RE: COX .049 plane engine Fuel
Nope, no longer made. Just old ad's I've collected to show how they played with the formula. I always thought it had been castor because when I had stopped as a youngster it still was, but now able to look back at the years i've missed I seen they had used synthetics for a period. Seems like the time just before being sold off to Leisure Dynamics. Probably to help lower cost, and appeal to other fuel users.
