Test Parameters

Test engine: 3W-42 (1/2 of an 85) which was well broken in. The cylinder was
removed and the piston, ring and inside of the cylinder was cleaned of
carbon. The picture of the piston is a typically cleaned piston before the
start of each test. The engine was reassembled. This process was repeated
before the start of each new oil test.

I think everyone should respect the toughness of the test engine. It is
hooked to an immovable object, runs full bore with too large a prop for 6
hrs straight with temperatures near the acceptable maximum. This engine has
churned through 30 gallon of gas/oil mix, run for 58 hrs and never missed a
beat. It is running just as strong as when I started. I think one could call
this test, engine abuse.
