Liqui Moly2030 Pro-Line Gasoline System Cleaner, 500 ml, 16.91 Fl Oz (Pack of 1)

With the usual stock of High Millage Seafoam being out everywhere I looked, I sought an alternative. Luckily M539 recommends many of LiquiMoly's products, so I felt like I could trust this one. Thus far, seems to have done the trick. I'm noticing my engine running smoother and quieter. Worked pretty fast too, just a single tank of gas is all it took. (so roughly 300-400 miles) And the can itself is very convenient, with the included gas spout.

After using Liqui Moly 2030 Pro-Line Gasoline System Cleaner, I noticed an immediate improvement in my car’s performance. The engine runs smoother, acceleration is more responsive, and fuel efficiency has slightly improved. It also helped reduce rough idling and hesitation. Definitely a great product for keeping the fuel system clean and the engine running at its best!

Works great and you can definitely tell a difference. It really works best for me when I fill up with non-ethanol gas, and put the cleaner in at the same time and drive on a road trip.

It does what it says. Gained 2-5 mpg and helped lower engine knock on a 2014 Fiat I have.

This product works. I run it in my 2017 Audi Q5 and my wife’s 2019 Jeep JL. I will use once a year to help maintain our fuel system in both vehicles. Using this in conjunction with valve clean and the jectron. Helps keep our vehicles running amazing all year long. My suggestion would be to use this once a year and to use the VALVE CLEAN cleaner they make every other fueling and use their JECTRON/DI JECTRON product 2-3 times a year. For my wife’s jeep, I use this complete fuel system cleaner, and JECTRON the most. keep in mind these are preventative products and can help when you do have carbon buildup, but the best investment is to use this before you ever have a problem. Since my wife’s jeep has a port injected motor these treatments work especially well at keeping carbon buildup from being an issue, if you have an Audi like mine that is direct injection this cleaner along with DIJECTRON is your go to. Keeping carbon buildup at bay will help with the longevity of your motor and your investment. It’s very easy to use worth the money and cleans especially well.

I'm sure it's working but I haven't noticed any difference

Great , L Moly makes great products, sisters 10year old car got a weird engine code related to gas and running rich or lean, I sent 4 bottles of this to her and told her to use is back to back, well the engine code is gone, so it was dirty gas or dirty injectors or dirty valves , every 10,000 miles I normally try to use 2 bottles back to back of this cleaner or other cleaner driving at highway speeds on long trip to clean everything out ( normally gas in the US and gas from quality gas stations already have cleaners in them, but it never hurts to keep the system clean, way cheaper than a mechanics bill )

Exelente producto
