System Oil Temperature:

Finish oil temperature (Test 6) must be within 10 percent15F (-9C) of start oil tem-

perature (Test 2).

For each 15 degrees that the finish oil temperature is higher than the start oil tempera-

ture (Test 6 greater than Test 2), subtract 0.5 gal. from the leakage rate.

For each 15 degrees that the finish oil temperature is lower than the start temperature

(Test 6 less than Test 2), add 0.5 gal. to the leakage rate.

Low Differential Calculation:

Test 4 = Test 3 - Test 4.

Test 5 = Test 3 - Test 5.

Percent Flow Loss Calculation:
