Not entirely true... I've run castor oil for most my life and what it
does is form a "varnish" that actually has intersting lubricity
properties. The varnish when cold is sticky and hard to remove. BUT
when it gets hot it starts sliding quiet nicely ime.

Sounds like you should have run a hotter plug and leaned it out a bit.
But that's just an opion that is worth every penny you pay.
