I used that crap in a 1956 Jeep wagon I built, in which I had installed an 
AMC 6 cylinder engine.

I completely wore out the engine within a year. Oil pressure at idle was 
something like 5 lbs by then.

I would never, ever, use it in anything I intended to keep ever again.

That "oil" is a very bad idea. Graphite IS an abrasive, period.
