The Science

Hot Shot’s Secret FR3 is a lubricity enhancing oil additive that increases the lubricating & wear reduction properties of the host oil. The product contains patented synthetic lubricants that have unique lubricating properties even compared to PAO or mPAO synthetics of the same viscosity. The anti-wear component of the formula is a patented carbon nano particle that fills in microscopic irregularities on the machined surface to provide a smoother surface for the lubricating film to form. The synergy of these components extends the base oil performance in shear stability, oxidation stability, film strength & especially friction reduction.

Benefits

Heat and friction silently steal power from your engine. The scientists from LSI Institute have uncovered a powerful lubricity agent…Hot Shot’s Secret FR3. One treatment of FR3 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

  • 5 quart (car): 8 ounces FR3
  • 15 quarts (truck): 23 ounces FR3
  • 45 quarts (semi): 64 ounces FR3

Add To:

  • Engine oil
  • Power steering
  • Hydraulic system
  • Differentials

Recommended Frequency:
Use one treatment of FR3 every oil change.

Use in All Engines:
Semi-trucks, pick-up trucks, farm equipment & autos. Effective in all engines including: Ford Powerstroke, Dodge Cummins, GM Duramax, Saab, Volkswagen, Audi. You can use FR3 to treat any oil-lubricated system except air conditioning and aircraft. Even though FR3 is an industrial product, you’ll find that small two cycle engines love it; just add FR3 to your oil before mixing it with the fuel. Your automobile, light truck or other personal vehicles will benefit from FR3 in the engine, power steering unit, and differential.

    My name is Jonathan. I own a Ford F550 a 2005 model year with 6 liter Power Stroke diesel. It’s been modified so it carries about 15 to 17,000 pounds daily. I discovered Hot Shot’s Secret by following an online forum and I can’t be happier as a user of Hot Shot’s Secret! I’ve noticed cooler operating temperatures, primarily that the engine runs so smooth and so quiet. I know that the Hot Shot’s Secret is definitely helping me out! My fuel economy is outstanding. I’m getting on average between 12-13 miles per gallon. I’m also using the [Friction Reducer] and the [Diesel Extreme] for the fuel, trying to treat every aspect of the engine. The customer support is outstanding! I’m getting preventative treatment, rather than reactive treatment. Hot Shot’s Secret, that’s the way to go!

      I have a 2014 BMW X3 M-Sport. Can I use in that engine? Also, do I need to substitute or in addition to the oil?
