graphene engine additive is excellent stuff.Benefits are as follows: 1. Improve the fuel efficiency (5-20%) 2. Enhance the power output(5-10%) 3.Reduce friction, abrasion and wear of engine and prolong the engine service life 4.Reduce the emission(20-30%)，Remove the carbon deposit and black smoke 5.Reduce the noises（9.6%） and vibration（12.6%） 6.Accerate the heat dissipation
