Stan, this thread is specifically related to the Duramax 3.0, in the 2019-2026 powertrain subforum. If you'd like to talk about your other vehicles and offer anecdotal stories about them, please consider starting a thread in forum that pertains to your truck, or the other vehicles/ Off-Topic section if they are not a GM truck.

On a separate note... anyone had the experience while filling up and another customer finds the fake "scam screw" on their pump and they freak out, screaming at the attendant? Pure BS. Still too many many gullible people out there. The guy today made me want to hose him with gasoline and set him on fire.

OE replica wheels are always a great option, and they are the same factory designs from 2019-newer trucks. Search results – OE Wheels You can do plenty of the newer style 18" wheel options in different finishes. Good quality too, I've ran this brand before.

I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt. I would love to do what he is doing and would do it if and when I hit the Powerball. I'm not a Tribologist by any means but love to learn what I can. I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this. The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out. Most don't bother, they just want to believe what they first see. I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20. Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try. Still the same viscosity at 100℃. In the end we all just do what makes us happy, life is too short to get upset over trivial social media. On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore. "Like a Rock" has been long gone. Seems "Built Ford Tough" has as well.

Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire. IMO

One word. Ugly
