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.

Dangers of Chlorinated Paraffins

This test shows that in a period of 100 hours at 300°F, a popular retail oil-additive begins to oxidize, causing sludge and stiction.

The Hot Shot’s Secret FR3 was subject to the same test conditions; remaining crystal clear, with no signs of oxidation on the steel bearings in the test tubes.

Oil in a turbo charger can reach temperatures of 400°F, which, over time breaks down engine oil causing stiction.

    Question

    Is this OK to use in a Toyota Tundra 4.7L V-8 with 205,000 miles on it? I always take truck to dealer for oil change. Should I just add a small bottle or replace oil one time with nothing but FR3?

      Absolutely! FR3 works great in both diesel and gasoline engines, and are compatible with synthetic, semi synthetic and conventional oils. FR3 is recommended at a 1.5oz per quart of engine oil. An 8oz bottle will treat 5 quarts, which would be slightly under treating your 7.5qt system but a small enough amount that you could top it off without draining or changing the oil. If you have over a thousand miles on this oil change I’d recommend waiting until the next oil change and asking the service technician to add about 10 or 12 oz of FR3 to your oil. Thanks!

      Stiction Eliminator and FR3 can be used together, but you’ll see more cost effectiveness when using them separately. FR3’s benefits are much more apparent when added to an already clean engine. Stiction Eliminator is recommended initially and at every third oil change, with FR3 inbetween, thanks!

      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!

    5 out of 5 Great for Zero turn Hydraulic systems

    (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

      Stiction Eliminator is recommended initially to clean the engine, you’ll see FR3’s benefits more quickly when the engine is already clean and the benefits are more apparent. FR3 contains some cleaner technology similar to Stiction Eliminator to ensure it gets to the surface inside an engine, so if you’re far away from your next oil change or do not have Stiction Eliminator, you can use FR3 initially.

      Hi Gary, please replace 2 quarts of oil with Stiction Eliminator on the first oil change, followed by 18 oz of FR3 for 2 oil changes. Then, 1 quart of Stiction Eliminator followed by 18 oz of FR3 for 2 oil changes, and repeat. Hope that makes sense, thanks!

      Mark, you’ll add FR3 the same way as Stiction Eliminator, FR3 replaces the recommended dosage of oil. For most vehicles, you can add the recommended dose to your existing oil and still be within the recommended levels on your engine oil dipstick.

    5 out of 5 Smooth quiet ride

    (verified owner)

    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

    5 out of 5 Great Product

    I wanted to write and say thanks for the 8oz FR3. In the order I placed I got this free and decided to try it in my 2015 F250 with the 6.7 Powerstroke. I am new to the diesel world but knew they were a little loud and rough. I had just changed the oil in the truck and had about 200 miles on the new oil when I put the FR3 in. After about 10 minutes of driving around I noticed everything was a little quieter and when I came to a stop the idle was much smoother. I also noticed a 2 mpg gain with this and using the EDT on every tank.

    I got this to try out and I’ll say, it makes a decent small ball bearing lubricant so far! Not too thick and doesn’t stink of petroleum since it’s synthetic. It actually smells a bit like an energy drink.

    Question

    I have used the diesel product in my ’04 Duramax to clear up injector failures and it worked beautifully. I also used the oil additive with great results.

    So I was wondering if there was a stiction eliminator for gas motors and is there an oil treatment for gas motors as well? Something similar to the nothing short of amazing results I got from the diesel additives.

      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.

      Admin (verified owner)

      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!

    My name is Jonathan. I own a Ford F550 a 2005 model year with 6 liter Power Stroke diesel. It’s been modified so it carries about 15 to 17,000 pounds daily. I discovered Hot Shot’s Secret by following an online forum and I can’t be happier as a user of Hot Shot’s Secret! I’ve noticed cooler operating temperatures, primarily that the engine runs so smooth and so quiet. I know that the Hot Shot’s Secret is definitely helping me out! My fuel economy is outstanding. I’m getting on average between 12-13 miles per gallon. I’m also using the [Friction Reducer] and the [Diesel Extreme] for the fuel, trying to treat every aspect of the engine. The customer support is outstanding! I’m getting preventative treatment, rather than reactive treatment. Hot Shot’s Secret, that’s the way to go!
