A bunch of motorcycles made before the beginning of E10 have fuel tanks that are made of a material that swells and deforms with E10 gas in it. If you have a 90s or early 2000s Ducati, E10 can make it impossible to remount the tank after removal (which has to be done for lots of service.). I stay away from E10 when I can because several of my bikes have 'plastic' tanks, and I worry what could happen to them. Replacement tanks are not cheap.
