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.

      Scott, we’ve completed testing with wet clutch applications and have seen varied results. We continue to pursue and test to see how we can develop the formula to be completely compatible, but at this point in time we do not recommend FR3 for use with wet clutches. Sorry for the inconvenience!

    I bought this FR3 product for the first time a few weeks ago and it seems to be a great product! I have no complaints, so far so good. I don’t mind the price either it seems very reasonable ! Try it!!!! I think it has saved me some gas too. I like to drive like I’m Andretti so I’m not sure……? LOL!!! My engine in my ’95 Pathfinder LE has 151,000 on it now and I just bought it 6 months ago but it does seem to be WAY MORE responsive since I put the FR3 in it just 3 weeks ago. Shoot, just after I put it in it was more responsive!
