I should also say that I bought the truck with iirc 165ish k. With unknown history
That is what I think is happening but why? I feel like ive seen some idk what sludge? Come out when during oil changes. Makes me think that a lil crud is not letting a lifter or two seal.
As to what was used for oil. Don't think less of me but most of all the previous OC were just a speedy lube
I do all other maintenance. So this spring the trans went and I had just redone the fuel system about a month earlier tank, lines ,fill neck,sending unit,rear brake line. And few months before that I did all new brakes cut out some rust new patch panels some paint clear coat
Gold doesn't quite match o well. So after getting a new trans in when we started it was the first time it "ticked" it was due for an oil change so I went to speedy lube. So the 500 oci was speedy lube 5w30 conventional. The 1000 mile was castrol edge 5/30hm with a fram ultra . The 4100 started with castrol edge 10/30hm accidentally grabbed it not a big deal and the wix xp. But I did drain a quart like I mentioned and added 5/30 edge or miles sb 5/30. I put in for this oci was mostly edge 5/30 and some miles sb 5/30
