Harvey Wagner started Wagner Oil in the 1950's as a gas station dealer with a bulk fuel delivery route with Cities Service Oil Company. Harvey built up the fuel delivery over the next decade, while his son Howard grew their service station business in Antigo.
In the late 1970's, Howard built his first C-Store in Wittenberg. A third location was added a few years later in Oconto. At this point in time, Wagner Oil sold around 4 million gallons per year as a Citgo wholesaler. Howard purchased his 1st transport in order to transport product to the 3 stations and Wagner Oils bulk plant.
This was the start of Wagner Trucking Company.
