What is the normal hot idle oil pressure for a Chevrolet Corvette C7?

For a C7 Corvette, normal hot idle oil pressure is typically in the high 20s to low 30s—usually hovering right around 23 to 30 psi when oil temperatures are in the 190°F to 200°F range ⁵.

If you have a manual transmission (M7), your idle RPM is a bit lower (around 600 RPM), and it's completely normal to see pressure dip into the high teens (around 19 psi) if the oil temperature climbs up toward 220°F ¹.

If these numbers seem low compared to older platforms like the C6, that is by design. The LT engines in the C7 use a computer-controlled, variable-displacement oil pump. Instead of running high pressure all the time, a solenoid adjusts the pump's output based on engine load and RPM to reduce parasitic drag and improve efficiency ⁹. You will also occasionally notice the pressure spike briefly during steady cruising shortly after a cold start; this is just the dual-displacement system running a self-test ⁵.

For reference, the factory service manual lists the following minimum acceptable hot oil pressures ⁹:

• 1,000 RPM: 22 psi
• 2,000 RPM: 30 psi
• 3,000 RPM: 33 psi

As long as you are seeing high 20s at a warm idle and the pressure climbs smoothly into the 40s under spirited acceleration, your system is operating exactly as intended.
