A+ product, no snake oil
This is worth the money and is cheaper than FCP. It smells like proper detergent for fuel system. Use about one a month for best results. It functions as intended. The color brightness has a green hue to it and it's an easy way to clean your injection system. The containers was a little dinged up but it did not leak. It comes with a perfect screw on funnel which most does not. Highly recommend for preventative maintenance.

Typical excellent quality from LiquiMoly
I use this every 2-3 months in several different trucks. Helps to clean out any deposits left by using inferior gas that you may have had to fill up with on occasion. LiquiMoly specifies this for use in port injected and carbureted engines, but my trucks have direct injected engines and I’ve encountered no issues using this. I imagine LiquiMoly just hasn’t updated their product description as the vast majority of new trucks these days use direct injected engines, often in combination with turbochargers. Great product.

Best cleaner that's out there. Works well, and can be used at every fill up. Use on a 2018 Yukon Denali

Annual Fuel System Maintenance from LIQUI Moly!
Fuel additive should be added as part of the annual maintenance oil change or every 7500 miles. Begin with a complete fuel system cleanser and one full tank of fuel, then add fuel injector cleaner on the second tank and valve cleaner on the third. Apply gasoline additive before filling the tank. In this way, the agitation of filling the tank with gas better combines the fuel additive with the gas. Fuel injectors, valve covers, and fuel systems that are dirty may cause your vehicle's engine to misfire, poor gas mileage and RPM needle bounce while driving. Regular use of gasoline cleaners and decent fuel from Chevron or Shell yields the best results. They can help with the removal of harmful deposits, the prevention of new deposits, and the augmentation of existing deposits. The education and user support team at LIQUI Moly is quite attentive. You can contact them via mobile app, email, or phone. Stefan Braun, LIQUI Moly's Application Specialist, advised us on oil and gasoline additives for all of our vehicles.

I’ve been using this for a while now and it just works!
I’m usually skeptical about cleaners, additives etc claiming they will do something…with LiquiMoly they aren’t kidding their product will really do what it claims. Just by smelling it you can see how strong and concentrated the cleaner is. I use this on my 2014 Chevrolet Tahoe every now and then to keep everything in the fuel system working properly. You notice a difference almost immediately, the throttle response is improved and my MPG has actually gone up by about 2-3 mpg it’s definitely doing something. Anything LiquiMoly sells works like magic from my experience so…try it you won’t find anything else that works better in my opinion.
