General LSX Automobile Discussion - whats does your oil pressure run at driving temature?

My oil pressure usually sits at about 36-38 at an idle after i drive it for a bit, is this the normal place for it, it puses about 45-50 when driving

That's good pressure, mine is around 60 driving and 50 at idle. Your good tho

i guess mine is 60 when driving, was thinking it whent up buy 10 instead of 20 lol

Mines usually around 45-50 at idle when the engine is warmed up and 60+ cruising. I also have a melling oil pump tho.

40-50 driving, 25-30 idle

Most of the LSx vehicles I've seen that have stock pumps idle slightly above 40 at operating temps.

today mine was ideling at about 35 afther a half hour cruise

My Z06 is 45 at idle my Formula is at 40

I idle at a stop around 22-25 with 38-40 driving

my idle its almost at 0 then driving it goes up

^ thats not good.....

40-45psi hot idle 55-60 under light load 65-70psi WOT Mobil 1 5w30 100*f florida weather.

I know I need a new oil pump lol

'98-'00 engines will have slightly lower oil pressure with the older style pump. A4 cars will also have slightly lower pressure at idle than M6s, as their stock idle speed is 250rpm lower in gear.

My '02 averages about ~5-10psi higher than my '98/'99/'00 cars did, all with the same oil and filter.

Im a hair under 40 at hot idle (2002 M6)

I sit at 40 at idle and 60 driving

I know I need a new oil pump lol

Sounds like you need new bearings too.

About 41 at idle, 60 driving.

Probably about 28 at idle, maybe 38-39 cruising stop light to stop light, doesn't go above 40 unless it's hard acceleration.. Is that ok?

I sit at 40 at idle and 60 driving

^^^this is mine and 80+ at WOT

How many of you have aftermarket oil pump, and when do you need one

Mine is stock. Car has 70,000 miles

my idle its almost at 0 then driving it goes up

Either your car is f*cked or your sending unit/gauge is wrong

But my ls1 is think is like 50-60 while driving. like mid 30s idle.

98 TA w/ 195k...25-40, 99 TA w/125k...25-40, 98 C5 w/95k...35-60, 96 SLP w/108k...30-60

thats what mine is. but im fairly upgraded.

i was under the assumption the relief would open right at 60psi even on aftermarket pumps. extremely high pressure is not good.
