I only had the truck for 30,000 miles. It had a lot of highway miles At first according to carfax. It appears to have the original Cp3 pump I was just wondering how long it lasts. I sent an oil sample out to Blackstone labs and they said the engine is an excellent shapeOBO? You mean the Odometer button? I tried that, and it just lights up all the dash lights.
Edit, never mind, got it...you have to turn key on first, then hold ODO button for like 10 seconds.
I’ve got 5200 hours on 218K miles. Did yours idle a lot?
