a. Test Course: Because of video restraints, a hard surface road was utilized.
b. Similar Products: No attempt was made to acquire and test every available product that available product that may have similar qualities. Militec was selected because it was readily available and was undergoing other tests within DOD.
c. M-151A2 Engine: A compression test and oil change with new oil filter was performed on both engines prior to the test and prior to adding the Militec. The compression test indicated that both engines were well within limits. Recorded mileage was 10,342 miles on the untreated engine and 3,585 miles on the Militec engine. Both vehicles were communication variants, therefore, no engine hours could be determined. It was decided that the engine with less mileage should be treated with Militec as the tolerances were probably closer, therefore, heat would cause the engine to seize quicker.
6.Conduct of the Test.
a. The initial step was to add 20 ounces of Militec to test vehicle "B" and drive the vehicle for 200 miles over normal highway and speed.
b. Both vehicles were driven to the test course starting area, a distance of l3 miles. This allowed vehicle operating temperature to be met as the outside temperature was 76°. Both vehicles had 150 pounds of sandbags in the rear.
c. Vehicle "A", the untreated vehicle, had its drain plug removed and all oil was drained in 4 minutes.
d. Vehicle "A" was then driven 13.5 miles as follows: 11.8 miles at 35MPH and 45 MPH for 1.7 miles. Road surface was blacktop, two lane divided highway that included curves and hills. A driver and the video operator were in the vehicle the entire time. At the end of this portion the vehicle had its drain plug removed and oil filter removed in order to remove any remaining oil. 1/2 quart of oil was removed prior to replacing the drain plug and oil filter. The vehicle was then restarted and driven at 35 MPH until the engine seized.
e. Vehicle "B" was started for five minutes, stopped, then had its drain plug removed for four minutes to drain all oil.
f. Vehicle "B" was then driven as in paragraph (6d.) . At the end of this period the oil drain plug and oil filter with approximately 1/2 quart of oil being removed prior to replacing the drain plug and filter. The vehicle was then restarted and driven at 35MPH until the engine seized.
