....thank you for the information.

Richard L. posted the "quote" from the Wildcat site....
and truthfully I didn't go to the site to check it out....

...but the thing is, you know alot of people come to this
site, and to the internet in general to get information. A
person unfamiliar with engines and fuels could garner this
from that post....

I you put castor oil in a four stroke motor, this can happen:

engine gumming....
varnishing of the lifters....
coking of the valves....
sticking valves....
valve set knocked out of time....
improper valve seating....
reduction in compression....
incomplete combustion....
carboning at the exhaust port....

Sounds like pretty bad stuff.... ....personally, I've not
experienced those evils from using some castor in my
engines....but I only started running the four strokes about
14 years ago....and have been using the same brand of fuel
throughout.

Thank you for your reply, Jerry....
