@Grumpy Bear the conclusion from your post about doubling engine life has me curious. Are we literally talking an expected life of 250,000 miles potentially becomes 500,000 miles with a step up in filtration for fresh oil at "the oil factory" when it's bottled? I know you said that's a single variable among many, but, that's significant if the implication extends that far into a real world use case. I would think the oil marketing folks would really eat that up and make it known. Particles introduced during oil change is a fairly easy one to avoid, but probably not intuitive as one would think. I.e. using a clean funnel. But...what was it wiped with? Paper towel leaves behind little fibers. A solvent if not dried is not something one would want to introduce into their engine with clean oil. And, keeping the oil filler neck clean and free of buildup.. Look at some guys engine bays and they're an absolute mess. Some say that's better than the drawbacks of cleaning it. I'm not a buyer of that idea. I've also wondered if "flooding" the top end of the engine with oil while filling is a bad idea. During normal lubrication the oil flows in a gutter back into the galleys. But if you flood the area you're potentially washing the top of the rockers, springs, and other areas which may not get much oil wash normally, and you're mixing all that into the new oil. I just don't have the patience to pour slowly. 😆 -

It was a bad pump, i had a dealer next day the pump. Gm part #86591535. Tools needed 10mm socket, pliers for hose clamps, 1/2gal of Dexcool. About 30mins to remove and install, pump located near oil filter on driver's side frame rail. I had a local mobile mechanic delete the code, he had a snap on scan tool. My scanner could not delete the code. I drove back home about 700 miles since then, and no check engine light. Hope this helps someone in the future in the same situation i was in. Thank you to all that helped me. -

Hi Gary, I guess it all boils down to personal preference and what you can afford. I, personally, buy new because I will know from day one how the vehicle is maintained and driven. -
I think the 2027 trucks look great, although I will be keeping my 2025 since it will paid off in January. Now, in the original post it was stated that the 2.7 finally gets the 10 speed. I'm not sure that's a good thing. So far it seems like the revised 8 speed from 2024 and on is a better transmission than the 10 speed. I guess time will tell.
