My 380SEL's oil gauge has started jumping around, this time last week it would always read full. Now it jumps to anywhere between empty and full... This in itself is worrying enough, but when the gauge reads empty the engine starts to rattle... and doesn't stop until the gauge returns to something above 1.

This sounds like a serious problem, so I'll be taking it to my tech, but I figured that it'd be a good idea to delve into the wealth of experience on this board and maybe save some time.

The oil resevoir appears full, and I can't find any leaks. Does anyone have any ideas?

Thanks,
Nic

are you talking about your oil pressure or your oil level? the oil pressure gauge reads from 0 to 3, and should probably stay pegged at 3 while driving. Is that what you are talking about? if it goes below 1 and the car rattles I think you might want to stop driving it until you get the oil pressure corrected.

Yeah, the oil pressure gauge.

have you had a recent oil change by any chance?

Not terribly recent. I've checked it again tonight, the oil is low, I've filled it some, checked my leads and driven it around the block. It's behaving better, but I'll make sure I get it checked anyhow.
