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.

    I ride a BMW k1600gt motorcycle, and the engine and the transmission share the oil. Can I use fr3 under these conditions ?

      Hello Mark,
      At this time we do not develop products that are compatible with wet clutches commonly found in oil systems like the one you described. FR3 can be used in motorcycle engines when they are separate from the primary/wet clutch or transmission, but we do not recommend it in systems like yours. In-house testing on wet clutches has had varied results, both favorable and unfavorable; but at this time cannot recommend it for your motorcycle.
      Thanks for your inquiry!

    I tried this product in my 2009 Honda Civic (155,000 miles). I was about 2,000 from my next scheduled oil change. The treatment only called for 8oz so i was able to just add it to my oil without draining anything. I instantly began to notice an increase in my fuel economy! I was averaging about 23 mpg before and now im up to about 27 mpg. I will definitely be using this product again after my next oil change! Hopefully my fuel economy will improve even more.

      Can this product also be used at the same time as the Stiction Eliminator, or should I run it in a future oil change?

      Hello Allen,
      We highly recommend using FR3 and Stiction Eliminator separately, as explained below, thanks!

      Can fr3 be used in a new motor or wait for a break in period before use

      If you’re using an oil specific for breaking in an engine, I would recommend using that break-in oil by itself, and then adding FR3 when you switch to your choice of engine oil. FR3 can definitely be used in a new engine. While the restorative capabilities of the FR3 won’t be as noticeable as an engine with 100K miles, you’ll be better off with the reduction of friction and fortified engine oil from the start!

      FR3 can be added before initial start up if you’re using engine oil or after the break in-period if you’re using a break-in fluid or oil. If you’re planning to use regular engine oil, for cost effectiveness I’d recommend a half dose for the initial start up interval, then a half dose every oil change until you are ready to run a full length oil change interval and at that point you can use FR3 as the label recommends. Thanks!
