Hot Shot’s Secret FR3 Friction Reducer is a one-of-a-kind, 100% synthetic oil additive that improves performance and protects engines. It is blended with three patented lubricants, including a nano lubricant, and is proven to reduce engine wear by up to 43% plus improve your vehicle’s performance by increasing horsepower and fuel economy up to 5% each.

FR3 Friction Reducer will improve your vehicles oil by improving its shear and oxidation stability, film strength and especially friction reduction. This means your oil will stay in specification longer, stay cleaner and protect your engine better, allowing it to last longer.

FR3 Friction Reducer is recommended for any vehicle or equipment and works in conventional and synthetic oil. It can also be added to power-steering pumps, differentials and hydraulic systems.

  • 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.

NOTE: FR3 displaces the same amount of oil. Example: If your oil capacity is 10 quarts, 15 oz. of FR3 and 9 quarts + 17 oz. of oil. Do not use in conjunction with other aftermarket oil additives, including Stiction Eliminator

There is not a product in the world that contains the same chemical makeup as Hot Shot’s Secret FR3 Friction Reducer, making it truly a one-of-a-kind. It contains the most effective nano lubricant available, nano carbons. Nano carbon particles are spherical in shape and are less than 10 nano meters in diameter. This allows the lubricant to find the voids and blemishes on a machined surface, fill these gaps and provide a smoother surface for the lubricating film to form.

While nano carbons are highly effective on their own as a friction reducer, FR3 Friction Reducer also contains two other patented lubricants blended into the formula. The synergy between these patented lubricants have unique lubricating properties even compared to PAO or mPAO synthetics of the same viscosity. FR3 Friction Reducer is also negatively charged, allowing it to attach itself to the oil-wetted components inside your engine. The esters inside FR3 Friction Reducer are also responsible for the increased rubber seal lubrication as well as a slight swelling of seals for less oil leaks.

Wear rates are reduced by 43% on the ASTM G-133 test when using FR3 Friction Reducer. The patented nano particles cross link at the surface, which increases film strength and boundary lubrication. The synergy of these components extends the base oil performance in shear stability, oxidation stability, film strength and especially friction reduction.

Lost compression is restored by cleaning deposits on the rings and pistons and by providing a smoother sealing surface for the rings, which results in better ring sealing, less blow-by and increased combustion efficiency. The reduction in the coefficient of friction reduces operating temperatures and improves the oxidative stability of the host oil ensuring longer life for your engine. Fuel mileage and horsepower gains of 5% are not uncommon with the use of FR3 Friction Reducer, as backed by dyno and road testing.



No other diesel oil or fuel additive has a better guarantee than Hot Shot’s Secret products. If our products do not deliver as promised, then we will give you your money back. End of story.

    5 out of 5 Great for Zero turn Hydraulic systems

    Adam J Jagneaux (verified owner)

    I run quite a few Zero turn mowers all day cutting grass and I started using FR3 in our systems as an added measure of protection. Most notable observation was how it quieted down the hydraulic motors after hours of use, additionally it must be running cooler because the cooling fans in the hydraulic fluid system do not kick on nearly as often as the normally do. As to what it is contributing for long-term reliability in our units only time will tell. I definitely feel better knowing it’s in there and will continue to use. I previously used friction reducer in these units with great results so it wasn’t a question to try a new and improved product. Keep up the great work! Love you products

    Recently added one 8-ounce bottle to the crankcase of my Ford Fiesta. Was getting 33.6 miles per gallon before adding it and immediately after adding it I was getting 40 miles per gallon plus. Two weeks later I am getting 42 to 44 miles per gallon depending on my driving driving.

    simply amazing

    5 out of 5 Smooth quiet ride

    Keith Ferguson

    I started out using stiction eliminator and diesel extreme for some issues I was having running a little rough at idle and not quite as responsive as I would like under acceleration on my 2000 7.3. After running stiction eliminator and diesel extreme, the issues have disappeared, running smooth at idle and acceleration has been consistent. The next oil change I tried FR3 and with 248,000 miles so far, my truck runs like it was new again, idle is not only smooth but seems to be a little quieter, even my wife has noticed a difference at highway speeds at how quiet it is. No need to spend $50,000 on a new truck when you have products like these to keep an old truck running. Thanks
