I've had my Subi for about 2,000 miles. The oil pressure gauge has always fluctuated pretty wildly from near 0 all the way to 75. I know there is some normal fluctuation with accel and decel, but this seems excessive.

 

Do most of you maintain pretty steady oil pressure? Am I about to fry my engine?

My op gauge does the same thing. It usually stays @ zero but every once in awhile it will jump to 75 then back down then back up and on and on. I think mines electrical though , I don't even pay attention to it anymore.

Most likely the sender (at the oil pump), mine whent crazy a few weeks ago, scared the crap out of me when it droped to 0 on the freeway. I put in a temporary mechanical one to check things out… pressure is fine, sender is junk (I can see oil seeping out of the electric screw).

it probably is a sender or something like that, but

I do have oil pressur eproblems with my Jeep. I think I have crud in the oil pan that gets sucked up to the mesh before the oil pump. Right around 3000 miles I start losing oil pressure. When i step on it the ressure drops to near 0 and it sounds like a diesel truck.

To cure this for the time being, I pour 2 cans of engine flush in and let it idle for 30 min before I change the oil. It does the trick.

This is probably not your problem, but maybe some one can benefit from my temporary solution.
