So I spent a lot of time installing my antique Hawk brand oil pressure gauge into my 2005 Sunfire with a 2.2 Ecotec motor. When I started the motor the 80 psi gauge pegged!?! I shut it down and looked up the specs in the factory manual. "Minimum" pressure for a warmed up motor @ 1000 rpm is 50- 80 psi!?! Holy cow! That's crazy- I'm not used to that. In fact hot idle was around 600 rpm and the pressure was still 45 psi.. Is this the new normal? Some oil pump!
