well im seeing about 30 at idle. 25ish when my oil is at 45% life. just making sure i got enough. 30 seemed low. but it all checks out now

After running around and getting things hot you still see 30? Thats real good

ya, 29-30. been like that since iv been paying attention. as the oil gets older it drops.

How are you reading oil pressure?

Oil pressure gauge. Put an autometer in my car.

Didnt know we had the ability to read oil pressure. Does it just read it off the OBDII?

I get 30-45 at Idle 60-80 crusing and 100-120 at wot, im measuring that with a glowshift red digital oil pressure gauge and I use castrol edge synthetic oil

you might be able to but corect me if im wrong I think the sensor in our cars is an oil switch which just turns on when oil pressure is not right I just installed an oil pressure gauge and sensor using one of the ports on the head directly under the exhause manifold, there are a few "how to" threads on here about it

No you can't read oil pressure through obd2. You actually have to put in a sending unit and all. It's actually easy though.

Got it. Cool ok. Thanks for the links.

I've been thinking about adding an oil pressure gauge myself. Glad someone brought this stuff up, I must've missed the original How To threads lol

Ok here's a question. Where is everyone tapping into. Mine is the hole on the from of the
motor all the way to the driver side.

^^^^ Picture would probably do more justice....just saying, lol

tomj77

iTrader: (2)

yes, im talking to the people with oil pressure gauges installed, cant read it any other way. tap into gally plug under the turbo, u need an adapter fitting

im guessing those higher numbers are when the oil isnt heated up

cmiller8006

iTrader: (3)

I am tapped into a plug on the front side of the motor.

cmiller8006

iTrader: (3)

See the three plugs on the front side, I used the one all the way to the right, it is where the oil pressure will be the least, so I know if I have good pressure there then the rest of the motor is great.

yeah that's one of the galley plugs. i did mine the lazy way. lol took out the factory sensor, screwed in the autometer metric adapter and put in the sending unit. has worked perfect for the last 10,000 miles

cmiller8006

iTrader: (3)

I was going to do that but didnt know if it would put on a light or anything.

BLAZIN07SS

iTrader: (7)

it didn't turn on any lights for me. i turned off all the oil pressure stuff in hpt anyway.

Mine is on the side of the block by Cyl. 4. Seems to work ok. i have a 2.4 i have 20 at itle once warm adn about 40 at 65-70. (2K-2500 RPM)

BLAZIN07SS

iTrader: (7)

mine at idle is ~25. cruising is ~55-60. wot is ~90

idk if the 2.4 is the same as the 2.0 but the one in the side, (thats if its on the head, reads low numbers, cause ur numbers seem a little low.
