The Science

LSI’s NanoSyn 251 is an engine and oil additive that is engineered with patented Nano Carbon Technology to greatly reduce friction and wear while also improving performance. NanoSyn 251 adheres to metal surfaces, filling in microscopic irregularities to provide a smoother surface for the lubricating film to form. This extends the base oil performance in oxidation stability, film strength and especially friction reduction. NanoSyn 251 is proven to extend engine life, increase fuel economy and horsepower and allows for longer oil change intervals.


Heat and friction silently steal power from your engine. The scientists from LSI Institute have uncovered a powerful lubricity agent…NanoSyn 251. One treatment of NanoSyn 251 to your oil and your diesel will run cooler and have increased towing power. Negatively charged synthetic ester tenaciously attaches to all internal parts completely lubricating your engine.

Treatment Ratio

  • Use approximately 1.3 OZ per 1 QT of oil.

Add To:

  • Engine oil
  • Power steering
  • Hydraulic system
  • Differentials
