really stupid question

Is it plausable to modify an older oil injection system for castor
instead of dino oils? It's a crazy thought but I have my reasons.
Least of which I prefer the high temp lubircity properties of castor
over the other choices.

OK, so vegetable oil runs to the heat and lubricates for that reason.

Unfortunately, engines aren't always hot and the excess castor oil
will
turn to black gum that will glue your piston rings in their grooves
and fill up the exhaust port with carbon and will also plug up the
baffles in your mufflers.

I wish somebody had told me that racers tear down their engines after
every race meet. I could have saved myself a whole bunch of hassle
with the carbon deposits plugging everything up.

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.

If you use a hot plug with the baffles all plugged up with castor oil
mung, you will burn a hole in a piston.

Don't ask how I know that...

Also, I was embarrassed at a motocross track when the Husqvarna
factory team was asking me about the track and my Yamaha 250 MXer was
running like a 125cc machine with its piston ring stuck in the groove
from using castor oil.

Odd, because even when I was <mumble,mumble> I pulled the baffles
quarterly on a T-500 and cleaned them. Even though we were only
running dino at the time.

Feaces occurs dude.

You do know you can use a little less castor than dino right? My
nominal decades ago was no more than 18% and sometimes a bit less if
it was getting close to a new top end (new piston jug set and ain't
aircooled fun?)

Still my question was an idle one and I'm not surprised anyone had an
answer either way. I mean it is a rather insane idea, innit?

Amsoil is the reason I got 160,000 miles on my 1977 Wing before I sold
it, in 1997!
