Hyundai recommend petrol additive for all fuel injected petrol engine to keep the engine in prime condition. Primarily, it does following three functions.
a. Detergent : It maintains the cleanliness of injector nozzle and other fuel components from carbon and gummy deposit.
b. Dispersion : The dispersing agent completely dissolves small amounts of water in fuel, allowing its passage through filters and preventing it from icing in the fuel lines.
c. Corrosion Inhibitors : Protect injector tips and other fuel systems parts from excessive corrosion.
These are high performance, multi functional fuel additives. These enhance fuel efficiency, gives better ignition quality and better extreme weather operation with much cleaner fuel system.
An oil additive is used to improve the base oil (or oil "base stock") into a better performing lubricant. These are compatible with all type of motor oils.
These are used with transmission oil to increase the oil film thickness. These additives lowers the coefficient of friction which in turn provide following benefits:
It is removing carbon or carbonaceous deposits from engine. It helps in complete combustion of fuel and hence improves the engine efficiency.
