What is the normal operation range for the oil pressure in the T-6?

The normal operating range for oil pressure in the T-6 is indeed 90 to 130 psi. This range is critical for ensuring adequate lubrication and cooling of the engine components. Within this range, the oil pressure maintains sufficient flow through the engine, preventing damage and ensuring proper engine performance.

Operating outside of this range, particularly below the minimum pressure or above the maximum, can lead to inadequate lubrication or potential overheating, which can compromise engine integrity and reliability. Thus, maintaining the oil pressure within this specified range is essential for safe and effective flight operations in the T-6.
