I bought this in hopes to get an extra mile or two per gal. My Jeep has 130k and runs well but with gas prices being crazy now, the though was trying this as an experiment for saving money over time. Any other beneficial effects would just be a bonus. Well, I got the beneficial effects so that’s a plus. Noticeably smoother accelerating both from a dead stop and in passing at high speeds. I also seem to get a smoother cold start. Less friction noise. I haven’t however noticed any measurable up tick in gas mileage unfortunately. Granted it’s only been a single tank of gas. But for this stuff to at least have some effects in such a short period of time is great! I feel like a lot of similarly marketed products make grandiose claims and can’t deliver. Snake oil if you will. And I have tried a couple with little to no results. But this Liqui Moly does show signs of immediate effects. I’ll be paying close attention to see if these current beneficial effects sustain and how they wear off over the coming few thousand miles. I’ll definitely buy some more if it seems worth further use. Worth a first shot at least as it’s not very expensive.

I have a 2017 GTI that suffered from a hesitation when trying to accelerate quickly from a dead stop which could be quite dangerous when turning into traffic or turning left across oncoming traffic. I started out with 2 bottles of OEM VW fuel injector cleaner in back to back full tanks at $20/ea and didn’t notice any difference. A few months later I did the exact same thing, but used Techron based on the great reviews and the hesitation seemed to go away on those 2 tanks, but the problem came back. About 3 months later months later I bought 2 Liqui Moly and ran it in 2 tanks back to back, but this time and drove several miles at higher rpm’s using 5th gear on the interstates and and 3rd or 4th on surface streets. I am half way through the first tank without Liqui Moly and the hesitation has not returned. I was surprised to see my fuel mileage at 22 and 23 mpg respectively on the 2 tanks with LM because I drove it hard and with my normal spirited driving I only average 25 mpg. This stuff appears to be legit.

Used on a RX350 that was starting to lose MPG and during/after use we definitely saw a small bump in MPG but not as much as I was expecting as the car is still not getting the MPG it originally got. The car might have a deeper issue that this was not designed to solve but that being said, the fact that it did bump up the MPG a little and it did not otherwise cause any harm, I would definitely recommend and definitely try another bottle at next fill up to see if another treatment will do the trick

After two treatments, my Audi S6 runs smoothly after a cold start.

I successively ran two cans through my 2013 Mustang GT 5.0. The “feel” of the car is smoother and “peppier” by the second can. MPG didn’t seem to be affected but engine seems happier, i.e., the idle is better and full throttle appears to be improved. I will continue to use this product.

Item was of admirable quality! Quick delivery. Quality of the wrapping was fine.

Once the 90k miles on the injectors were cleaned with this, the car ran richer (lower mpg), then by the second tankful I was a good 1-1.5 mpg before I used the product. My O2 sensor readings are perfectly in spec, so I’m back to running true to optimum. 1 can in 1 tank. I’d recommend.

Out of all of the injection cleaners out there I think that this one is the best.Priced well and does the job really well.
