Gauge readings.
Gauge readings. I just installed my Autometer 3-gauge pillar with mechanical Autometer Phantom Air/Fuel, Vacuum, and Oil Pressure. I just want to check with people to see if my gauges readings are correct for what they should be. Vac. at idle is about 19-21 in. Hg after startup, A/F dances all over the place (steadier at idle), and Oil Press. is around 42-44 when driving along (Using fresh Mobil 1 5W-30). The stock Oil. Press. gauge is reading higher than the mechanical Autometer one (around 50-55?). When I got on it hard, my friend was watching the gauge and said I peaked at a little over 60 on the mech. gauge. Vac. when cruising, just coasting often times goes upwards of 25 in. Hg. Do my numbers sound good?
