* Product Material : The chemical of a volatile substance and the vegetable carbon fiber and the mineral resin be mixed. * Object : Diesel/Gasoline/LPG Engines for the vehicles, trains, ships, heavy equipments, and others. * One Set : One Bottle of Cleaner and One Bottle of Engine Metal(Cylinder) Surface Treatment. * Features : (1) It is restoring the engine to the best condition, and it provides the various economical benefits such as the fuel economy, reduction of the exhaust fumes, reduction of the engine oil exchange period and etc. Once you put it into the engine, you can expect the excellent effect of the improvement and performance of the engine. (2) Even though you change the engine oil, it is getting better without losing its ingredients. And, improved performance will be maintained with long-lasting. Also, the vegetable carbon fiber and the micro resin reduce abrasion of the engine metal by 2~3 times, and it allows you to be given a smooth driving by extending the engine life to the max. (3) Even use once, the effect is maintaining for long time, but if you put the Engine Cure one more time after you drive 50,000~80,000km, the performance will improve even better and will last for a long time. (4) If you think that the effect is not satisfied, replace the engine oil as you usually did after drive at about 5000km. Then you can expect a good effect by removing the impuritys as like the carbon, sludge and etc. and also by the technical principle. After that, you can change the engine oil around 15,000km regularly. (5) If the gasoline engine and LPG engine are driving a long distance, it will show very good effect by injection of the metal treatment after used the cleaner as the diesel engine. It is not an oil type, it is a volatility type. So, there is no need to worry about clogging the piston ring holes. (6) Also, the resin, among the Engine Cure, which be mixed with the chemical of a volatile substance, the vegetable carbon fiber and the mineral resin, be only adsorbed onto the metal surface. The liquid only does its own function (the catalyst what helps the cleaning and absorption), and it will disappear quickly. Micro resin, which be adsorbed onto the metal surface, is composed of the smooth materials, which is smooth than the material surface, and it reduces the friction force. If you use the engine cure to a new car after drive around 20,000~30,000 km, it will even help to maintain the good condition of new car. * 480ml/1 bottle. * 2 bottles/1 set. * Size: 12.5cm x 6.5cm x 22cm.
