Adding E15

With the current state of the gasoline and retail industry in the United States, many factors go into determining the success of capital investments by retailers. Gross margins, fuel volumes and traffic patterns all contribute to successful fueling stations.

One place many retailers start is by planning on including E15 in their new build or scrape and re-build plans. More terminals are offering pre-blended E15 making access to supply easier and easier to obtain.
