@donjetman How long did you run that mix of VPB and oil for? Your results are pretty convincing.

@Dustin Jackson
5100 miles, took a sample and sent it to the lab. Changed the oil with the same, put 1000 miles on the oil and then did this mx. Saved it and put it right back in and will run it till it has 5000 miles then send in a sample and see what is what.

Its not Valvoline Premium Blue, It is Valvoline Premium Blue "Restore", completely different and off the market for yrs now. I got lucky and found someone with 4 gals they didn't need and bought it from them.

I'm mistaken. I stopped by the local Cummins dealer in San Antonio, TX and they had 10 gals of it, $80/gal

you never know when your gonna need some, and you never know when they'll stop selling it, so I bought some, its quite unique.

In my stock 2007 Yukon Denali L92 no afm with 272,000 miles, I use Banks Automind to raise idle to 600 or 650 rpm. This raises idle oil psi from about 14 psi to 18+ hot. Makes me feel better.
Cold start oil psi is always 50+ at 55 degF and it is 35-40 psi from 1200-1500 rpm hot.
I use costco or walMart Synthetic 5W-30 and ACDelco UPF63R (vette?) Filters with oil changes about 7 to 9,000 mile's (10 to 20% oil life left per dic).
Bigger area and higher bypass pressure in UPF63R, is it helping or hurting in my quest to get to 350k miles?
I run it hard at elevation in UT, NV, and Co, off road a bunch, and carry lots of stuff, 2960 front and 3350 rear axle weights BEFORE I put the 340 lb. Moto and rack 2 feet back of the hitch.

my only 2 cents on your quest for 350k is that's a long change interval. that 5w30 if driven hard is probably lost a lot of viscosity by then.

when driven hard, I'd personally go with a 10w30 or 40, more room to thin out over use and heat. then change about 5k miles.
