What should the oil pressure gauge read during normal operations of the T-6?

During normal operations of the T-6, the oil pressure gauge should read between 90 to 130 psi. This range ensures that the engine's oil system is providing sufficient pressurization to lubricate engine components effectively, preventing excessive wear and overheating. Maintaining oil pressure within this specified range is crucial for optimal engine performance and longevity, as it indicates that the oil pump is functioning correctly and the oil is circulating properly throughout the engine. Lower oil pressure may lead to inadequate lubrication, while excessively high oil pressure could indicate potential issues with the oil system. Understanding these limits is essential for safe and effective aircraft operation.
