    6.2 LS Oil Pressure

    What are you guys seeing for oil pressure readings on 2018 or so 6.2 LS engines?? Mine seems low but I have no experience with those engines. Not sure I like 0 - whatever weight oil either.

    Lots of high mileage vehicles have an issue with the "O" ring at the suction tube for the oil pump hardening and causing a leak.
    Requires dropping the pan to access.

      How low at idle ? What's the pressure at 60 mph ?

          Idle pressure seems a little low, is that when it's warmed up ? Mine shows at idle when cold about 35, once it's warm about 25-30. I notice my pressure is higher after I change my oil. GM would tell you that's OK. Your pressure at 60mph seems to be normal.

            Warm at 25 psi or so. I may bump up the oil to 5 - 20 weight or so
