Additive "SDA" is designed to restore and maintain the performance of diesel fuel systems, including Common Rail systems and "pump-injector". Additive cleans, lubricates, protects injector and fuel pumps from corrosion, maintaining their good condition. Restores cetane number of fuel to optimal values.

Effects after application
Additive for diesel fuel "SDA" (stands for Suprotec Diesel Additive, pronounced "SDA") is a means of permanent use and is recommended to be added to the fuel at every refueling of the car. The main function is the cleaning and prevention of pollution of fuel equipment, the extension of its life. The composition of the additive provides a number of actions in the fuel equipment:

Cleaning up Softly acting surfactants in the composition of "SDA" gradually and safely remove lacquer deposits in the nozzles and high-pressure fuel pumps, prevent new contaminants. This ensures the long-term effect of maintaining the working capacity of the fuel channels inside the pumps and injectors, ensuring the correct fit of the mechanical parts: pump plungers, needles of the injectors and others.
Lubrication. The lubricating components of the additive reduce wear in the friction units of the fuel equipment, which helps to maintain the nominal operating pressure of the fuel in the system, extends the life of the units within the factory specifications.
Corrosion protection. The corrosion inhibitor blocks the access of water molecules contained in the fuel and condensate to the metal surfaces of the parts, which protects the fuel system from corrosion and wear.
Restoration of worn surfaces. Additive for SDA diesel fuel uses the “Suprotec” tribotechnology, which restores friction surfaces in fuel equipment (on plungers, nozzle needles, valves), which ensures the proper operation of the units.
Correction of cetane number.
In a complex, the effects carried out by the additive improve the quality of sprayed fuel, the formation of the correct fuel plume. This leads to the following effects:

fuel economy;
maintaining engine power and throttle response;
facilitating engine start, especially at low ambient temperatures.
extending the service life of the fuel equipment, including reducing the likelihood of engine failure as a result of a leak in the needle / nozzle assembly of the fuel injectors and fuel accumulation in the cylinders during a long vehicle downtime;
prolongation of the service life of turbochargers (high-quality combustion of the fuel ensures that less soot and other contaminants enter the turbine);
extending the service life of the engine's environmental system, in particular particulate filters .;
reducing exhaust opacity and harmful impurities;
The cleaning additive for the SDA diesel engine is specially balanced for permanent use. It is safe for fuel filters, including those inside the injectors, as it removes dirt gradually.

"SDA" does not change the temperature properties of diesel fuel, does not reduce the effectiveness of anti-gel additives.


Instructions for use
1 bottle of 50 ml is designed for 40 - 60 liters of fuel (approximately 1 ml per 1 liter of fuel). Before refueling the vehicle, pour the additive into the fuel tank.

For this:

shake the bottle thoroughly;
open the bottle and pour the additive into the fuel tank (if necessary, use the fuel funnel);
refuel the car.
If the vehicle has traveled more than 50,000 kilometers, it is recommended to fill 2 bottles at the first two refueling stations.
50 ml for 40 - 60 liters of fuel (or at the rate of 2 ml per 1 liter of fuel).
