oil pressure.
 

When ever I get on it its right at 80. but then just a idle its right in the middle of 40 and 80. is 80 too high ? before it stayed right at 40 whenever i was idling ? why the change?

a lot of factors change this, but 80 is about right. oil psi is good ;D

To add to the OP's question, is there a such thing as TOO much oil pressure in these cars? I mean, if he's reading at 80psi, would that be considered "too much?" hehehe..I suppose if the "80" on the gauge was red in color, it'd be considered bad :D
