C51 – Premium Red Diesel
C51: the premium red diesel blend built for your farm
Running a farm is no small feat, and having a fuel you can trust is essential. C51, a premium blend of red diesel (gas oil) and two additives, is purpose-built to handle the demands of rural life. Designed to tackle two of the most common issues farmers face when using standard red diesel, C51 improves efficiency and shelf-life.
Many tractors and farm machinery are designed to run on high-spec road diesel (DERV). However, lots of UK farms rely on red diesel, which has a lower specification and can lead to reduced efficiency. Since 2011 red diesel has included increased biodiesel content which — while better for the environment — can lead to issues including diesel bugs or tank sludge in stored fuel, which can block fuel filters.

C51 solves these problems with two powerful additives:
- Gas oil extra: This upgrade improves red diesel’s performance, making it suitable for modern engines calibrated for road diesel. The benefits include easier starting, better pulling power, smoother performance, improved combustion, and reduced smoke.
- Anti-bug: This additive prevents diesel bug contamination, ensuring your tank stays clean and your fuel filters are clog-free.
