## Questions & Answers

**Q: Will this fix a 2005 sentra that goes up hills only in 1st gear, but has no cel codes? if not, what should i buy?**
A: So my mechanic said try this... I have poor acceleration in my car, especially when going up hills. he said my catalytic converter is clogged. So try this before replacing my converters.

He said to add two bottles to 12 or more gallons.. run it to 1/4 tank.. add another bottle bring to half a tank and run it till 1/8 a tank. 

He said highway to get it warmed up nicely

**Q: Cómo es el método de uso?**
A: No funciona.

**Q: Do I use this on a full tank of gas? Or in a tank that's near empty?**
A: I believe I used it with about half a tank of gas. Suburban has 40 gallon tank so..... 
I have had no cat. converter or O2 codes since running this through system.

**Q: Do these cleaners work for the bad smell that cats put out sometimes?**
A: All I know is that it is supposed to help your vehicle pass emission inspection. If you follow the directions it might not work. The ratio of 16 oz : 16 gal didn’t do any difference to my vehicle. I don’t recommend this product
