Results from Dad's truck finally came in! How's it look?

Which flavor HPL 0w40 did you use?

Looks good. Unfortunately, there is no oxidation value so you can't see if it thickened to offset the fuel dilution which usually drops the viscosity regardless of how shear stable it is. This is why I won't use B/S Labs anymore. If B/S Labs is showing 2.0% fuel it is likely much higher than that.

The crazy high TBN of HPL likely comes from all the Mg they use. They're using about double of what Amsoil SS uses.

So 2.0% BS estimated fuel dilution is like, what, 10% in the real world?

Whatever the dilution, the viscosity held up. Good oil. I would be pleased with those results.

I would not be worried about the Al count yet. There can be "particle streaks" that occasionally cause a small, short spike in the softer metals. The other wear metals are fine.

Passenger car premium plus

Looking at the VOA database from various HPL formulas, they have anywhere from 1 to 3 to 18(!) ppm aluminum in the fresh oil. So I would not worry about the aluminum, but if you are you could send a VOA of your exact batch along with the used oil to Blackstone to see how much aluminum is in the oil itself vs wear.

Good UOA even with the fuel dilution. Hard to tell if the oil was thickening but the additives still look good with the TBN. I'd stick with the 10k changes and not go further. 10k because its HPL, otherwise I'd go less

I won't get a UOA anymore unless I'm getting an oxidation reading and accurate fuel number. Otherwise, you really don't know the full picture.

I'd say 10k on this oil would work well. Virgin test would give a better idea on Al but it would be wise as @buster mentioned to get fuel readings at the minimum from a different lab. Blackstone is great for their averages and other general test results though.

I would want to see an oxidation value before arriving at that conclusion.

Wow, 2% fuel dilution and still right there in the middle of viscosity!

I would run that all day long.....that is some killer stuff.

If it was me, I might test another OCI at 5k, just to see fuel dilution at that mileage, to see correlation in wear.

Good report. I'd say you're good for 12.5k miles.
