Reviewing this product is difficult, because unless you're an auto mechanic, it is difficult to determine if the cleaner is actually working. I'm not an auto mechanic, so I'll stick to what I know. Per the directions, I added 3 ounces to 15 gallons of fuel and drove for the next week until my tank was almost empty. I did not see an increase in fuel efficiency (i.e., increased mileage). My car did not run any better, and it still idled at around 850 RPM. I drive a car that's 16 years old and has 160K miles. It's a stick shift and still in great shape. I have a newer, more modern car, but I drive this one daily because driving a stick means you actually have to pay attention to every aspect of driving, and I love it.I almost always use a gas additive when I fill the tank, but I was hoping to get one to two more miles per gallon with this additive. I'll sum this review up by saying this additive performs about the same as the Lucas Upper Cylinder Lubricant & Fuel Injector Cleaner that I normally use. It just takes a lot less of this cleaner to do the same thing (3 ounces vs. 5.2 ounces). However, I can get more uses per dollar spent with this one versus the other cleaner, and that's enough for me to continue using it.

One thing I always do is maintenance on my vehicles (both personal and business) And I always like to use products like fuel cleaners to keep them running their best. When I came across this complete full synthetic fuel system cleaner from Liquid Performance, I decided to give it a try. After using it 3 times (at 2 and 1/2 ounce each time for my 25-gallon gas tank) I have noticed that my van is running a bit better and my gas mileage has seemed to improve which has really impressed me and I definitely like about this product. I like how easy it is to use with just adding one ounce for every 10 gallons and there is an ounce measurement on the side of the bottle that makes this very easy to do. I like how it mixes with the gas in my tank which allows it to clean my fuel system which I really like. And I again I really like that it seems to have improved my van's fuel performance which makes me really happy. Definitely a product that I will be purchasing more of for both my work van and car. 5 out of 5 stars.

I added this to all three of our vehicles and they all seem to run a bit smoother. There is really no way to tell how much this cleans your injectors but I would say for the price it is good preventative maintenance. This bottle will treat 160 gallons. I used two ounces in each vehicle when we filled up so we will get 8 treatments for the price which makes this a good buy. I also like that I don't have to buy and handle 8 bottles of cleaner to do the same job. I would recommend this if you are looking for a quality fuel injector or fuel system cleaner.

I can't be sure fuel system cleaner does anything but I use it because my car manufacturer recommends it at every oil change. Many gas pumps will now add this for you when you fill up (at various price points depending on concentration).I've done research on it in the past and the ingredient that's apparently most effective is something called PEA (polyether-amine). The more of this a fuel system cleaner has the more expensive the fuel system cleaner seems to be (there are many brands). I've used a product called Techron in the past based on many positive reviews. It costs less per ounce but requires more so this product is actually cheaper to use.My only issue with this fuel system cleaner is that I could not find what is in it. This is not detailed anywhere. Let's face it, we pour these products into our car and hope they do what they claim. Short of taking your motor apart you'll never really know so the manufacturer should show us some proof of value.I'm giving this 4 stars because it's good bang for your buck since it treat 90 gallons even at the highest recommended concentration, that's 3 to 6 tanks of gas depending on the type of car/truck you have. But the company should include something on its chemical makeup on its website to at least give use some clue what we're buying.

This product is good for doing maintenance on your fuel system, but the container it comes in tends to be leaky. I advise you to store it upright on a shelf in your garage and not in the trunk of your car. For the price, you get several treatments out of it, so you don't want it wasted by leaking out.

After two tank fulls of gas and using the calculation 6ml per gallon of gas, it didn't hurt the performance, but on the flip side I didn't notice a huge improvement either. Maybe gained an extra mile per gallon fuel economy. As far as power, it feels about the same, maybe a little better throttle response but nothing like night and day type of performance increase. Does it work, I really can't say one way or another but will update this review after I finish the bottle and report back if anything has changed.

It's always nice to have this type of fuel cleaner to put in before you fuel up your car. This bottle specifically only needs a little bit with each fill up. I haven't noticed a huge change in my car, but it does run smoothly and seems to be performing a bit better than before I used it. Probably better to get this kind than a random $2-$5 one from the store!
