Pretty much.
Or skip GM, Ford, Chrysler and buy a Toyota, or Mazda that doesn’t wear out instead
This won’t work. By the time you get all those miles on the 6.2 engine then there is a good chance it is already blown up.
Like the Escalade that only made it 4 miles from the dealer.
These new engines have to be ditched. And return to the old and proven engines.
From what I am seeing it is not just limited to GM. Even Toyota engines are blowing up. Haundi, Kia too.
First of all, 5w20 oil, the first number means the base oil is a 5 (weight) viscosity. The second number is the viscosity when heated to 180 degrees. I pulled a tanker for 40 years and many loads of base oil into plants that canned it. They had 1000 tanks they blended additives into the oil. One additive they used was a really fine rubber powder. When the rubber heats up ,it expands and makes the viscosity go up. They also added other chemicals that aided the oil to adhere to hot metal. We had a couple of drivers that collect 4 or 5 gallons of the base oil and put it into their cars, within 500 miles their engines seized up. No high temp additives caused “dry” bearings.
The "myth" is not due to the company's wishes; it's due to government fuel economy requirements. Higher viscosity oil is generally allways better for wear resistance than the lighter oils. It slightly worsens fuel economy, though.
The 0 base number is supposed to be for starting at -30 degrees. If you don’t have temps like that then a 5 or a 10 or maybe a 29 base number should work fine.
Mebe GM should wake up and realize Active Fuel Management/Cylinder Deactivation crushes the engine.
The video covers much that is not in the text. The video was quite good.
The EPA has caused more engine problems for new vehiles. The whole (A) stop start engine when stopped is insane and saves nothing and causes engine issues. Even my 2011 Harley would shut one cylinder down was part of the EPA CAFE crap and for Harley that started in 2007. I immediately bypassed that BS.
The wife’s 2024 Volvo has that crap but you can’t shut it off. Asinine. Shutting down any cylinder while driving is just dumb and ethanol has done more harm than good to many engines.
Electronic technology and infotainment systems has destroyed driving.
I will never own a vehicle with that stop start crap ...
how long have you been an ams oil affiliate? Does it pay well when people buy through your links?
so switching from 5w20 to 10w40 won’t cause any problems?
My Ram calls for 5W20, but as everyone else has mentioned it was only for CAFE standards. I use 5W30 Pennzoil Ultra Platinum with a moly additive, but would prefer Redline 5w30. Only problem with the Redline is the cost. Great oil, but expensive.
Also, get yourself an oil catch can to stop all that bypass gunk going back into your engine through the PCV line. Empty every 2-3K miles and your engine will thank you.
Toyota is grenading engines too
The main problem is poorly made crankshafts that are eating the bearings.
That software “product hack” function for de-Washington-mandating car and truck engines sounds wonderful!
(Meaning the Obama-Biden-Harris FBI counterterrorism/counterintelligence agenciescwould immediately use it to track and infiltrate Red State car mechanics!
Change oil every 5-7.5k miles and don't buy a brand that build crap engines. I remember the VW oil sludge issues 20 years ago, it was a problem engine that VW should have been forced to recall every damn one of them. They didn't, but if you could show oil change records they gave you a new engine, I know. BUT, it was a CRAP engine and they knew it but didn't get much publicity.

Should you add zinc to engine oil?
Why Zinc Additives Are Important for Engine Protection. Zinc plays a vital role in protecting your engine, particularly in areas where high pressure and temperature lead to metal-on-metal contact. It acts like tiny ball bearings, allowing metal parts to slip over each other.
That’s what I do. It might be a bit harder to start when the temperatures are near -40, but I don’t live in Northern Minnesota anymore.
Same with my 2008 Nissan Frontier. It’s low mileage though, only 146k. Nothing but maintenance so far.
