## 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.
