## Overview

Hot Shot's Secret FR3 Friction Reducer is a premium 100% synthetic engine additive designed to enhance oil performance by reducing friction and wear. Compatible with all gas and diesel engines, it boosts horsepower and fuel economy by up to 5%, cuts engine wear by 43%, lowers operating temperatures, and reduces valve noise. Ideal for every oil change, this 8 fl. oz. powerhouse uses patented nano lubricants to restore compression and extend engine life.

## Description

FR3 Friction Reducer is a 100% synthetic engine additive that enhances the host oil's wear reduction and lubricating properties. Hot Shot's Secret oil friction reducer comes equipped with three patented synthetic lubricants with prototypical properties in comparison to metallocene polyalphaolefin (mPAO) or PAO synthetics of the same viscidity.An exclusive carbon nano lubricant — the formula's anti-wear component — fills in microscopic irregularities. This component's synergistic properties extend the base oil's performance in film strength, oxidation stability, shear stability and friction reduction. Its properties can also add to the oil's efficiency and protection. The 8-ounce FR3 friction eliminator is recommended for all diesel and gas engines. Add it to a hydraulic system, power steering, engine oil or differentials. For best use, apply one treatment of friction reducer engine additive every oil change on auto, farm 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 engine's oil.With the ability to improve your vehicle's performance by increasing fuel economy and horsepower up to 5% each, friction eliminator is recommended for any equipment or vehicle and works in synthetic and conventional oil. Use 1.5 ounces per quart of oil. Topically that is 8 ounces for cars, 23 ounces for trucks and 64 ounces for semi trucks. FR3 displaces the same amount of oil. Do not use in combination with Stiction Eliminator and other aftermarket oil additives.

Review: This additive really works and I can tell a difference in my older engines which I use it in. Those engines are a 318 ci 5.2L V8 in my 1998 Dodge Ram 1500 SLT Laramie and a 225 ci 3.7L Slant 6 in my 1974 Dodge Dart Swinger. Engine performances are more efficient and run cooler because they don't have to work as hard as without the additive. At each oil change use 8 oz of the product along with the fresh Mobil Synthetic 10W30 oil. You will see a difference.

## Questions & Answers

**Q: Can this be used with full synthetic Mobil 1 oil?**
A: I use it with mobil 1

**Q: Why not aircraft?**
A: FR3 is a friction modifier.  I don't see why it could not be used in aircraft if the 1.5 oz. per quart ratio is followed.   I have personally used the 1 oz per quart ratio with no adverse effects.   ***I would  never exceed the recommended ratio provided by manufacturer ***

**Q: Can you mix the stiction eliminator with the fr3?**
A: From what I can find on the manufacturer's site, use stiction first. Then use the fr3 with the next oil change.

**Q: Can i use the stiction eliminator first then add this the next oil change?**
A: Yes you can. I put it in my engine half way thru the oil change then at the next one.

I’m not sure if it works or not but I’m sure it did no harm lol, I’ll give it a 4 stars as it didn’t make my RzR 800 any quieter (engine making typical Polaris knock)
