Adam….100% spot on! I’ve spoke with friends and some dealership owners/techs That have eliminated the a AFM/DFM and switch to 5W-30 and I’ve had no issues.
I know leasing is not an option for everyone…… but in my opinion these trucks I’m not worth sub 60/80grand and probably won’t make it to 100,000 without some major repairs. So leasing is a good option to give them back their POS. It works for us and I have a good rapport with my dealership so going over miles is not an issue either I sell them all right to a private party or the dealership buys them and covers my down payment. Been doing it for years. Except I bought the 06 Chevy crew cab which my son now still drives
