## Description

desertcart.com: Hot Shot’s Secret Friction Reducer FR3 32 oz – Treats 21 Quarts of Oil – Synthetic Oil Additive, Reduces Friction, Protects Engine, Improves Performance and Fuel Economy for Gas & Diesel Engines : Video Games

Review: This stuff works! - Been using 64oz in every oil change on a Cummins ISX every 15,000 miles for a little over 2 years now. Raised oil pressure from 34psi to 38psi at about 1,400rpm and almost cut about 1/2 gal oil consumption between oil changes. Motor currently has 1.2 million miles on overhaul. Best additive on the market in my opinion.
Review: Great product - Every 5000 miles at oil change

## 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.

Every 5000 miles at oil change

### ⭐⭐⭐⭐⭐ 2008 Trailblazer SS
*by T***E on January 29, 2025*

I'm a former auto mechanic from the days before computers ruled the automobile, so I mainly do not use oil additives. However, my LS2 has had more noticeable lifter chatter over the last couple years. I tried Seafoam in the crankcase as directed, drove it 100 miles and changed the oil. It made zero difference. After researching loud lifter knock for my other car (2006 300 C), I stumbled across this product but also Stiction Eliminator (bought that too). I drained 20oz of oil from my LS2 and then added 20oz of FR3. I didn't have to put on more than 20 miles before I took note of how quite the lifter chatter is, full honesty. I gained roughly 5lbs of oil pressure when data logging and the engine is much more responsive. Directions state to change the oil first but since I'm real close to changing it again (with AMS Oil), I feel it's worth more to run it the current oil and then flush everything out for a fresh change. For the 300 C (5.7 Hemispherical), the knock was loud, had it at a reputable engine shop and they said it needs a new engine, for the low low price of $8,700). Had it towed back home and it sat for 3 weeks. Added Friction Eliminator to the oil and ran it for 20 minutes. The noise is almost completely gone now. I definitely recommend both products!
