Archoil AR6500 Diesel Treatment
Archoil AR6500 Diesel Treatment comes in a 40-ounce bottle, treating up to 400 gallons. It is formulated to address issues with modern diesel fuels and aims to restore and maximize performance and fuel economy (MPG). A key feature is cleaning the post-combustion system, including turbo, and the diesel particulate filter (DPF), to help prevent premature failure and reduce regeneration frequency. This product is designed to support injector health and overall fuel system cleanliness, contributing to smoother operation and potentially longer service intervals.
Hot Shot’s Secret Everyday Diesel Treatment (16 oz)
The Hot Shot’s Secret Everyday Diesel Treatment (HSSEDT16ZS) is a 6-in-1 diesel fuel additive designed to treat up to 400 gallons. It includes diesel injector cleaning and fuel system cleaning, with cetane-boosting properties that can enhance power and fuel economy. The formula also helps stabilize fuel and disperse moisture, which can be beneficial in varying climates and storage conditions.
Lucas Oil 10013 Fuel Treatment
Lucas Oil 10013 Fuel Treatment is described as the world’s number-one fuel additive for both gasoline and diesel engines. It provides a broad tune-up in a bottle by treating gasoline and diesel fuels, increasing MPG, and cleaning and lubricating the fuel system, including injectors, carburetors, and the combustion chamber. This multi-use formula is widely recognized for improving overall engine cleanliness and performance.
Power Service Diesel Fuel Supplement Antigel 64 oz
Power Service Diesel Fuel Supplement Antigel 64 oz helps prevent fuel gelling and protects against fuel-filter icing, a common issue in cold weather. It also includes cetane-boosting properties to improve cold starts and overall combustion efficiency. This product is particularly beneficial for diesel engines operating in winter conditions or in regions with fluctuating temperatures.
Hot Shot’s Secret Everyday Diesel Treatment (32 oz)
This 32-ounce version of the EDT delivers a similar 6-in-1 diesel treatment, offering injector cleaning, fuel system cleansing, and cetane boosting benefits. Regular use supports engine cleanliness, improved fuel economy, and better overall performance. The formulation is designed to keep diesel components lubricated and reduce deposits that can hinder efficiency.
Archoil Diesel Fuel System Kit
Note: This kit pairs AR6500 Diesel Treatment with AR6400-D Diesel Fuel System Cleaner. It is designed to restore key fuel system components, including injectors, turbo, and DPF, providing a broader cleaning and protection strategy across the fuel system and helping maintain efficiency and reliability.
Prolube Oil Treatment
Prolube Oil Treatment is an engine oil additive designed to reduce wear, noise, and vibration while boosting fuel economy and horsepower. It is suitable for engines that use both gasoline and diesel fuels and may also offer benefits when used in transmissions and differentials. The product aims to extend engine life by reducing friction and heat buildup.
Buying Guide
- Fuel system goals: If you primarily want injector cleaning and fuel-system lubrication, prioritize additives with strong cleaning and lubricating claims (e.g., EDT varieties, Lucas Oil).
- Cold-weather performance: For regions with cold starts, consider products that explicitly address fuel gelling and anti-icing (Power Service Anti-gel).
- Cetane boost vs. cleaning: Some products emphasize cetane improvements for power and efficiency; others focus on cleaning. In many cases, a combination approach yields the best results.
- Vehicle compatibility: Most diesel additives are widely compatible with common diesel engines, but check your manufacturer’s recommendations, especially if your vehicle uses a diesel particulate filter (DPF) or turbocharger.
- Usage pattern: Regular use (at each fill-up or on a fixed schedule) can maximize benefits. Larger bottles (like 32 oz or 1 gallon) may offer cost savings for frequent users.
- Seasonal considerations: In cold climates, prioritize antigel and cetane-boosting products to ensure reliable starting and smoother operation in winter months.
- Combination products: Some kits bundle a fuel treatment with a system cleaner, providing broader cleaning across injectors, turbo, and DPF. This can be advantageous for high-mileage engines.
Across these products, the common objective is to maintain fuel system cleanliness, optimize combustion, and reduce the risk of costly failures. When choosing a diesel fuel treatment, consider your typical driving conditions, climate, and maintenance history to select a formula that best aligns with your engine’s needs and your long-term maintenance plan.
