The TANK-GUARD® Program is a corrosion protection and warranty service for aboveground fuel oil tanks up to 330 gallons capacity. With this program, we offer our customers an effective chemical corrosion inhibitor plus the security of our “peace-of-mind” tank replacement warranty.

Experts recommend using a chemical corrosion inhibitor to reduce internal tank damage. Our program is a cost-effective way for homeowners to protect their tanks against internal corrosion. It also provides a welcome and valuable warranty benefit if a tank needs to be replaced. With today’s oil prices, the unexpected cost of replacing a tank is the last thing a homeowner wants to worry about.

Regarding customer satisfaction, there is no question that the oil tank is often the Achilles heel of an oil heat system. Even with today’s technology, predicting when a residential oil tank might leak is unrealistic in any practical sense. But you can still work proactively to protect tanks against corrosion and be prepared to cushion the financial impact of tank failures. That’s precisely what the TANK-GUARD® Program will do for you.

Why Choose TANK-GUARD®?

Although standard steel heating oil tanks are renowned for their strength and durability, they inevitably reach a point where replacement becomes necessary. Typically, the culprit is internal corrosion, which gradually occurs due to natural condensation over time. Unfortunately, most homeowner insurance policies and oil dealer service agreements do not include coverage for oil tank replacement.

Enter our proactive TANK-GUARD® Oil Tank Protection Program. This program ensures that eligible tanks are shielded from the harmful effects of internal corrosion by applying an effective liquid corrosion inhibitor, thus reducing the risk of tank failure. Moreover, when your tank is registered in our program, you also benefit from substantial financial protection through our generous tank warranty if tank replacement becomes necessary.

A solid tank replacement warranty backs TANK-GUARD®. If the TANK-GUARD® warranty covers a tank leak, your oil tank will be replaced at no charge (parts and labor). Removal and certified disposal of your old tank are included. Your oil tank is a vital heating system component and worth protecting. With this warranty, the TANK-GUARD® program offers complete tank protection. Oil leaks can be severe, so please check your oil tank regularly and call Hillside at the first sign of any leak.

Frequently Asked Questions

Why do heating oil tanks fail?

The most common reason for heating oil tank failure is internal corrosion. All heating oil tanks, including indoor ones, are vented to the external atmosphere. Moisture in the air inside the oil tanks, even in indoor settings, condenses over time. This moisture, which accumulates as a small amount of water, is denser than oil and settles at the tank’s bottom, forming an acidic sludge. Over time, this sludge can corrode the metal through oxidation (rusting) or electrolysis (pitting), eventually leading to leaks. These leaks typically start as slow seepage or dripping. If you observe such a leak, contacting your oil heat dealer promptly is crucial. Place a container or pan beneath the leak, but avoid touching or wiping the affected area.

How does TANK-GUARD® work?

TANK-GUARD^® corrosion inhibitor is a water-soluble concentrate. It does not mix with the large quantity of oil in the tank. It mixes only with the relatively small amount of moisture and sludge in the tank bottom, where it serves as a neutralizing agent and helps to impede further corrosion.
