fluctuation

Convert dollars to Euros now, or wait a bit? Where can I research this?

Just had my oil changed for the 1st time ever. I always have done it myself but busted my shoulder and couldn't do it this time. The oil pressure gauge is quickly bouncing between 30 and 60 psi, when I accelerate. I never noticed it do this before, is it something to be concerned about? Don't...

oil pressure usually is in the center of the gage. sometimes the oil pressure gage is about 1/3 mark, never below that, never above the 1/2 mark.

...annoying, how do i fix it.? The year is 2000 and its a v6 4.3L. It revs up a little past 1000rpm and idles at bout 750. No irregularity in temperature or oil pressure. However recently i have felt less pick up in the accelerator.(related?) Thanks
