#PIP4690D: Normal Characteristic - High Oil Pressure Gauge Readings - (Oct 16, 2012)
Subject:Normal Characteristic - High Oil Pressure Gauge ReadingsModels:2010 - 2013 Chevrolet Camaro
Equipped with 3.6L LLT or LFX Engines
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Some owners may comment that the oil pressure gauge is indicating that the engine appears to be operating with very high oil pressure.
Recommendation/Instructions
Under various engine operating conditions 60 psi (413 kpa.) of oil pressure may be displayed on the oil pressure gauge. This should be considered as normal operation. In addition, during a cold engine start-up (especially during cold ambient temperatures) the oil pressure gauge may display at 70 psi (482 kpa.) or all the way to the right. This condition should also be considered as normal operation. As the engine and oil warm up, the gauge should begin to return to approximately 60 psi (413 kpa.).
Important: Because these operating pressures are considered normal operation, no repair attempts or parts should be replaced.
Customer Information
