Additives

Additives are ingredients that are added to the fuel or oil to improve their properties. Additives improve engine performance, reduce fuel consumption, and extend the service life of engine parts.

Continue

Types of additives

Fuel additives

Prevent the engine from getting clogged up with carbon impurities from the fuel and reduce engine knocking. Keep the injectors clean and reduce fuel consumption, improve performance, increase acceleration, and prolong the engine lifespan. Make starting a car in cold winter weather easier, reduce emissions, and protect the fuel system from corrosion. The dosage is always listed on the packaging; the usual ratio is about 1:1000.

Oil additives

Reduce wear and tear inflicted on the engine and transmission and keep them in a good shape. Also reduce the car’s oil consumption (and the amount of exhaust smoke) and engine noise. The additive should be added during every oil change to make sure it removes unwanted residue.

GOLD EAGLE Engine wash 887 ml
Engine Cleaner - volume 887 ml, Professional additive for thorough cleaning of the combustion engine from deposits and impurities formed by normal use of engine oil. It can loosen seized piston rings and clogged channels. It keeps the crankcase perfectly clean and thus promotes proper circulation and full oil change. With regular use, it will significantly extend the life of the engine. It can be added to mineral and synthetic oils in both diesel and gasoline engines. When cleaning old, neglected engines, there is a risk of undesirable backlash due to the release of large carbon and dirt deposits. Use: Warm up the engine to operating temperature before changing the oil. Switch off the engine and add the contents of the bottle to the old oil through the filling opening. Then start the engine and let it idle for 5 minutes. Replace old, dirty oil and oil filter with new ones. The contents of the bottle are sufficient to clean the engine of a normal passenger car (4-6 litres of oil).

EUROL Petrol System Cleaner 250 ml
Engine Cleaner - volume 250 ml, Additive designed for quick cleaning of the entire petrol fuel system. It is recommended for use if you find that the quality of the gasoline is inferior and the engine suffers from a loss of performance or if using gasoline with ethanol as a bio-ingredient (E10). These fuels can cause carbon deposits, inefficient fuel ignition and reduced engine performance. In particular, modern small engines with high power output are very sensitive to deposits that form in the combustion chamber and fuel system. This product can also be used when poor quality fuel has been used for a period of time in order to eliminate problems that have accumulated during that time. For best results, use two tanks consecutively or every 2,500 km. In case of urban traffic, it is recommended to shorten the interval. We recommend using a 250 ml bottle of Eurol Petrol System Cleaner in 35 to 65 L of fuel before refuelling.
