I have used this product for some time now and it appears to work very well. Combined with Liqui-Moly Ceratec, I have noticed a noticeable improvement in Mileage. Yes, it is subjective, but I am very aware of how many Kilometres I get out of a tank of petrol. It has definitely improved since using these tow products.

Yes you can buy cheaper and I did for many years but then I heard & read reviews about this product and gave it a try in a variety of cars from small capacity 4cyl engines through to Toyota & Holden V6's. The results showed after 80 to 150 km city driving and the results are fantastic.Much smother & responsive engine performance which gives better fuel economy regardless if it's your Nanna driving or you like to tromp the foot down - in a safe way of course...lol..I no longer use any other brands regardless of how cheap they are.

I'm always a little scepticle about these additives and what they claim but I was blown away by how much zing this puts back into your car. I have a 2007 Subaru Forester that's just undergone head gasket replacement, heads machined and valve stems re-sealed so I was looking for some additives to give the rest of the engine a bit of a refresh. LiquiMoli Petrol Injection Cleaner starts working straight away and you can literally feel the difference in responsiveness and improved power after a few kilometers. After a tank of fuel and this can of additive the car is more responsive, accelerates smoother and better and fuel economy has improved a little. After posting about this on an online forum a few mechanics even came forward and said it's something they always add ... MoreI'm always a little scepticle about these additives and what they claim but I was blown away by how much zing this puts back into your car.

Only been doing short runs in my vy commodore, decided to put this cleaner in for a 300klm trip to clean out the cobwebs! Now definitely runs smoother, idles better and can definitely notice performance! Best cleaner I’ve used!
There are many similar products in the shop and this stands out with the packaging “made in Germany” and he handle nozzle to get to the fuel tank. In terms of the content, it does the job perfectly. Used to have the Nulon products and always been using 98 Ultimate for my BMW … this truly more psychological advantages and have a piece of mind. It does boost up the octane as most of them do and the car will feel more responsive
I bought an 06 TJ Jeep Wrangler about 4 years ago. Ever since Ive had it the car has always been sluggish. Ive done many mods to this vehicle including replacing the coil pack rail, spark plugs, fuel pump, placed decent headers on it, put 2 1/2" cat back exhaust, larger throttle body, high performance cat, enlarged the air intake and force feeding the air into the manifold. In doing all these mods I was hoping to gain more HP. With much frustration and blowing my budget I gained little to no extra HP and still the car wasnt responsive. I used the round of the mill injector/fuel system cleaners. Results were pathetic. I took the car to 2 profesional injector cleaner shops and still no change in power. I stumbled across this injector cleaner so I thought Id try it and ... MoreI bought an 06 TJ Jeep Wrangler about 4 years ago. Ever since Ive had it the car has always been sluggish.

I used the round of the mill injector/fuel system cleaners. Results were pathetic. I took the car to 2 profesional injector cleaner shops and still no change in power. I stumbled across this injector cleaner so I thought Id try it and see what happens. Nothing ventured nothing gained. Guess what............. After a 100km trip to the Gold Coast the motor suddenly freed up. The motor revs more freely and the HP increased dramatically. Where I had to drop the car into 3rd gear to get up hills I now shift from 6th gear to 5th gear. This stuff really works. I am stoked with the results and the more I drive the car the better it seems to run. I cant wait to add another bottle to the tank but I will do it with the next 10 thou service. Off road the low range performs smoother and the car is more responsive (touchy on the throttle) as well and no more pinging or shuddering. Very impressive. I definitely recommend this stuff over any other injector/fuel cleaner. $33 dollars well spent. Do yourself a favour and use this german engineered product. You will be surprised how good it is. Added bonus is that it doesnt hurt any components in your vehicle. Even my Mrs is now happy to drive my Wrangler. Shes says its like the difference between day and night. For even better performance and fuel economy I now run Dino Tabs which ups the octane levels dramatically. I know the TJ's are renouned to be crawlers off road but I now have one that performs well on the road as well. Its not a drag racing machine but for a Wrangler its impressive.
Noticed impressive results almost immediately. 25km into the tank and my Subaru was running much smoother. Smoother acceleration, a nicer idle and much better power delivery. This stuff really works.
My old girl was running a bit sluggish, even after a tuneup/service and when I tried Liqui moly it gave her a NEW lease on life.Smoother handling and so far better fuel economy. Worth every penny.
Hard to say whether this product is any different to the performance of my car. I have been running 98 fuel for nearly nineteen years, in this Vy SS Commodore. I did notice that fuel consumption was better after adding Liquid Moly, that's good enough for a 4 star rating. I will continue to add to fuel tank with every oil change.
Put this into my fuel tank just prior to filling up. Car has some ping at low RPM under load and was using a bit more gas than factory. After running this through, noticed ping issue resolved and getting 1 litre per 100kms better fuel economy. Good stuff. Worth giving this a go.
