Reply to "High oil pressure"

bosswrenchMember

Tom, I once had a friend at Autozone who let me borrow 10 different oil pressure senders. I plugged them into my engine one after another. I got eight (8) DIFFERENT readings with the same engine, gauge and wiring! All 10 read lower than a mechanical gauge.

I added a tee pipe fitting to the back of the block and permanently added both a mechanical gauge (which are 2% accuracy minimum in the U.S) and the sender that read the closest to it. That was in 1981. The stock gauge is to tell me if I have ANY oil pressure. If I want to know within 2%, I open the deck lid and look at the far more accurate mechanical gauge.
