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.

    5 out of 5 FR3 in Motorcycle Wet Clutch Applications

    Jim

    I used the older FR3 formulation in my 2011 Victory motorcycle with no noticeable issues at a 1.5 oz/qt ratio. You have since stated it is not for use in wet clutch applications on the newest formulation. However, I have been using the newest formulation for several years in two other wet clutch motorcycles at a dosage of 1oz per/qt with no noticeable issues. Do you think I am getting any benefit from using the lower dosage or am I just wasting money? I have been using your Stiction Elimination and FR3 products as recommended per label instructions since 2015 in multiple vehicles and am completely satisfied. Thank you for making such superior and affordable products for us enthusiasts.

      We do not recommend the FR3 for wet clutch applications simply because we do not have enough test data and want to be sure our customers have no issues. We’ve tested the FR3 in automotive automatic transmissions and limited slip differentials which we also did not recommend and the FR3 is now part of the formulas for our fluids in those applications. All of our testing on the motorcycle wet clutch systems has been successful and we don’t foresee any issues, but we just don’t have enough data to endorse it’s use in that application. Thank you for being a loyal customer, Jim!

    Does FR3 work well?

    William (verified owner)

    Some family members and our plumber tried out the FR3 and told me they immediately felt a difference in how their cars and trucks run. One person has a mileage indicator which read plus 2 miles per gallon. I personally use the FR3 in my engines and power steering.
