MANNOL Winter Diesel Multifunction 9993 – Winter Diesel Fuel Additive, 450 ml
Comprehensive winter diesel protection – against paraffin crystallisation, fuel system wear and harmful deposits.
MANNOL Winter Diesel Multifunction 9993 is an advanced multifunctional diesel fuel additive (anti-gel) designed to improve cold-temperature fuel performance and support reliable diesel engine operation during severe winter conditions. Its depressant-dispersant technology helps prevent wax crystals from forming larger structures that restrict fuel flow, while additional lubricating and cleaning components help protect the fuel injection system.

- Prevents diesel fuel thickening – helps prevent paraffin crystals from joining together and restricting fuel flow during cold weather.
- Improves low-temperature performance – according to the manufacturer, can reduce the Cold Filter Plugging Point (CFPP) down to −36 °C and the fuel pour point down to −47 °C under suitable conditions.
- Protects fuel filters and fuel lines – reduces the risk of blockage caused by wax crystal deposits.
- Supports reliable cold starts – helps maintain diesel fuel pumpability during winter conditions.
- Additional lubricity protection – helps protect high-pressure fuel pumps, injectors, fuel rails and other important fuel system components against wear.
- Fuel injector cleaning – detergent-dispersant components help remove and prevent deposits, carbon build-up and varnish contamination.
- Improved combustion performance – helps maintain an effective injection spray pattern, reduce exhaust smoke and stabilise engine idling.
- Condensation protection – the manufacturer states that the additive helps neutralise water condensation and reduce the risk of ice blockages in the fuel system.
- Wide diesel engine compatibility – suitable for naturally aspirated and turbocharged diesel engines, including vehicles equipped with DPF and catalytic converters.

- Shake the bottle thoroughly before use.
- Ensure the additive is liquid and the diesel fuel has not already thickened or gelled.
- Add the calculated amount directly to the fuel tank before refuelling or immediately afterwards.
- Maintain the recommended mixing ratio of 1:500. The product is self-mixing.
- Use regularly during the colder months, starting in autumn, to help maintain winter protection.
Important Winter Usage Information!The additive must be mixed with diesel fuel before the fuel has frozen or lost its fluidity. If the additive has solidified due to cold temperatures, allow it to warm to room temperature before use. Only add the product in liquid form. This anti-gel is not intended to thaw already gelled diesel fuel.
Applications and Compatibility
Suitable for passenger cars, commercial vehicles and other diesel-powered vehicles. Compatible with modern Common Rail injection systems, naturally aspirated and turbocharged diesel engines, including vehicles equipped with diesel particulate filters (DPF) and catalytic converters.
Designed for conventional summer and winter diesel fuel. Not intended for heating oil, marine fuel or unsuitable diesel fuel substitutes.
Frequently Asked Questions
How much additive is required for 50 litres of diesel?
At a 1:500 ratio, 50 litres of diesel fuel require 100 ml of MANNOL Winter Diesel Multifunction.
Is the additive suitable for Common Rail engines and DPF systems?
Yes. The manufacturer specifies compatibility with modern diesel injection systems and diesel engines equipped with DPF.
Will this additive help if the diesel fuel has already frozen?
No. It is designed for preventive use before diesel fuel loses its fluidity.
* Please note: The manufacturer's figures (CFPP down to −36 °C and fuel pour point down to −47 °C) are achievable performance values, not guaranteed results for every fuel. Actual performance depends on the initial fuel quality, characteristics and operating conditions. Follow the recommended dosage and instructions on the product label. -
