1. Remove the oil pan and place it on a workbench.
2. Level the pan flanges, front to back and side to side.
3. Pour 4 Qts. of oil or any other liquid into the pan.
4. Measure the distance from the pan flange to the surface of the liquid.
5. Insert the dipstick into the tube and measure the same vertical distance from the pan rail as step #4.
6. Mark the dipstick "Full" at the above distance.
7. Mark the dipstick "Add" 3/4" below the "full" line.

The oil filter canister will retain approximately 1/2 quart with the engine stopped so the oil level with 5 quarts onboard will read slightly above full after the engine sits idle for several hours. The dipstick will be accurate after about 10 minutes' run time and a shutdown.
