Fuel Oils

History in the making for more than 83 years, White Mountain Oil & Propane has been in the fuel oil business since 1941.

We deliver premium #2 ultra-low sulfur heating oil, K-1 kerosene, diesel and gasoline products. Heating oil is widely used throughout New Hampshire and Maine as a primary energy source in homes and businesses. More than 59% of all homes in New Hampshire heat with oil, according to the Energy Marketers Association of New Hampshire. 

Oil heat is a safe, dependable, economical and comfortable energy source. Research developments have allowed oil heat to conserve more energy over the years and provide clean-burn technology which makes oil heat the smart choice for consumers who heat their homes in northern New England.

Other Fuels

K-1 Kerosene

Kerosene is used primarily in “Monitor-style” heaters  such as Toyotomi and Laser brands and in mobile home furnaces as well as construction heaters. Kerosene may be used by any oil-burning piece of equipment but is especially required by certain types of heating equipment. K-1 kerosene (the type used in northern New England) is simply a more-refined level of heating oil. K-1 kerosene will not congeal during extremely cold temperatures and is often used in outdoor tanks. White Mountain Oil & Propane has been in the kerosene business since 1941.

"Off-Road" Diesel

Off-road diesel is the same quality as our regular blended Ultra Low Sulfur Diesel, except it is free from State and Federal road tax. Off-road is restricted for use in non-mobile pieces of equipment (generators, industrial machinery, etc.) or strict off-road use (such as logging equipment) and is delivered by us year-round.
