my oil pressure drops to 20 about 5mins. after driving it. anything wrong with that???

 

Personally I don't think so, mine does the same. however for peace of mind I'm installing a new oil pressure sensor, these have a tendancy to lose accuracy over time.

 

nope thtas normal with the lt1. as the oil warms up the pressure drops. 20psi is well with in gm operating range.

 

yes if the pressure being low bothers you that much change the sensor, how many miles are on your car? and whats the weight oil your useing?

not sure if this was address to me, but I'll bite

Just want to be on the safe side, I'll feel much more at ease if the gauges were just a bit more accurate.

Oil, Mobile 1, 5W30 only. never used anything else.

Miles, approx 150,000. still runs great!

the high mileage is one of the reasons I'm puttnig in the new oil pressure sensor. The other being, that a cam, roller rockers, lt4 timing chain and fuzzy dice are on their way..
