Fuels for Home - Dowler-Karn

Fuel is an aspect of daily life – at home, on the farm, on the road, and at work.


Whether you need HEATING OIL for your home furnace, DYED-DIESEL fuel for your farm equipment, or DIESEL FUEL for one generator or an entire fleet of vehicles – Dowler-Karn has the fuel solution and the service to meet your needs.

Plus, we offer quick and convenient 24-hour Fuel Access Centres at 9 locations throughout Southwestern Ontario.

For added convenience, we have automatic and tank-monitoring delivery options available for our fuel products.

Automatic Delivery

You can count on worry-free delivery from Dowler-Karn.


Our Automatic Delivery is one of the most popular services we offer.

Our delivery system is based on “degree days”, which means we deliver energy based on outside temperatures. In other words, we know with a long spell of cold weather, you will use more fuel to heat your home or barn. This method makes sure we keep you topped up. Typically, furnace oil customers will see a Dowler-Karn delivery truck about six times per winter.

Tank Monitoring

Customers whose operations are heat critical or who are large volume customers may find tank monitoring to be the best solution.


This is one way Dowler-Karn will remove the worry about the level of fuel in your tank. For more information, contact a Dowler-Karn Branch near you!
