Hello everyone,
Ever since I changed over to 20w50 VR-1 with a black WIX filter on my 440 my oil pressure light comes on randomly while driving. I have a mechanical gauge too and it is always good with around 40 psi at idle 50 at cruise and 60 under load. Could the sending unit for the light just be old and not like the heavy oil?
