exocet® Gas Oil Supreme
£29.95
- Improves combustion efficiency for easier starting, greater pulling power and smoother power delivery
- Protects against premature wear in fuel pumps and fuel injectors, and reduces friction
- Prevents emulsions forming and resultant filter blockages
- Increases fuel-water separation
- Aligns with modern engine calibrations
exocet® Gas Oil Supreme is an oil additive for diesel engines. This advanced fuel additive is designed to benefit both mineral diesel and biodiesel blends.
It is beneficial to use when: a vehicle lacks power, misfires or ‘runs rough’; an engine manufacturer recommends the use of a fuel additive; excessive smoke is observed; the FAME content of the fuel is known to have increased; fuel is being used in a tier III or later vehicle (typically post 2005).
This fuel enhancer is formulated to allow modern diesel engines calibrated on EN590 DERV to run on red diesel. It prevents deposit formation throughout the fuel delivery system, especially in the injectors and fuel pump. This avoids fuel consumption increases by keeping the system clean and running at optimum performance.
The oil additive for diesel engines will enhance the performance of older vehicles. It counters any negative effects resulting from the introduction of the latest gas oil specifications, notably the reduction in sulphur content and the increase in the allowable FAME (biodiesel) content. exocet® Gas Oil Supreme compensates for some of the deleterious effects of a higher FAME content, such as reducing water pick-up.

Frequently Asked Questions
Red diesel fuel contains various additives that can vary depending on the specific formulation used by manufacturers. Common additives found in red diesel fuel include:
While it’s generally recommended to use additives from the same brand for optimal compatibility and effectiveness, mixing different brands of red diesel additives may not always cause harm. However, following the manufacturer’s recommendations and consulting with a professional if unsure is advisable for best results.
The frequency of adding red diesel additives depends on factors such as fuel quality, engine condition, and usage patterns. As a rule of thumb, adding red diesel additives with each tank refill helps maintain fuel quality, prevent injector deposits, and ensure optimal engine performance.
Red diesel, due to its higher sulphur content compared to regular diesel, can potentially accelerate Diesel Particulate Filter (DPF) clogging in vehicles equipped with DPF systems. Using red diesel additives formulated to reduce sulphur content and maintain DPF cleanliness can help mitigate these issues.
While not essential, red diesel fuel additives offer numerous benefits, including improved fuel efficiency, engine performance, and protection against injector deposits and fuel degradation. Whether additives are necessary depends on individual circumstances and preferences.
The higher sulphur content in red diesel can contribute to increased injector deposits over time, potentially affecting engine performance and fuel efficiency. Regular maintenance and the use of quality red diesel additives formulated to clean and protect injectors can help minimise these effects.
