I've been using the Performance Formula One Shot nearly every tank in my 98 Jetta TDI year-round since I bought the car in 2005. I now have over 315,000 miles on the car and have no problems with any of the stock injection components (injectors or injection pump). Whenever I forget to re-stock the supply in my trunk and don't add any to a tank, the car smokes more, and is noticeably louder (slightly louder engine knock - especially when cold), and isn't as easy to start when cold (cranks over 2-3 times before firing instead of just 1 with Stanadyne). I also notice a slight increase in power (throttle response) with the additive. I definitely recommend it!!

I've been using Performance Formula One Shot for most of the 100,000 miles on my Chevy Duramax. I have been putting in an 8 oz. bottle every other gas tank filling. My truck engine runs like a top with no issues and plenty of power. There is no way I can attribute this performance to One Shot, but on the other hand I do believe it has kept the injectors clean and provided me with a smooth running engine.

In fact, I just ordered another case. I wouldn't be without it as injectors are very expensive to replace.
