Review: Better Performance, Power, and Fuel Economy. Used in my Older Vehicles. Excellent Results. - 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.
Review: 2008 Trailblazer SS - 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!

## 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.
