I disagree. The vast majority were triggered at 20 psi. This coincides with information that states "The ideal oil pressure varies depending on the car brand and model, but generally, the ideal oil pressure is between 25-65 PSI. Sep 9, 2020".No, more isn't necessarily better. GM's low pressure warning light switches were calibrated at 3PSI for many years. Nowadays, gauges are not true gauges, but "discreet" in that they display in a normal range at or above very low thresh holds.
One good example was the 2.8Liter V-6 engine which went through many iterations over decades. In it's early, carbureted form, 3 PSI was factory minimum threshold for the light to come on. My 1986 Pontiac 6000 station wagon had this engine, as did many vehicles produced in those days, including S10 pickup trucks.
As the years went by, the size displacement and fuel controls morphed into more modern v-6 engines in the Malibu and Impalas.
Longevity was never any issue due to the fact that upon rev up, the psi went up with the increase of rpm.
Use some deductive reasoning, if near zero psi was really good, then why would any vehicle have ANY warning lights or gauges at all?
