Review: Not really useful - The engine check light disappeared for two days and came back. Before every time I reset the error code the engine check light would not come back before few days, but after using this product the it would come back next drive.
Review: I’ve had this product work before, and it’s been good. This time it did not, and I actually used the warranty/guarantee process and they stood by their assurance and refunded me! I would absolutely buy the product again, my car is a 1995 BMW with <75k miles and it failed CA smog, but using this made it pass before. After the failure this time I had the car checked and it needed an O2 sensor, which fixed it for good, hopefully. But I would absolutely recommend this product to others - if the car isn’t suffering from something major, it DOES work! And the company stands behind it.

## Questions & Answers

**Q: How do I get my money back it did not work**
A: I once submitted all the required paperwork for the money back and they never sent me a dime.  I did see slight lowering of some numbers but very little.  Basically buy it but don’t expect to actually get a refund much less twice the amount

**Q: Does this clean oxygen sensors and catalytic converter?**
A: This product cleans out just about everything totally from the gas tank to the exhaust tailpipe. Severely clogged systems may require a second treatment but anyone that lets it get to that point is probably going to need a lot more than an oil change and a few spark plugs.

**Q: Does it have to be done right before the test or a week before is okay?**
A: i've done it 4 days before testing...and this is if you're failing due to a worn out cat converter;  if you're not passing due to HC, that is a tune up and maybe new O2 sensor...

**Q: Will this help with the egg smell I get once in a while after I floor it. Doesn't stink all the time only once in a while**
A: Yes, it will.  The "rotten egg" smell is unburned fuel passing through your car due to dirty injectors, dirty intake valves, dirty compression chambers, dirty catalytic converts and dirty EGR valve & passageways, and dirty spark plug tips.  This product cleans all of these areas.
