: : it's not like a fluid level sensor..but it's stuck in a oil passage (to/away from filter). so the oil has to travel the passage and to the sensor (some psi behind it)..if psi drops i would assume the oil will stop traveling to the hole in the sensor and then it'll light up...but how much psi loss is that? no clue.

: : : Ok I understand it just provides a ground, but I would think it should have a pressure rating. It's not light a fluid level sensor, like the ones that might be in a radiator and if the water drops below that sensor it will trigger a light. Since the switch is in the oil pressure flow it has to has a pressure rating. Maybe the minimum pressure rating is so low, all the oil will be gone before the light comes on just as you stated.

: : : If someone is aware they have a minor/moderate oil leak they will check their oil level more frequent, BUT if for some reason you're cruising around and all of a sudden you have a moderate to severe oil and it's day time you may driver several miles before noticing anything, that sucks.

: : : If we can have this light turn on at 20-25psi instead of 0psi I don't have to say how benificial that will be.

- Any performance shop can sell you one of those. Also found in nitrous kits, etc. EASY to find. n/m The Max (92 J30 Maxima (turbo project underway)) 18:52:13 7/06/2002 (0)
