About Liqui Moly

All LIQUI MOLY products are created by close solidarity with the automotive, two-wheel and commercial vehicle industry. That's why Liqui Moly solutions are always on par with state-of-the-art technologies and sometimes even a good distance ahead. The recipes for LIQUI MOLY high-tech products are largely based on our own developments, that we continuously test and develop. The LIQUI MOLY full range, with more than 4,000 products, offers you lubricants, additives, car care products and chemical repair tools with integrated use guarantee.

LIQUI MOLY offers the matching motor oil for every vehicle in the world. Liqui Moly engine oils have a variety of approvals by German and overseas car manufacturers or fulfill the requirements of the producers. And, even here, there are still differences: A manufacturer approval means that the oil fulfills certain minimum requirements. But LIQUI MOLY goes beyond those requirements and develop oils that, for example, have a higher cleaning performance than what is required by the manufacturer.

Every mile driven costs a tiny bit of engine longevity. The reason: Friction and wear. A creeping process, that is often accelerated by poor fuel quality and deposits of old lubricants. However, regular maintenance of the oil and fuel circuit can usually restore engine performance to its original level. Without much effort, but with a great deal of effect. When it comes to gear oil a similar thing can be said.

The fact that LIQUI MOLY products shine, and, with a high level of innovation, deliver what they promise, is confirmed again and again by independent testing institutions, in which we regularly pass with flying colors. Approvals by the automotive industry and the fulfilling of the highest specifications are also a matter of course.

Liqui Moly Evap and AC Cleaner
To help a few of you on the fence about this product, I used to pick up various evaporator cleaners from auto parts stores to clean out my Mercedes AC systems. For some of those cleaners, spray can form did an okay job, but oftentimes times it required reapplication quickly or two cans to really kill off the smell. Recently, those cans seem to be less potent and I was still getting odors even after spray and new filters. I bought this skeptically as it is costly compared to 20-dollar cans of cleaner, but for my 2019 GLS this did just the trick. Those who have ML or GLS Mercedes know that this is a really bad problem that is difficult to clean and maintain. The lemon smell is not overbearing and after about a day, I am not sure I can smell it. Second, the product pumps a liter of solution through your HVAC system and the spray atomizes and seems to work the way through the vents. Once I complete the full cycle and dried it out, no musty odor and I feel confident this product will last at least a year or two before reapplication. Was it worth the price, in my case yes, I hate the smell of musty Mercedes AC systems and it would drive me mad if not addressed. One Note: the system comes with a 3/8" quick connect for air compressor, if you are using 1/4 fittings know that you should buy the 1/4 male thread fitting. Also the tank of cleaning solution LM20001, does about 5 car cleanings.

Not what I expected, but good addition
This is a nice unit that is designed to clean your evaporator, while it is installed in your car. I was looking to flush my A/C lines and got this. Glad I did; It is a quality kit (a little pricey) that can be used in the car and will really help me out with my house A/C. Simple design is appreciated.

Question Posted by Julius
I was under the impression this would come with at least one sample packet of the cleaner solution. I cannot find the cleaner solutions anywhere on your website (Active-2P AC System Cleaner 20001). Please let me know where i can purchase the cleaning solution.
Answer (Posted by FCP Euro Products Team)
The cleaning solution was unfortunately discontinued by Liqui-Moly earlier this year, we no longer offer the solution.
Question Posted by Harland
I am confused as to how this will flush an ec system. The nozzle isnt large enough to seal on any hose? Also once a year? With a cabin air filter? Is this just meant for the ducting?
Answer (Posted by FCP Euro Products Team)
The cleaner is supposed to be sprayed directly onto the AC evaporator and recommended once per year. It wouldn't be a bad idea to replace the cabin air filter as well at this time.
