Oil Additive

Clean, improve and save with our FREE heating oil additive

Inside every gallon of heating oil we sell is a little something extra that offers you big benefits.

At no extra charge, we treat your fuel with a heating oil additive called HeatDoc, which continuously cleans and stabilizes your fuel. The result: a heating system that runs more efficiently with fewer problems.

HeatDoc helps:

  • Keep your fuel clean
  • Keep your fuel line clean
  • Fight inner tank corrosion
  • Increase fuel efficiency
  • Extend equipment life
  • Reduce or eliminate no-heat calls
  • Save you money!

When a tank is refilled with oil, sediment can loosen and float in the new oil. These loose particles can then contaminate tanks, fuel lines and even the components of indoor equipment such as filters and nozzles. Sediment or corrosion in a furnace’s firing nozzle can either reduce its efficiency or stop the burn completely. Beyond plugging, another effect of loose contaminants can be the corrosion of any exposed metal surfaces.

You know how expensive it can be to replace your fuel tank or heating equipment. That’s why you should keep your home heat-healthy with Jennings Oil & Propane’s heating oil deliveries with a free advanced fuel additive.

Additional outdoor-tank additive for winter weather

We also offer a specially formulated additive that combats seasonal challenges such as sludge buildup, gelled fuel, ice buildup, and more. It helps ensure a healthy flow of fuel oil even in the coldest Connecticut weather. Available at an additional cost, it is literally a small price to pay to keep your family warm all winter long!
