[QUOTE="69ST, post: 174532, member: 5"] The main issue is what it does to rubber parts, like fuel lines, seals and...for 2-strokes...carburetor diaphragms. With the carburetors on our 4-stroke Hondas, the worst impact is on petcock packings, the rubber washer/seal with all the holes. They'll shrink and turn brittle if allowed to dry, after being exposed to current formula gasoline. Draining the fuel system and coating the packing with a little grease, immediately after draining the fuel, will keep a packing viable for years. They still shrink a little, over the winter but will reconstitute and swell back to full, original, size within a matter of hours, once you refuel...cometh the spring. [/QUOTE]
