2008 Oil pressure issue?
My oil pressure gauge seems to be all over the place.
The 12:00 position is 275, there is a 3/4 between 275 and 550, and a 1/4 position between 0 and 275.
As soon as the engine starts, it reads almost 3/4, then after the engine warms up, about 3-5 min, it is right at the 12:00 position. (Where I think it should be) After that, sometimes when I'm stopped at a red light idling, it reads almost down to the 1/4 position. As soon as the engine revs up, it goes back to the 275 mark.
I'm just wondering if anyone else with a 08 or 09 can tell me what their oil pressure gauge reads?
Is it worth taking in?

I'm having occasional problems with my 2006 HS. Last December, for the first time the Low Oil Pressure warning light and tone sounded. I immediately checked the oil level and it was fine. The engine sounded normal. The warning went away. A few days later, it happened again so I replaced the Oil Pressure Sensor with an OEM brand and that cleared the problem for a few months. No, 5 months later, it still goes off occasionally. Any suggestions?

Hey guys, who I just hammered out this pressure problem. I have a 2005 h2, and mine would vary from 0 to maxed out 80 psi. Here's what I found.
After replacing the switch I had no change. Come to find out, it's read off voltage. NOT actual psi. 0 psi equals 0 volts. @12 volts it's around middle or 40 psi. So at the end of the day, if you have any voltage problems, it will read out in your oil pressure. I had a short in the wires going into the pressure sensor and once fixed, I had normal pressure again. Now with that said, it's completely normal to run between 25-60 psi. When cold, it should run around the middle to upper 3/4. When hot it may run 1/4 to half. Never down to zero. If it's goes to zero or to max, check your power output from your alt. If you have a huge load (lots of aftermarket lights and subs and things of that nature) it may well be a voltage issue, and not an oil pressure issue. I ripped my hair out trying to figure this out and hope I helped someone.

I would have never thought of that being the problem,good find. I will have to look into my alternators performance.
