hey guys, stupid question which i should know:loser:, what should my blazers oil pressure be at? this is th third blazer (all 4.3) ive owned and my oil pressure is dirrerent from the others. i use fully synthetic 5-30. and the pressure while driving is just below 40. and at an idle around 20. below 40 at highway speeds just seems low? the engine seems to be in real good shape ( No leaks, doesnt burn oil, doesnt knock) i just have to ask for peace of mind:rolleyes:. thanks much, jim

Are you using the dash gauge, or have you installed a manual gauge for testing? The dash gauges are more for looks than diagnosing problems, (they're not real accurate).

I'm going off the dash.
