Oil doesn't burn off. It carbonizes and becomes a molasses like
substance which is almost impossible to get out. If you use ordinary
motor oil in air-cooled engines in very hot weather you will discover
this quite quickly. To avoid this, I use motorcycle oil in my
air-cooled engines. It is formulated for very hot use.

Did you really think that a small amount of synthetic is going to make
the other 4 quarts of regular motor oil not do what it was doing before.
I think not. Otherwise, why not just use 90% cheap oil and 10%
I saw the same weird use of oil happen once in a friends Dodge. It was
speed dependent. Above a certain speed the engine blew or burned oil.
Below that nothing happened. He was in a big hurry going from PA to NM
and carried and used oil in bulk. On the return trip, he took time to
smell the daisies and didn't use any oil. That sounds more plausible.
