Founded in 1958 by Claude Harnois, at the age of 24, the company's main product offering was heating oil

with customers primarily found in the residential and agricultural sectors.

Many years, partners and developments later, Harnois Énergies today serves the aviation fuel and lubricant sector in addition to meeting the needs of motorists and businesses

 for gas and diesel fuel and Mobil™ automotive, industrial and commercial lubricants. Harnois Énergies also offers its own line of specialty products under the H-Go brand, including Diesel Exhaust Fluid (DEF), antifreeze and windshield washer fluid.
