One bottle and a full tank of gasoline. I usually then don't add fuel until it is nearly empty.

My car was idling and running a little rough at low speed. Too much city driving.Put in a bottle at fill up and things smoothed out almost immediately. Very satisfied.

We put this in a older Sonata and saw improved gas mileage after that first tank!

the check engine light came on several times on our 2002 VW Passat. the scan tool showed a lean fuel mixture code each time after the code was cleared. The engine has about 90k miles and the original fuel filter. Rather than replace the filter, I first tried this product and the light has stayed off for about 2 weeks. Fingers crossed that the problem is fixed. Yeah, I know I’ll have to replace the filter at some point, but for now it looks like this product has improved our fuel flow.

Product works well, but a bit pricey compared to other products available.

Started using this product after I paid the dealer to clean the car's fuel injectors because it was sluggish.Haven't had any problems since.

I bought these to see if they would help my Honda Pilot. I gotta say, I noticed about a 10 % increase in mileage. Nothing scientific here, just more miles on the odometer before I needed gas. Really noticed it on a long trip. Anyway, I think its helping and I've bought them again. My thinking on products like these is this: If your engine is clean -either new or well maintained- you may not notice any significant improvement. Like putting clean dishes in the dish washer. There's no difference but it doesn't mean the dish washer isn't working. If your engine is of average use -like apparently mine was- then this helps clean out whatever unwanted gunk is in there and helps your engine run a little better. If your engine is really bad, then when this stuff cleans it out, well, that gunk has to go somewhere. It gets burned up with the gas and your car may actually run worse until it clears it all out. These are the only scenarios I can think of that would explain why some people swear BY this stuff and others swear AT it! I know its a generalization and of course there are varying degrees of quality and additives from brand to brand, but I think its a pretty fair summary. Also, I add some to my 2 cycle fuel mixes for my string trimmer, snow blower etc. They're not fuel injected but they have all those small ports and needle valves and such that I think products like these can also help keep clean.
