Hi All
This is my first UOA from my 2021 GMC Sierra 2500 HD 6.6 gas L8T truck has 32,000 miles. Had the truck since new, been running PUP 5W-30 with an ACDelco PF63w/filter mag since about 6,000 miles on the clock. Unfortunately this truck uses about 1 quart every 1,500-2000 miles been doing it since new it’s a common problem with some of these L8T engines it seems. I guess this seems like a good report? Curious as to why the viscosity is so low though.
Never had one of these analysis done before tell me what you think. Black stone did mess up the UOA report and states this was a duramax when I clearly filled it out for GAS truck. I’ve contacted them to correct the report, hoping what I have here is actually correct for my truck
-Tell me your thoughts!!!
