I got a 95 Chevrolet k1500 with new trans. Motor was put in about 7-8 years ago and has miles according to regular driving 140k-160k I’d guess. Stock as far as I know on internals and the rest except the MPFI system.
Cold start (even on a warm day) oil pressure reads 70 psi and will hold there even if I let it warm up for about 5 minutes and drive it will hold there.
And then after it warms up for a while it will hold 40-55 psi at idle and then up to 60-70 psi while driving.
I am on first oil change since I got it still (changed august 20th) and I went with 4qts of Shell Rotella convential 10w30 and 1qt of Lucas oil stabilizer. (Did it mainly for a clean out on first oil change and I am going to send it in for an oil analyze at black stone labs)
Previous owner (a friend of ours) got oil changes every 3,000-5,000 miles and used a 10w30 valvoline.
I daily drive this truck and have been since I got it, I have heard no odd noises at all. I thought I heard a knock on startup some times but I don’t think it could be because it is a lot quieter than a “knock” would be and it’s a hit or miss, sometimes I think I hear it and it ends up going away and other times I don’t.
anyways I’ve read that it’s normal in some places, others not. But really not sure.
