Did my first oil change last night! Who put that filter on? I could do chinups on the filter wrench without turning the filter. Got it off, its black with a part #897214983 not #88917036 or PF-2232 that the owners manual specifies. Curious??? I used a PF-2232 for now and Rotella non Synthetic. I like to break an engine in on Dino and switch to synthetic later. Very interesting looking around under the truck, exhaust and such and whats the deal with the return fuel line going thru a cooler before dumping into the fuel tank ?? Also plugged the plug that was half out on the tail of the tranny.
