Oil Pressure

[Guest moose_320]

 

Having a little issue with something, not sure what it could be. The other week i change my oil and i noticed while i drive my oil pressure fluctuates like 5 or so psi. I replaced my oil pressure sensor a not to long before that becacuse, when i got the truck it was pegged at 80 psi. Right before i changed my oil i had the dipstick tube replaced because it was rusting away. Im not sure if something got in there when they were changing it or what, i never noticed it before i changed my oil. the truck has like 170000 miles on it so im hopeing its not my oil pump.

 

Let me know what ya think.

It does increase with acceleration, i know thats normal. if im driving its at like 45-50 but it fluctuates between 45-50 when the pedal remains the same. I did replace the oil pressure sensor so i was thinking maybe it was that, and at idle its at like 35 and it stays there. its the 6.0

it is normal to increase with acceleration. is that what is happening?

I know that minor fluctuation in oil pressure is normal for gasoline engines. I have two GM trucks with gasoline engines that both have oil pressure gages that show 0, 40, and 80 psi and anything in between. At idle they show around 30-35 psi and while driving they stay around 40-45 psi. I am not sure about what diesel engine oil psi should be but I know the gage should read exactly what psi is being given.
