Hook up a mech. gauge. It should read about 30 PSI, hot, at idle. Also hook up a scanner to see if you have codes.

ive noticed it since i put on my new rims and short shifter and k&n. i did them all at the same time. (im not sure when the oil pressure went so low just the power offness)

maybe my oil pressure isnt THAT bad, im down like a liter in oil would that change it?
