Haris Sensor Technologies Pvt. Ltd. Supplies Top Fuel Lube Oil Additive. Haris Sensor Technologies Pvt. Ltd. Manufactures force, pressure, flow and digital indicators. The Top Fuel Lube Oil Additive is an anti-wear agent, made of Nanometer-level inert granules and supplementary materials. It is an engine protection reagent and also used for the situation where lubricant is needed. Top Fuel Lube Oil Additive is 100% safe and eliminates knocking. When this Lube Oil Additive is added into the lubricant, the inert particles soon spread evenly in the lubricant. It can minimize the frictional resistance and reduces wear & tear, extends the taxiing range [idle running time], increases the power of engine, reduces the engine noise, life span of lube oil is doubled and reduces the fuel consumption at high speeds by big margin.
