I'm getting ready to fire mine up but I have to get some tubing, Is the Flexable dubro 1/8" of 3' tubing a good choice for $3.89 or is ther better or cheaper tubing at a lower cost available from auto parts store or speed shop. Also I was told the AMS Oil Synth 2000 50-1 oil was the best to use are there any other brands that are as good but cheaper that you can get from the Motercycle shop.

Do these gasoline engines need after-run oil like glow engines do.
