Fuel filter Bosch or Wix
Start by replacing the ancient NAPA fuel filter, and only use a Bosch version.
I've always used the Wix fuel filter, and it worked well I guess. Lol.
I’m on my 2nd fuel filter this week, was getting a bit of black smoke out of the exhaust so dumped injector cleaner directly into the old one and revved the stones off it . Big clouds of black smoke! Then changed the fuel filter for a fresh Bosch one and exhaust is back to normal now.
Wix for fuel on the 7.3, but Ford OEM(Motorcraft FL-1995(A) ) on the oil filter. Never an issue.
I have 115,000km on my 2022 LM2 Silverado. So far it's been great, but some people have experienced serious issues on older ones. Gm is constantly improving this little motor. Lessons I've learned myself or through several forums and family members with the same motors:\n\n- Fuel additives seem to get better mpg and less regens \n- Only available oils are amsoil, mobil 1 and OEM. (Amsoil isn't dexos certified though)\n- Oil changes are pricey compared to gas, cheap compared to bigger diesels. I pay $250 CAD \n- Known to crack radiators (top right side) as well as water pump leaks. \n- Many people tend to replace the MAP sensor or clean it after a while to make it run smoother, it's a cheap part. \n- Doesn't seem to burn oil, but mine is consuming a little coolant lately (I suspect radiator).\n- The factory fuel filter is 5 micron but Wix makes a 2 micron replacement. Cheap and easy to do yourself. I pay around $50 CAD\n- Everyone online thinks they have blow by, they don't, just have a lot of crankcase pressure\n- Mine seems to misfire when started in weather colder than -15C for about a minute until warm. \n- A10 trans is smooth but has the odd rough downshift, I also follow the severe service interval table and change fluids with amsoil and new gm filter \n- Def consumption is never an issue other than towing. If towing anything heavy bring a jug or two. It will go into limp mode when you run out.
the inlet side of the filter being completely gunked with black varnish.
Wix is only $2 cheaper on rockauto. $28 vs $30.
Ive had this problem when people use crappy fuel filters too. Wix and fram and baldwin are awful.
not the wix. I had their filter for a few months. it started leaking and the seal wouldn't fit anymore.
