Review this product

What do users say? AI-generated summary

Overall, it is rated very positively, with users reporting effective fuel-system cleaning and smoother engine performance. Better throttle response, a steadier idle, and a slight improvement in fuel economy are also frequently mentioned, particularly in vehicles with related issues or when used preventively. However, the results aren’t always noticeable, and it isn’t expected to fix serious problems or deliver dramatic changes.

    Tested in a car and a motorcycle.
    Slightly better than the simple injection cleaner from the same company.
    Edit: Don't expect any difference if your engine has less than 80,000 km.
    The product is an injection/fuel delivery system cleaner.
    If it has nothing to clean, you will NOT see a difference!
    This is not a miracle cure; it does exactly what it says on the box.
    Of course, someone can use it periodically, in new engines, purely for prevention, every 10-20,000 km.

    Good fuel system cleaner. But for Direct Injection engines it doesn't work miracles. There you need the (very expensive) Direct Injection Cleaner from Liqui Moly. I hope I helped.

    I used it on a Toyota Auris 2007 1.4, the product is fantastic, it stopped the misfiring at idle and when I press the gas it pulls better. Surely it did its magic somewhere inside. I believe that if you don't see a difference, then there is probably another problem. Many people buy it, try it and expect results as if their engine was replaced with a new one. I have used similar additives of the same brand in other cars with the same results, but I feel this one did a bit more. It works. Even if your car doesn't have any issues, it's good to use it from time to time to keep your engine clean and healthy!!

    I bought a used motorcycle and changed the fuel filter, which was quite dirty. I put about 150ml in an 18L tank and rode 120km, keeping a steady 4,500 rpm for 70km. From the beginning of the ride to the end, there was a significant difference, the bike felt refreshed. Don't expect the performance to change as if you installed a tuning program though. It does the job but not miracles.

    The product is designed to clean the injectors and the fuel system. It does not "clean" the engine. If, for example, you have spark plugs that need to be changed since they were invented, you will not see any improvement. However, in properly maintained engines, it does work. And very well, in fact. In a 2007 MX5 1.8 with 110K, I saw a huge difference in consumption (mixed cycle range ~550km while before I barely saw 400). I have, of course, never skipped a service. However, during the service, they do not clean the injectors or the fuel network that collects dirt from "questionable quality" fuels. And that’s where this comes in to make a difference. Also, as a friend mentioned earlier, one bottle probably isn’t enough. I have used three in three consecutive fill-ups with 100 octane, and that’s when I saw the difference.

    It does a very good job. I use it once a year or every 15,000 km. It should be noted that I use it on a 25-year-old vehicle and a 10-year-old one.

    As I wrote in another review for a similar product,

    It is difficult to draw conclusions easily after just one use, isn't it?

    As a brand and in terms of product quality, Liqui Moly is well-known in the automotive industry.

    I cannot easily express an opinion after just one use of this particular product.

    Perhaps someone will notice a difference if they use it more frequently, rather than using it after a certain number of kilometers as stated on the packaging.

    For example, if someone takes a trip from Athens to Thessaloniki, they should use one container on the way there and immediately use it again on the way back.

    Perhaps this way there will be a clearer picture with frequent use.

    Quite a good product. It improves the start-up and operation of the car as long as it is in the tank. When new fuel is added without the Liqui Moly Prο-Line Fuel Injection Cleaner, the car's performance changes for the worse.
