Oil weight for 5.3? 0-20 no good?

[vcode]

The issue with the recalled 6.2L is traced back to supplier defects (crankshaft) and has no relationship to the oil viscosity. Millions of vehicles have been using 0W-20 since Circa 2010. I have used 0W-20 for 15 yrs in 4 GM trucks, never been any issue.

So have many fleet managers with many more trucks than you have.

4 vehicles in 15 years.. about 60K miles per vehicle ?

Fleet of 1/2 ton light-duty pick-ups ?

LOL, you know that the oil pumps are positive displacement right?

Positive displacement, meaning that for one revolution they pump the same volume of fluid regardless. Your graph above is only true for rotodynamic style pumps and totally not applicable to a forced oil lubrication system that uses a positive displacement pump.

There are fleets of 1/2 ton light duty trucks.

My company actually provides me with a fleet lease vehicle that happens to be a 2021 Silverado (with the 5.3). The lease company (its called "wheels" now, it used be named "Donlen" before Hertz filed for bankruptcy during the pandemic) pays for everything, even toll road fees.

For maintenance they just send me an email that I print out and take wherever (I normally use a Jiffy Lube that's close to my house). And the ole Jiffy Lube puts in whatever oil is recommended by the manufacturer.

Menards has a lot of them by me. Enterprise, Avis, and others have them as well.....

Gotcha. Rental cars, (duh… I rented a Silverado 1500 not too long ago for a business trip…) and “supervisor trucks” as we would call when we found a old commercial 1/2 ton in great shape at an auction, haha… basically trucks that live reasonably good lives compared to their HD counterparts.

Yeah pretty much,,, like its in the lease policy that I am not allowed to tow anything, at all, ever, for any reason, with my fleet lease 1/2 ton truck. So it lives an easy life.

Those people that have need for actual real trucks get Dodge 4500s with utility beds.

I see atrocious mall crawlers in Dallas suburbs ALL the time so my perspective is skewed that anything above a custom or LT trim is likely used that way … really serious 1 ton dually trucks with rubber band for tires used basically as a car :/

Chevy has a whole line of 1500 W/T work trucks. I never see them at the dealer as they are usually special ordered and in the back lot waiting for a commercial customer. The county/city/village here use 1500's as well. We have mall crawlers here in WI, but it's not an epidemic! There was a guy here with an S-10 Blazer on 44's (lifted suspension and body) and I actually saw him flip it in the snow. It was absolutely useless.....
