Reputable, reasonably priced fuel additive to clean valves, with handy dispenser. Not all comes out.

Honest review of Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml , blue @ $8.68 at time of order. I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some injection cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work. Likes: Amazon Prime shipping, returns and refunds within 30 days of receipt. Reputable product. The price point seemed reasonable, especially if it works as advertised (10.1 ounces, single treatment can). Comes with dispensing attachment for easier pouring. Dislikes: The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside. Meh: I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps. Hopefully this honest review helps someone decide about this product.

This stuff really works fast and improves mpg like you won’t believe
Size: 300 Milliliter
I’ve tried many other types of fuel injector cleaners but this brand is amazing. I ran my truck down to less than a quarter of a tank of gas and poured it into the tank. I then drove 30 miles to an appointment and spent an hour in the appointment on the way home I noticed my mpg had gone up significantly. My truck tells me how many miles per gallon. I’m getting as I drive. I had gotten a code and I replaced the mass air filter and found a slight crack in an air hose, which I replaced that help with my code a little bit, but cleaning the fuel injectors with this product made such a significant difference. I just simply had a hard time believing it, but it’s true. I’m done with all those other brands of fuel injector cleaners which never really seemed to help much if you really want an amazing experience give this product to try.
