Re: First Technical Question - Islero Oil Press Gauge

Hi Udo, I switched off my factory electric oil gauge about 19 1/2 years ago after I was displeased with what it was telling me.I installed a 200lb mechanical gauge just above my right knee, and I watch it religiously. What I noticed is that it is far more stable and accurate than the factory setup.I can now see, in detail, exactly what is going on with the oil pressure. My 400 typically idles at ~25lbs when warm, and runs ~80lbs most of the time I"m cruising.I can clearly see the cutoff valve come on at ~120lbs, and the various other fluctuations. I"d guess your factory setup could be cleaned up, dialed in and would work just fine.But if it was my car, the first thing I"d do is go to a speed shop and order a 200lb mechanical gauge and wire it up to check what is really going on in the engine. I imagine there is a way to run both at the same time, but I simply disconnected the factory gauge. Let us know what you decide to do.I"d be interested to see what the mechanical figures are. All the best, Fred 67 400gt 2+2
