Heating Oil Treatments

Best in Class Heating Oil Treatments

At Fuel Ox, we understand the pressure that comes with keeping your fuel oil system running throughout the heating season. Your heating oil needs to perform every single time you flip that switch, and that means using the right heating oil treatment to prevent issues like wax buildup, bacteria, and oil sludge that forms inside your storage tank. Our Star Plus heating oil additives are made to treat all forms of heating oil – those with and without bio content.

Our Star Plus line of Heating Oil additives is a modern answer to today’s issues, specifically formulated to tackle the unique challenges posed by today’s acidic bio‑fuel blends—issues that legacy competitors fail to address. Its proprietary antioxidants neutralize acidity that otherwise degrades seals, gaskets, filters, and other components, while simultaneously combating water, microbial growth, and oxidation. In short, Star Plus offers comprehensive, targeted protection that preserves system integrity and extends component life in a single, modern solution.

That’s exactly why we’ve developed a line of advanced products for indoor and outside fuel tanks, whether they’re large industrial drums or small residential setups. You’ll find each treatment offers real benefits that help your system continue to work efficiently over the years.

Fuel Ox Star Plus Offers Strong Protection For All Environments

Fuel Ox Star Plus is a versatile heating oil treatment ideal for nearly any fuel oil tank setup. Whether you’re maintaining a tank in the garage or managing an outside fuel tank, this treatment is a reliable way to keep problems at bay. It is designed for all heating oils up to a 5% bio content.

It helps stop the growth of bacteria and prevents the kind of oil sludge that often leads to clogged filters and increased service calls. Star Plus emulsifies water so it doesn’t accumulate in tanks, and conditions the fuel to help maintain filter cleanliness—so your system continues running smoothly.

It also includes the same advanced cold-flo properties and anti-acid protection found in Star Plus Bio, which means it delivers full-spectrum fuel system care even if you’re not using a high bio blend. Just as effective in indoor tanks, it gives year-round performance regardless of outside temperatures.

It’s the only treatment on the market that addresses both gelling and acidity in biofuel heating oil—while also protecting against sludge, water, and wear.

Fuel Ox Star Plus Bio Treats High Biofuel Blends

Fuel Ox Star Plus Bio is specially crafted for storage tanks using biofuel blends of B10 or greater. Since most heating oil now includes bio content—often B5 or higher—it’s important to use a treatment specifically designed for these modern fuel types.

During the heating season, wax and condensation can quickly become a problem, especially when tanks sit outside or stay at low fuel levels. Star Plus Bio includes specialized cold-flo additives to prevent gelling, a major issue with soy-based biofuels that gel at higher temperatures than traditional oil.

This product also helps prevent sludge and algae growth by stabilizing the fuel and protecting the tank from the inside out. With anti-oxidants that combat the natural acidity in biofuels, it helps protect seals and components—eliminating many of the costly maintenance problems associated with bio heating oil.

Many users appreciate how this formula boosts efficiency and lowers the cold filter plugging point, making it the best form of protection during colder months when your delivery schedule might be less frequent. With this cleaner, high-performance option, your system stays reliable every time you fill your oil tank.

Fuel Ox Heat Master Heating Oil Treatment Maintains Indoor Systems

When the heating season stretches on and your fuel levels drop, Fuel Ox Heat Master Heating Oil Treatment steps in to maintain stability and performance. This treatment is well suited for those who want to prevent sludge and condensation while preserving the quality of their fuel.

It works to clean the inside of your tank, so the oil that travels through your system flows freely and with greater power. With water-emulsifying agents and fuel conditioning components, it offers consistent, full-system protection even in indoor environments that don’t face cold extremes.

A good treatment like this goes a long way toward keeping service costs low and efficiency high, even after years of use. If you have an outside tank, Star Plus and Star Plus Bio contain anti-gel features better suited for harsh winter weather.

Heating Oil Sludge Treatment Reduces System Stress

Sludge builds up quietly and slowly, but the damage it does can be extensive. Inside every fuel tank, whether it’s older or brand new, condensation and low quality fuel can lead to a thick layer of oil sludge. That’s why Fuel Ox offers products that target sludge directly.

They work to dissolve and disperse the material, making your system cleaner and more responsive. Emulsifying water, conditioning fuel, and cleaning filters are all part of a consistent treatment routine—the best way to protect your equipment, particularly during those long stretches between service calls or delivery gaps.

The Best Heating Oil Treatment For Cold Weather

In the winter, low temperatures make fuel thick and waxy. If you’re wondering why your system struggles in January or February, the answer might be wax and sludge buildup. Using the best heating oil sludge treatment helps prevent this issue before it begins.

Fuel Ox Star Plus and Star Plus Bio are two of the top products for dealing with this, offering comprehensive protection against both wax gelling and fuel acidity—two of the biggest cold-weather threats in biofuel blends. With cold-flo additives and system conditioners built in, it keeps your fuel tank flowing and responsive when you need it most.
