Dedicated to Northeastern Montana and Northwestern North Dakota since 1970.

Matthew W. Miller and Kevin G. Miller purchased Miller Oil Company Inc. from their dad in 2016.  Their dad, Gordon W. Miller, started the business in 1970.  Matthew and Kevin have been involved in all aspects of the business their entire life. 

Miller Oil currently has two bulk plants in Montana.  One in Culbertson and one in Plentywood.  We deliver gasoline, diesel, propane and oil to many areas in Eastern Montana and Western North Dakota.  We service oil companies, farmers, commercial and residential customers.  We have a cardlock location in Plentywood and three locations in Culbertson.  We also sell water heaters, furnaces, and central air units and can service what we sell! 

In 1997 we purchased the underground utility propane system in Culbertson.   This part of our business is “The City Line”.
