2007 GM 6.2L w/186k, HPL PD 0w20 w/3400

In Dec 2022 I sent a virgin or baseline sample of this oil to OAI. See the "BL" sample.
Recently I sent a uoa sample of this oil to OAI to do a "value" analysis. See result #7.
Oil has 3400 miles, 67 hrs mostly hwy, avg 50+ mph.
The vehicle is a 2007 186k mile Yukon Denali 6.2L all aluminum L92.

Sample#BL = HPL PD 0w20 - 3400 miles
Sample#1 = M Delvac ESP 5w40 - 8100 miles
Sample#2 = M Delvac ESP 5w30 - 6200 miles
Sample#3 = M Delvac ESP 5w30 - 8600 miles
Sample#4 = Kirkland 5w30 - 10,200 miles
Sample#5 = Amsoil ASM 0w20 - 6235 miles
Sample#6 = same load as #5 above - 8300 miles
Sample#7 - HLP PD 0w20 - 3400 miles

What say you?

 

[The Critic]

This is a modified version of their "race oil" that has little relation to their main lines, correct?

 

[fantastic]

Some wild variations on the iron. What are you thinking may have caused the spike?

This IS about the 0w20 "motor oil" that HPL Superior Lubricants of Hebron, IN sales & distributes, 219-996-3460, it's not their "race oil".
This is NOT about any oil that HPL Advanced Lubrication, LLC of Manteno, IL sales & distributes.

To add to what I said previously "the vehicle has been averaging 18.4+ mpg on this load of oil. It consumes about 1/2 qt per 5000 miles.

Awesome MPGs.

Man, I can't get used to the layout they use in their analysis. Iron levels don't look great even for LS standards. I'd go back to the 5w40 Delvac. It's goodwill lasted into that 5w30 change.

Seems the Amsoil 0w20 performs best in your engine.

All aluminum block? Those iron readings say otherwise.

All aluminum block? Those iron readings say otherwise.

Commonly a bore on an aluminum engine has iron sleeve's.

I get 18mpg in my 2009 5.3l 6l80 burb. That's good mileage with your awd and 6.2l.

I would go 30wt. I'll try 0w40 one of these days.
