Wisconsin Boating Alerts:

E15 now at Pumps in Wisconsin - Buyer Beware

Testing by the DOE has indicated that higher blends of ethanol such as E15 can cause engine failure in marine engines and currently Wisconsin sells E15 at the same roadside gas pumps where you may fuel your trailer boat. E15, or gasoline with 15% corn-ethanol may also be enticing because it is commonly the lowest-priced fuel at the pump. Please make sure to take a good, long look at the pump before selecting fuel for your boat. Currently there is no marine engine warrantied to run on any gasoline fuel containing over 10% ethanol.
