Watch Video »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.

I recently used the product FR3 in my 1999 Mercury Grand Marquis gs and I have noticed that the engine is operating noticeably quieter and appears to be running smoother and it also has a little more pick-up-and-go !! I am satisfied at this time with FR3 and will get more.

What are the differences/uses between the FR3 and the Stiction reducer? Also, I’m joining the NHRDA and you are sponsors for them, what kind of sponsorship do you offer drivers in the classes? I will be registering as a contingency driver also if that helps at all.

Here’s an article that helps clarify the differences between the products: http://www.hotshotsecret.com/stiction-eliminator-vs-fr3-whats-difference/
Welcome to the team!
In the past we have focused on primarily professional drivers (semi trucks, fleets, owner/operators, hot shotters, etc) so we decided to branch out further into the performance side of diesels and are the title sponsor of the NHRDA and Pro Street class sponsor of the Outlaw Diesel Super Series.
Just by registering for an event at an NHRDA event you’ll receive a product, plus we provide complimentary samples of EDT at both NHRDA and ODSS that treat 100 gallons of fuel. At this time we haven’t finalized a Hot Shot’s Secret contingency plan, but if you stop by the booth and let us know how we can help, I’m sure we can figure something out. Thanks Sean!

Question
Rusty –
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?
(0) (0) Watch Unwatch
Admin Spencer W. (verified owner) –
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!

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

RJ –
Can you just add the FR3 by itself first? or should you start with the stiction eliminator?
(0) (0) Watch Unwatch
Admin Spencer W. (verified owner) –
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.

Keith Ferguson (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

I also noticed a 2 mpg gain with this and using the EDT on every tank.

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 fr3 be used in a new motor or wait for a break in period before use
(0) (0) Watch Unwatch
Admin Spencer W. (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!
