I have a 83 RX-7 with a 12A engine. This car has always had good oil pressure around 60 on the gage. Recently I have noticed a drop to 30 psi and sometimes less. Any suggestions? The rx-7 has 149,000 miles on it and still runs good. Oil has been changed every 3000 miles. I would be thankful for any help.

 

Have you been checking your oil level or have you checked for any leaks?

It could be just an issue with your gauge.

 

Oil level has been fine and not one leak to be found!!

 

id get a new gauge(aftermarket) may be better than original.in that year oil gauge was electrically controlled so it may be the sensor and or gauge going bad..get a mechanical one with oil lines hooked to it and see what happends hope that helps...
