FR3 Friction Reducer is a 100% synthetic engine additive that enhances the host oil's wear reduction and lubricating properties. Hot Shot's Secret FR3 contants three proprietary 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 extend the base oil performance in shear stability, oxidation stability, film strength & especially friction reduction.An exclusive carbon nano lubricant, fills in microscopic irregularities in the metal surfaces. FR3is recommended for all diesel and gas engines, works with synthetic or conventional oils. Add it to a hydraulic system, power steering, engine oil or differentials. Use FR3 Friction Reducer oil in autos, farm and heavy-duty equipment, pickup truck and semi-truck engines. FR3 Friction Reducer works for any oil-lubricated system. Although FR3 is an industrial product, small two-cycle engines can benefit from it as well. Mix FR3 with fuel after adding it to your two-cycle oil. Use approximately 1.5 OZ (45 mL) per quart (.95 L) of oil. Add FR3 FRICTION REDUCER during a fresh oil change and leave in during entire oil change interval. Use in the next two oil changes after STICTION ELIMINATOR. Product will displace an equal amount of oil, do not overfill. Safe to add to engine oil, power steering, hydraulic system, and differentials.Safe to add to conventional or synthetic engine oil, power steering, hydraulic system, and differentials.

Q: Can I add this during the change of transmission fluid of my manual 5 speed to help prolong the life and fluid?

6 years ago
1 Answer
  • A: Per the manufacturer: Currently, we do not recommend the FR3 for manual transmission applications simply because we do not have enough test data and want to be sure our customers have no issues. We've tested the FR3 in a few manual transmissions and all of our testing has been successful. We don't foresee any issues, but we just don't have enough data to endorse it's use in that application, especially synchromesh transmissions.

Q: Can FR3 be used in conjuction with/used together with Stiction Eliminator?

7 years ago
1 Answer
  • A: FR3 and Stiction Eliminator can be used together, but there is not really a need; many of the components of FR3 are in the Stiction Eliminator. For the best bang for the customer’s dollar we suggest that they use Stiction Eliminator for the initial clean-up, FR3 for the next two oil changes and a maintenance dose of the Stiction Eliminator for the third oil change. Repeat cycle.

I’m SOLD on F3 on all my oil changes

6 months ago
I had my doubts about engine additives until I tried F3 by Hot Shot! I changed my oil 10 qts. and added 1 oz. Per QT instead 1.5 as recommended. I left the following day in my Ram 2016 3500 crew cab to Boise and got 20.3 mpg there and 21.8 return to Kingman AZ! More HP, low oil temperature and less engine noise!!

Still Have My Lifters.

I have a '21 6.7 Cummins bought new..zero miles and have been using FR3 since the first oil change. 100,000 miles now and still have my lifters. Rotella T6 5w-40 with FR3 always changed between 7500-11,000 miles. The change interval is a little high but I've since added a bypass oil filter.

Amazing product that actually does something!

8 months ago
Both the friction and stiction reducer work. My cold starts in my 47,000 mile 4.6 L Mustang are so drama free it's not even funny I also used it for my bicycle chain and the shifting is so crisp and quiet. It takes forever to get up to operating temperature because it is so slick and I noticed my fuel economy was up on the same route that I always take using the same driving technique I always use. I used it on the forks and the shock to eliminate any stiction that might have happened from plastic to metal contact. These guys are legit just ignore the YouTube videos not everybody's going to have a perfect experience but I can say in my case it was.

Yes, I recommend this product.
