Engine Armour Tech -

Features

Engine Armour Tech is a SAE J1321 tested penetrating ceramic liquid metal sealing formula that has been well proven to reduce engine wear in tests by multiple independent laboratories and 10 years of successful track record in Canada and 12+ countries.  It clears away soot & carbon deposits and fuses into microscopic pores in meta as well as prevents the formation of sludge & abrasive carbon. Lubricants treat symptoms - We ATTACK the cause of soot & carbon damage.
It has been proven to SIGNIFICANTLY reduce soot build-up in DPF, turbo chargers and EGR valves as well as enhance engine performance - by promoting a more complete burn - thereby increasing torque, horsepower - reduced fuel consumption & emissions. We are not an oil additive but rather an inert liquid that WILL NOT mix with oil or change oil viscosity.  The effects of treatments extend PAST oil changes and can last as long as a year - depending on time and intensity of engine use.
