Around here (ATL) the small engines will eventually stop running on E-10 and it takes a $100 carburetor cleaning to get them going. The cheaper the engine the more vulnerable they are. I am not aware of any manufacturers who are doing anything to adjust to E-10 at this time. One tank of E-free will tend to make the small engine run much better as will a dose of stabilizer in the E-10. We are told by the dealers to use E-free if possible. We are also advised to use the mid level gasoline. Seems to me that back in 56 when my 200 was made regular gasoline was about 87 octane and the octane was supplied by Tetra-Methyl-Lead. We are also being told by auto mechanics that E-10 will destroy an engine. I do not know but I will believe the mechanics over the E-10 lobby any day. My 200 starts and runs fine on E-10 and it starts right up in the spring or in the dead of winter as the case may be. These old girls will tend to run on anything from near kerosene fuel to 110 octane aviation fuel. Remember octane does not make the gasoline "hotter" but it is a "spark suppressant" so that gasoline can be used in higher compression engines without having pre-ignition spark knock.
