GenIII if you have that in your oil that is possibly causing the oil pressure issue. im not a fan of additives but try some seafoam thru the motor. you need to clean that motor. i think you can run seafoam thru oil. i would run it then instantly change the oil again after all the gunk is out. keep repeating this using cheap oil so you dont go broke.

but get yourself a leakdown tester if you can and see if motor is all within spec. that much sludge worries me.


i also dont like mobil 1 oil at all
