Recently used a can in my 2008 535i with 115k, I used a full can on a half tank then filled up ad went on a long drive to a wedding. After about 30 miles in I noticed a little difference in smoother acceleration and a slightly quiter idle/highway speed. Very happy so far and will use again in a couple months, i had zero issues with this product and good results for such an easy-to-use application

 I have a Audi a6 3.0t. I am in Audi, Volkswagen and Porsche, technician and enthusiast. I was looking for a Volkswagen injector additive to clean out my fuel system. And this was suggested to me. On the first used, I noticed a huge difference in performance and my car drove Way better and smoother from a smoother idle to smoother acceleration. Definitely recommend on every other fill up.  even gives a slight increase in mpg.

Ive always treated my engine with TLC. From time to time, I provide engine Tonic like LIQUI MOLY fuel Injector cleaner, before a long trip.

I've been in the power generation field, (diesel, gasoline, turbine) and am always looking for a good detergent additive, this one is the best I've ever seen. I operate a small engine and generator shop and find that even ethanol-free gasoline is only as clean as the tank and handling allows. Adding this to my customers equipment has made a significant difference in the overall operation of their equipment. I added it to my Ford F-150 with 170,000 miles and it has made a real difference! Now my customers buy it, use it and love it! Glad I found this fantastic product!
I am normally hesitant to buy products off of the “snake oil” section of AutoZone. For the most part, those products are completely useless. Not Jectron. I use it every other tank in my 1998 Jeep with the 4.0 liter straight six. I had a rough idle that I could not correct on an otherwise mint but old engine. I had done every typical Jeep fix and none worked. Everyone said that’s just how they idle. But I knew it wasn’t because it wasn’t always like that. A friend of mine who is a Volvo mechanic recommended Jectron to me. The car smoothed out after one tank. And it has stayed smooth for three years. My running theory was carbon buildup but who knows? It worked. Give it a try.
This is a very specialized product for a race car’s fuel injector to stay clean. This product runs through engine and keeps it clean. It was recommended for race car category cars with high HP. The changes are not immediately visible but in the long run U have faith that this type of products will increase the life of parts and keep the engine in working condition. I highly recommend this product to others.
The only one that works! Tried many other fuel injection cleaners with no noticeable difference. Tried this when on sale and it works. The mpg in my 2008 Lexus dropped to 28 mpg. Started using this and it returned to over 30 mpg. For best results use it at least 3 or 4 times in a row. On my third tank full, I notice white smoke out the tail pipe. Then it cleared up and back to over 30 mpg on the highway. I even noticed it idling smoother and better acceleration! I buy it every time it’s on sale. It pays for its self.
Upon purchasing a CPO Volkswagen Atlas, I researched the best fuel injector cleaner for VW. Liqui-Moly kept coming up at the top of the list, so I searched on the Auto Zone app and found it available at the nearest location to me. I was pleasantly surprised to find one can available at the location. Product seems to have worked well and I will continue to use both Liqui-Moly as my preferred brand and Auto Zone for purchasing.
This product is working good so far. I checked each cylinder via borescope and it showing promises. My piston carbon buildup is getting cleaner in just one use. Maybe multiple use of this product might clean it all. Only time will tell.
Had clogged injectors on my Hyundai accent. Car was Running like crap and ck Eng light on. “Low fuel rail pressure” thought I was gonna have to tear into injectors which would have been a major pain. Last ditch effort tried this product and after 2 days after adding…. Shazam!!!! Prob solved and car running 100%!!! Never would have thought as I have tried many diff fuel additives for different things and never worked.
