can you message me the info/link to your bypass filter? my oil psi seems normal, but again, the gauge can be faulty, as with my eng temp (dang thing will peg out either direction if i slightly rotate the gauge in the dash). as for an oap (oil analysis program, who do you recommend? i can't for the life of me, remember who we were using to test our acft oils and hyd, but i do remember they were in spokane, wa. but from what i was told, those people were not cheap ($75 per sample) and we have 2 engines, 3 xsmns and 3 hyd systems. that adds up quick. i was thinking of adding a lubrifiner (what i think you calling a bypass filter kit) and doing samples on my cummins p/u truck, even though its 2 yrs old and only has 16,000 miles on it.
