Dipstick Calibration

This shows the dipstick installed fully screwed in. The Roper Plate shows where the gasket level is for reference.

Filling with 3.5 liters of oil, as specified by the manual and new filter brings the level to .69 inches above the dipstick full mark. In my opinion, that should be the full level without the Roper Plate. My oil pressure gauge test showed that without the Roper Plate, even with 4 quarts, the pump starves under maximum acceleration in first gear from a rolling start. With the Roper Plate, refilling with 4-1/2 US quarts is still safely below the plate, and no oil starvation occurs even with 4 quarts.

Long, hard accelerations up steep hills and/or wheelies, may still cause starvation. I have not done these tests.
