Default RE: low oil pressure!!!

Your oil pressure is fine, you only need like 12-15 at mostidling and 50 or 60 at driving speed. A lot of people don't feel comfortable unless they have like 90psi. If you're really that concerned just change to the next weight up oil, 10-30 go to a 10-40 etc. But if you can nail the gas in a lowergear at idle-1,200rpm and it doesn't knock/rattle/lug etc, then you're fine.

ORIGINAL: nyfreakinrican7

I like the whole terminal idea you have. My original push on connector was giving me problems but I just spliced another push on one from a junkyard car. Yours is secure cool. And my engine has a fresh rebuild and after the car is warm at idle the pressure drop considerably
yeah mine kept falling off and i would look at the pressure and it was all the way down i would freek out pull over and see it came off. so i spiced one of those on instead works a lot better. after i put it back on tightened it down and drove it was back up half way into normal like it usually is. my car has 178k on it no major issues ever really

get that fixed asap

my sending unit was loose and i taped it up, that same night the thing cracked open and was spitting oil out while i was goin 80mph down the highway

my car was COVERED... top to bottom in oil.

that was an interesting night.. WOT im at about 70 psi (autometer mechanical gauge) so the engine has some life left in it...

i threw in a bottle of lucas and nearly doubled my old oil pressure at idle.

lowest ive seen it go to yet after hours of driving was 38 at an idle

before the lucas... about 20 psi.. maybe lower.. it was bad.
