Has kept fuel clean and prevented issues for years, proving its reliability.

The Power Service 09280-06 Clear-Diesel Fuel & Tank Cleaner is designed to enhance the performance of diesel engines by effectively removing water and contaminants from fuel tanks. One of its key strengths is its compatibility with all types of diesel fuels, including Ultra Low Sulfur Diesel and biodiesel blends, making it versatile for various users. Its water removal efficiency is notable, as it helps prevent fuel-filter plugging and protects against corrosion, which can save users from potential costly repairs down the line.

Another advantage is the inclusion of the Petro Fresh additive, which ensures long-term fuel stability, a great feature for those who store diesel fuel for extended periods. Additionally, it can be used alongside Bio Kleene Diesel Fuel Biocide to address microbial contamination, making it a comprehensive solution for maintaining fuel quality.

There are a few considerations to keep in mind. While the product is easy to use, some users might find the required frequency of use to maintain optimal performance slightly demanding, especially if they’re not familiar with regular maintenance of their diesel engines. Additionally, it may not work as effectively in extreme conditions or heavy contamination scenarios without proper follow-up treatments. For diesel vehicle owners, especially those who often deal with fuel storage or live in areas prone to water contamination, this product can be quite beneficial. It stands out for its effective performance, ease of use, and ability to work with various fuel types. However, as with any additive, results may vary depending on the specific conditions of the fuel system it is applied to.

Buying Guide for the Best Fuel Tank Water Remover

Choosing the right fuel tank water remover is essential for maintaining the efficiency and longevity of your vehicle's engine. Water in the fuel tank can cause a range of issues, from poor engine performance to corrosion and damage. To select the best product for your needs, it's important to understand the key specifications and how they impact performance. Here are the main factors to consider when choosing a fuel tank water remover.
CompatibilityCompatibility refers to whether the water remover is suitable for the type of fuel your vehicle uses, such as gasoline or diesel. This is important because using an incompatible product can lead to ineffective water removal or even damage to your engine. To navigate this, check the product label to ensure it matches your fuel type. If you have a gasoline engine, choose a remover designed for gasoline; if you have a diesel engine, select one formulated for diesel.
Water Removal EfficiencyWater removal efficiency indicates how effectively the product can eliminate water from your fuel tank. This is crucial because higher efficiency means better protection for your engine. Products are often rated by their ability to remove a certain percentage of water. Look for products that claim to remove at least 90% of water for optimal performance. If you live in a humid area or frequently experience condensation issues, prioritize higher efficiency removers.
Additive BenefitsSome water removers come with additional additives that can clean the fuel system, improve fuel stability, or enhance engine performance. These benefits are important as they can provide extra protection and maintenance for your vehicle. When choosing a product, consider if you need these additional benefits. If your vehicle is older or you want to maintain peak performance, opt for a remover with extra additives.
Ease of UseEase of use refers to how simple it is to apply the water remover to your fuel tank. This is important because a product that is difficult to use may lead to improper application and less effective results. Products typically come in liquid form and are added directly to the fuel tank. Look for products with clear instructions and convenient packaging, such as a bottle with a built-in measuring cap. If you are not very experienced with vehicle maintenance, choose a product that emphasizes ease of use.
Frequency of UseFrequency of use indicates how often you need to add the water remover to your fuel tank. This is important for maintaining consistent protection against water contamination. Some products are designed for one-time use, while others may need to be added regularly, such as with every fill-up. Consider your driving habits and how often you refuel. If you drive frequently or have a large fuel tank, a product that requires less frequent use may be more convenient.
