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.
Great Product! Great Company to Deal With

I really like the FR3. It seems to quiet my 05 F-250 6.0 a little. Will say that the engine seems to start easier, and the dieseling noise is not as pronounced. Have use Hot Shot’s Secret since I purchased this truck, and all of their products do what they say and a very high quality. Even called and spoke to them about product usage, and they were extremely helpful and knew what they were talking about. Again, great products, great people, and as always…GREAT RESULTS!!

Barry Bishop (verified owner) –
FR3 oil additive has very noticeably improved engine performance and mileage in every gasoline powered vehicle I have used it in. Improved fuel economy, increased acceleration, and a much smoother running engine is what I have experienced using it. I have used several other products offered by Lubrication specialties and every one has performed exactly as claimed. These guys really know their products and are quick to answer any questions I have had. Customer Service has been a pleasure to speak with, their shipping is affordable (and often free!) and fast, and has always arrived well packed and in good condition. I am a very satisfied customer as well as a customer for life. Thanks LSI !!

I’ve used FR3 in my 1966 classic Volkswagen. These engines are air cooled, and heat is a killer on these engines. It maybe just wishful thinking but I fell that it’s quieter using FR3. Now I wonder what benefit would Stiction Eliminator do for the gasoline engine.

5 out of 5 FR3 really works!!!! Outstanding product!!!!
Carl (verified owner) –
I have been testing FR3 in my 2008 Toyota Prius. I am consistently seeing 7-8% improvement in mileage on a car with 248,000 miles on it. Amazing stuff! I really like FR3. It actually DOES what is claimed. This is a quality product, NOT “snake oil” junk. My engine is quieter, smoother and getting better mileage. Since this product really works for me, I have recently added it to my wife’s 2006 Toyota Prius, my 2003 Ford Excursion 6.0L diesel, my push mower, my 4-cycle weed-eater, and my commercial 60″ 27-hp zero-turn mower. As soon as I receive more product, I plan to use it on our 2006 Pontiac Montana, the tiller and our 10k watt generator. Great stuff!!!! I run Amsoil 100% synthetic in everything I own, if anyone was curious. Now, FR3 is also standard issue for me with every oil change. Keep up the good work LSI !!!!

FR3 review
Monty McKinzy (verified owner) –
I recently changed oil in my 2010 Ford F-150 and added FR3 also. On startup, you can really tell how it has reduced friction and runs smoother than before…..The claim of increased fuel economy is the truth as it has extended a tankful to 1.5 times to work….roughly about 6.5% on miles per gallon.

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!

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!

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

Can you just add the FR3 by itself first? or should you start with the stiction eliminator?

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.

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.

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!

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!

Troy, absolutely! Full or semi synthetic and conventional oils are completely compatible. Thanks!
