My car does this but it's just cuz the gauge grounds out somewhere along the line. I know the engine is fine, and the gauge reads fine from time to time, so I really don't pay it much attention...well...I don't pay it any attention, actually...lol

I know you have a Cavi...I'm not familiar with these cars and I have heard a ton of bad stuff about them so I don't wanna say it's just your gauge, but do you think this is a possibility? If I were you, I'd check my oil level, make sure the engine isn't smoking, listen for valve noise and just wing it if all that checks out. Honestly, I wouldn't really worry unless the little oil light comes on...THEN you KNOW you're REALLY getting no oil pressure. Just a thought, man. Good luck.
