It's both funny and sad to me that GM's most reliable truck engine right now is a little cracked out turbo 4.

If its THAT sensitive to oil type and viscosity, they need to go back to the drawing board.

The problem is GM uses cheaper & cheaper internal parts because the share holders are more important and dividend payments to them matter way more than quality products

Oil type is not the only problem on the L87. It was built with a lot of Chinese parts

But 0W-40 is only at higher temp. It would be better with a 5W-20😭

So what your saying is GM doesn’t want to fix the actual problems they just want to try different maintenance methods and hopefully the engine lasts until the warranty has run out.

Unfortunately, this is gonna be a more common occurrence with companies trying to meet emission regs by using thinner oil.

It would also be nice to not spend over $100 on oil for every oil change

They haven’t recalled the 2019 engines yet. Mine has been sitting with a blown engine waiting. Blew in 2023.
