Hello,

The problem started today, my oil pressure guage is fluctuating. At idle its about 40% and at cruising speed at 70%. Before it was always at 60% to 70% steady never fluctuated. Did a search and noticed it was normal to see 20 to 30 at idle and 50 to 60 at crusing speed. Bad sender, bad gauge?

Thanks

Generally a going bad sending unit. I'm trying to figure out how to test the gauge. I replaced my sending unit and it still has problems.
