An Engineer/truck builder told me to use 20w50 oil i have 200k miles it sent my oil pressure gauge to 79 psi. With 10w30 i run 65psi "IS IT SAFE" My engine seems to like 20W50
But i don't need blue-smoke.

Engines less noisyWhy do you think your engine likes 20/50? 65 psi is more than plenty oil pressure.
The standard gold-accepted rule of thumb for good acceptable oil pressure is 10 psi for every thousand engine rpms. 65 psi was MORE than good psi. I personally would never run a 20W-anything in my TJ. 20W when the engine is cold just means that oil takes a lot longer to get circulated through the engine, especially in colder temperatures.An Engineer/truck builder told me to use 20w50 oil i have 200k miles it sent my oil pressure gauge to 79 psi.

My $380.00 1983 ford Escort Diesel ran with 250w bulb till i parked over night on top of a mountain in -4 degrees. Tried to start it by pointing car down hill. At 40 MPH popped clutch and chunks of engine are still on side of that Mt,Putting a 120v 250 watt incandescent spotlight bulb directly underneath the engine and plugging it in over night would avoid that issue. Of course I haven't seen that done on anything since winter in the early 1980s when my neighbor wanted to be able to start the Golden Jubilee to plow the driveway.

That out the door, for this jeep It's been a week with 20w50 and all knocks, taps, and bangs are gone.10w-40
I wouldn't run that in cold weather.That out the door, for this jeep It's been a week with 20w50 and all knocks, taps, and bangs are gone.
Keep us informed of your continued results. It would be interesting to see the results.That out the door, for this jeep It's been a week with 20w50 and all knocks, taps, and bangs are gone.
