The filter in both samples is Fram Ultra.

The current sample has essentially no Boron. So that probably isn't QSUD.

The earlier sample is tagged as QSUD but it's not that either. Calcium very low and magnesium very high. That looks more like a M1 5w-30. It certainly isn't PP or Castrol Edge either. It it were an old version of Castrol (pre-2016) then that would explain the Magnesium and low Calcium.

Thanks GTX, you're right. Gee, I really need to get on top of what I'm doing there. The first sample could definitely have been M1 5w30 EP. I remember having two jugs... As for the second one- beats me. I only shop at Canadian Tire for oil and get what's on sale. There's pretty much no other choice between the brands mentioned....

How long have you been using the LiquiMoly MoS2?

For the last four OCIs. Two years or so. Got it at wholesale cost, thinking why not. Also using it in wife's Mazdz CX-5.
