Yes, its up to owners to make a wise choice.

The greasy black stuff coating everything inside the motor had to be seen to be believed.

A Dommies engines' insides.

The thick greasy black coating had to be experienced. Unused since the early 1950s ?
It did keep it rust free though !. Bearing has been cleaned.
Detergent oil would likely unleash all of that into the lube system...

It's not that bad, the crank's in one piece, cam doesn't look that bad.
Clean up and a set of rings will probably put it right. Just like with your old ford popular.

Nick is right, cleaned up perfectly. Note that the bearing is already cleaned, I was curious as to its survival
Thats EXACTLY why you don't just pour modern oils into older engines WITHOUT CLEANING THEM. !!!!!!!!!!


You should see inside an engine that been run on old style Castor-based oil,
EVERYTHING is coated in a strange yellowy rubbery sticky coating.
Its impossible to wash off, its impossible to blast if off (and you wouldn't want to anyway with internal components)
quite difficult to scrape off and where its baked on its really baked on.
And probably still in perfect condition underneath.
And you sure wouldn't want to add modern oil into that ...

Oils ain't oils, Sol ...
