With that kind of compression, how could he NOT be burning oil!

One question, when running compression tests on cars, do you have to have the throttle wide open...like you do on bikes? I had a friend who once got low numbers when testing his bike. Then I tested it and the numbers were fine. Came to find out that he didn't hold the throttle open.
