Oshkosh and Wiscona Pep Engines

Many of the best-known engines came from Wisconsin. So did many of the least known, including the Oshkosh and Wiscona Pep.

The Wiscona Pep’s signature is its unique water hopper, cast to accommodate twin fuel tanks either side, one holding regular gasoline and the other kerosene. The engine could be run on either.
