As you prepare to store your tractors and combines for the season, remember that most major engine manufacturers recommend filling the fuel tank completely. This practice reduces condensation in the tanks and helps eliminate moisture-related issues when you start up in the spring. For combines that may not be used until the following fall, proper storage is even more critical.

Using a high-quality diesel additive like Dieselex Gold is essential for both fuel system protection and performance during engine operation. Dieselex Gold contains eight components designed to mitigate fuel-related startup issues that can occur after months of storage, while also protecting the fuel system during use.

Key Benefits of Dieselex Gold:

1. Fuel Stabilizer: Dieselex Gold includes a fuel stabilizer that provides thermal stability during engine operation. With new fuel injector pump technologies, up to 50% of the fuel can recirculate through the fuel rail, heating it to temperatures exceeding 65°C. This can lead to accelerated oxidation, creating gum and deposits that clog fuel lines and filters.
2. Moisture Control Chemistry: This unique chemistry helps dry out tanks by allowing the fuel to carry additional dissolved moisture through combustion, preventing gum and deposit formation for extended fuel storage life.
3. Lubricity Enhancers: These additives extend the life of pumps and injectors. While most diesel fuels meet the ASTM D975 standard, the Engine Manufacturers Association (EMA) recommends higher lubricity levels. Dieselex Gold consistently outperforms these recommendations, providing superior protection.
4. Corrosion Inhibitors: Protecting metal components from rust and corrosion is vital, as degraded metal can block filters and injectors. The corrosion inhibitors in Dieselex Gold pass both ASTM-D130 and Cummins N14 injector corrosion tests, ensuring your system stays clean and efficient.
5. Detergency Additives: These ingredients keep injectors clean, restoring power and improving fuel efficiency. Research shows that deposits can form in injectors within 20-40 hours of operation. Dieselex Gold's robust detergency chemistry has earned a “superior” rating on the industry-standard “Cummins L10 Injector Depositing Test.”
6. Cetane Improvers: Higher cetane numbers help engines start faster with less chattering, knocking, and smoke. Typical diesel fuel has a cetane rating of 42 to 45, while Dieselex Gold boasts a cetane rating of 46 to 49.

Dieselex Gold is easy to use—it is blended as it is loaded onto the delivery truck or directly into the line as the fuel is delivered.  This eliminates the need for measuring and pouring additives separately, making it a hassle-free solution for diesel engine care.
