I have a 2022 Kia k5 and I use this every oil change. When it comes, it’s packaged very well and you do get a bang for your buck! Shops are charging upwards of $20-30 to have this done. Instructions are super simple and can be done within 30 seconds! Works amazing!

Before putting this in was having a bad misfire upon starting that even caused the checked engine light to come on intermittently. Since running this additive through the vehicle about a month ago the engine catches immediately on startup and the check engine light has stayed off... Have also gained more power on the highway and getting an extra 20 miles out of a tank of gas. I have been noticing a slight return of the misfire in recent days so I may have to add another bottle to the car or a more "dedicated to a specific problem" additive fairly soon or have my fuel injectors inspected but this product did do some good for the car. 2003 Honda Element EX with 175,000 miles.

Great price, Great product. I use it every 5k miles when I get an oil change and I can tell a difference after I use it when my car idles- the RPM's don't fluctuate as bad

Use it once a month for new cars or twice a month for older cars. Does make a noticeable difference.
