SKU: FR3 Category:

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 have always received good results with Stiction Eliminator. Now LSI has FR-3 which I use when my engines are clean. On my engines which have a bypass filter, I use FR-3 all the time. A day before changing the bypass filter, I add some Stiction Eliminator.

    I have seen a positive impact on my mileage since I added FR3 to my Impala’s engine oil. On a recent trip I was getting 30 mpg at 80 mph on a level highway. Speeds down to about 50 mph got higher mpg up to around 40. I bought 2 more gallons to share with friends.

    Larry250DTR (verified owner)

    1st I used in a Nissan Titan with tapping sound coming from valve covers. Using name brand synthetic and even tried the old Marvel stuff, and still tapping. I added 1-2 ounces or so, as not to overfill, and tapping gone. I’ve since put some in my Expedition, tractor & rotary cutter gearbox, and 2-cycle gas. Next will be to video my tapping jeep motor before & after.

    5 out of 5 More of a question than a review

    gilzapanta

    In some previous questions on other reviews for Hot Shot’s Secrets, I asked if mixing the Stiction Eliminator with the FR3 is okay, response was not recommended. I’m alright with that and have followed those directions. My question is can you use FR3 and TBN together? I have used TBN with the Stiction and have been very pleased with it, but should have asked if this is okay as well?

    5 out of 5 2009 Chevrolet duramax oil pressure drop

    ron johnson

    Hello, first off I love the hot shot secret products I have been using. I upgraded from a 2004 duramax to a 2009 duramax recently and started using fr3 for the first time. I did see an awesome increase immediately, both under towing and non towing highway driving. I also noticed my idle oil pressure went down to 16-17 lbs under idle from 21lbs, and saw an under load pressure at 1600 rpm of 25-30 lbs. I still this normal due to the lack of friction within the motor now. Thank you.

    HOW TO USE PROPERLY

    justin

    When using your product what is the right way? For example, if my trucks takes 12 quarts of oil to be full do i put all 12 quarts of only oil in engine and then add your product on top? Or without getting exact would i only put 10 quarts of oil in truck and put 2 quarts of product in giving me a total of 12 fluid quarts but not a full 12 of oil. If you can help i would appreciate it.

      Hi Justin, good question! To be specific, 18 OZ of FR3 is perfect for a 12 quart system. You can keep it simple by using 16 OZ/ half a quart of FR3, REPLACING engine oil.

      So 11.5 quarts of oil and adding half a quart on top (to not overfill)…thanks!

    2008 Ford Escape with 143,000 miles on it. I used the FR3 product three weeks ago. Within the first week I could notice the difference. My engine is idling smoother and acceleration is back to what it was like 100K miles ago! I am going to be ordering more of the product and l am looking at some of the other Hot Shot products as well!

    Chad Six

    I was looking to switch over to the Blue Diamond oil (15w40) but wanted to add the FR# in the mean time. Is it too soon at 16k miles to use the FR3? if so how long should I wait? Also is it too soon to start using the full syn diamond oil too?

      Hi Chad, that is great timing, after 15k miles or so, to start protecting your engine. As long as you’re a few oil changes past the break-in period for both FR3 Friction Reducer AND Blue Diamond infused with FR3. Thanks!

    I didn’t follow the instructions exactly. The oil change was done about 700 miles by the time I received the FR3.
    I put it in and noticed the difference in quietness of my 2017 car. My next oil change I will be putting in another.

      The FR3 is NOT a recommended zinc substitute. However, in our testing with high zinc racing oil, it does help supplement and gives up to a 5% horsepower increase!

    Used the FR3 in both My Kid’s Jeep wranglers, A 1998 & a 2000, Both have the 4.0 motor, As with all 4.0 motors You get the lifter noise that is annoying. After putting in the FR3 in after 2 oil changes both jeep’s have no more lifter noise. And they both run a lot smoother then when We first got them. I put it in the Oil, P/S fluid and the Differentials.

      Hi Frank! For new or low mileage vehicles we actually recommend waiting until 40-50k miles before a need for Stiction Eliminator. Using FR3 around 15k miles, or at least after the break-in period, will help extend the engine life and keep things clean and lubricated…thanks!

    Started using Hot Shot Proucts for about the last 12,000 miles. So far it seems to be doing a great job. The one thing that I have noticed the most is the engine temp. I pulled a 3 Horse Trl. It was loaded to the max. The temp would get up to 209-212 before using hotshot product. But on that long haul with a heavy loaded trl it never got over 200 degrees. So I would have to give it a 5 star. I’m now using All hotshot products.

    I run FR3 in everything and have noticed the vibration on the mower and one of my old cars has decreased a little. It does seem to help according to the oil analysis I send in to a separate company. I run diesels for 2 of my vehicles so I get oil samples run to make sure I don’t have diesel fuel in the oil (bad injectors) and was kinda shocked when they told me the metal content had dropped, which is good (less engine wear). I’ll continue running this product.

    Added this to my 6.0, engine is way quieter now. Cruising at 65 I can’t hear the diesel clatter anymore, just the hum of my mud tires and the whistle of my turbo!

    Since it was was my first use, I haven’t had enough time to assess the product. I fully expect it to work as advertised, though I suspect it will be a while since I already use full synthetic oil and get better than EPA estimates for fuel economy for my 2008 Avenger with 2.7 liter V6.

      Hi Lane, with 7 quart capacity, it is still recommended to use 8 oz of FR3…replacing 8 oz of oil. Good to hear you’re using synthetic!

      Hi Gelasio, that is a good mileage-marker to start with the Stiction Eliminator, with a maintenance dosage every 3-4 oil changes. FR3 is added during the in-between oil changes, thanks!

    added fr3 in my 98 expedition with 300k miles. it had had a rough idle even after a tune up and saw this on the shelf at my local rural king. I saw a video of a different nano product added to a running freightliner so I tried it to the old ford. within 8 seconds the idle had calmed and you could tell how much smoother the ride was and the throttle response seemed to pick-up slightly as well. very impressed

      No it will not, Mike good question. It filters down to 2 microns to remove any wear metals in the oil. 2 microns equals 2,000 nanoparticles of FR3, for reference…hope that helps!

The diesel increased 20% more miles per tank on fuel, runs smoother and the gas Cherokee increased 10-15% more also. They both run cooler, smoother and cleaner.

    I put in archoil 9100 at my first oil change on my 2017 silverado 6.6 duramax l5p and it seemed to make a mileage difference of 1-2 ish. I used rotella t6 with it. With my second oil change I put in fr3 with my t6 rotella. I have put a few hundred miles on it since the fr3 and it seems to be doing just as well if not just a bit better than archoil and its sure easier to find. I can walk into my local atwoods home and ranch store and pick it up right off the shelf. I do believe it is also less expensive. When you pay about 50 bucks for oil and another 20 bucks for a good wix filter archoil is another 44 ish bucks and to me is no better. So buy fr3 because it works well and wont break the bank on top of all the other materials you need to pull off an oil change. Thank you!!
