hellcat 05-10-2005, 02:56 PM Around 30 at idle and 60 at speed is normal. marcdeluca 05-12-2005, 01:47 PM If you think it is low, hook up a mechanical gauge and check it. My dash gauge reads 20 lbs low. There is a plug on the oil filter housing that is easy to pull to hook a gauge to. dale25 05-12-2005, 03:26 PM spec is 14 lbs. hot at idle. | ||
