[TR] Oil to free an engine

[Andrew Uprichard]

It's it amazing how one can skip across a thread when it doesn't bear upon
anything relevant in one's TR life.  I know the answer to my question has
been addressed before, so I apologize, but I just bought a car with a
supposed rebuilt engine (aren't they all?) which is just "a little stuck"
from sitting.

What is the magic oil people use to free up a frozen engine?
