I made my trek to the Toledo R/C show Friday April 4, 2008. I stopped by Eric Clutton''s (Dr. Diesel) booth a picked up two gallons of diesel fuel at $ 25 a gallon. He now only sells one mix and not the two he used to market in order to keep costs down. No more ball bearing and plain bearing mix. I usually at a bit of extra castor for break in and some extra ether for small engines anyway. Jack
