If you are looking for off-road to save money, beware. The Valeo by me (Lakeville) sells off-road a dime less than on-road which is $.20 more than what the Kroger's station sells on-road for.
I don't know what your fuel tax system is like in MI, but here in MO if we use on road diesel in an off road engine, we can get the fuel tax returned at the end of the year by filing a form to the Department of Revenue. last year we got back about $30 for our gas and diesel fuel tax.:2cents:
