I'm new to gas engines and a friend in my club told me to be careful about which gas I should use. He said that recently, here in Canada, there is no longer ethanol free gasoline. Shell used to have ethanol free in their premium gas but it now has ethanol. According to my friend ethanol can affect the fuel lines making them stiff and brittle. A real problem especially for the lines in the fuel tank which have to be flexible for the fuel clunks. Ethanol free gas is sold in places like Home Depot but is expensive and is close to the cost of a gallon of glow fuel! Is there any way around this? Maybe a gas additive or different type of fuel line that is unaffected by ethanol?
