DanO, it does at _very_ high temps, above 300F. That wasn't part of the
discussion (and needed have been part of the discussion) until some poster
incorrectly stated that only multi-grade oils did this. It is a probable with
all petro oils.

yet, yo-yo, the fact is the statement was made that multi-grade oil
tickens up
at ****very high temps*****
AAAAAAAAAAAAAAAANNNNNNNNNNNNNNNNNNNNNNNNNNNDDDDDDD DDDDDDDDDDDDDD this is a
reason to use single weight oil.

sorry, dood, but single weight oils thicken up under the very same very
high
temps, so the arguement is specious (look up the word).


Guys... oil does not thicken when you heat it up.
