Amazing product
I recently tried Liqui Moly MoS2 Anti-Friction Engine Treatment on my Dodge Viper, and the results were impressive. My V10 engine had started to feel a bit rough, with minor ticking noises and slightly sluggish response under hard acceleration. After adding the treatment during my oil change, I noticed a difference almost immediately. The MoS2 formula coats the internal engine components with a protective layer, reducing friction and wear. Within the first 100 miles, my Viper’s engine felt smoother, and the startup noise was reduced. Acceleration became more responsive, and the overall performance felt closer to the way it did when the car was new. I also appreciated the peace of mind knowing that this treatment offers extra protection during high-performance driving. For anyone looking to maintain a high-powered engine in peak condition, Liqui Moly MoS2 is an excellent addition to regular maintenance. It genuinely helped keep my Viper in top shape and running like a dream. Pros: Noticeably smoother engine operation Reduced startup noise and ticking Improved throttle response Extra layer of protection under high load Cons: Works best when paired with fresh oil Overall, I strongly recommend Liqui Moly MoS2 Anti-Friction Engine Treatment for anyone wanting to preserve engine health, especially in performance cars like the Viper.

Strong Leadership for an Old Engine
I add this to my Volvo 850 because old machine must be maintained with discipline. Engine with many kilometers is like a factory—if there is too much friction, production suffer. This MoS2 treatment go inside oil and create order between metal parts. Before, engine little noisy on cold start. Some vibration, little rough. After adding, engine run calmer and smoother. Idle more stable, like well-run tractor plant. I appreciate simple engineering. No marketing circus, no nonsense. Just pour it in, drive car, and machine behave better. Very practical solution. People always promise miracle in bottle. This is not miracle. This is stability, efficiency, and proper management of mechanical system. My Swedish brick now run with good discipline

Enhanced Engine Performance and Protection
Having used various engine additives over the years, I've found that Liqui Moly MoS2 Anti-Friction Engine Treatment stands out for its tangible benefits. This 300 ml can of oil additive is designed to enhance your engine's performance and longevity by forming a high load-bearing lubricating film on all friction surfaces. The results are quite noticeable. My engine runs significantly smoother, especially at higher RPMs, and there's a definite reduction in engine noise, making for a quieter and more controlled driving experience. It truly makes the engine feel like it's running with less effort. Beyond the immediate improvements in smoothness and sound, this additive is also geared towards prolonging engine life by reducing wear. This is a critical factor for anyone looking to maintain their vehicle's health over the long term. I've also observed a slight but consistent improvement in fuel efficiency, roughly around a 10% increase in miles per gallon, which is a welcome bonus given the current fuel prices here in Colorado. While it's a supplement to your regular engine oil, its effectiveness in providing an additional layer of protection and enhancing overall engine operation makes it a worthwhile investment. In my experience, the cost of the product is quickly offset by the gas savings, proving its value.

Shake it violently
Need to shake and the shake again. All the of the content settle to the bottom. Pour oil in the can and shake again. Almost needs a bead in it like paint cans have. Engine is quieter. All direct injection engines are noisy. This helps. Gas mileage improvement? I have a heavy foot. I'm not consistent enough to tell you yes or no on that. When adding to the oil put a shake it or shake that song on. Lol it's awful

I started using powdered MoS2 additives in the 70s' starting with an MGB/GT and then a Jag XKE. Years later I switched to the Liquid Moly product. I would never own a car and not use it. It makes the engines on a luxury sedan and my wife's SUV run smoother, quieter, and more responsive. In upstate NY winters I never even think about cold starts, especially after no use for several days. Using Liquid Moly is a no brainer in ANY vehicle.

If it’s from this brand, just buy some and love it.
I trust any product I have ever used from this quality German manufacturer. Pro tip – careful when you pull off the sealed cap, it’s splattered the substance and ruined a shirt, but it’s not made for shirts. It’s made to have your engine last. No complaints!

This is not snake oil!!! It works!!!
I had came across this product several times before and never gave it a shot because I didn't know much about liquimoly before. Until few weeks ago, a buddy of mine bought a BMW M3 and he asked me what oil he should change. If any of you knows M3s, you should probably knows the rod bearing issue they have. Because of this M3s basically have to have 10w freaking 60 oil in their motor… or 5w40 if you drive in winter… Since I hate Castrol and Mobil is not that good anymore. I found liquimoly while I search on the bimmer forum. I soon to find out that it is actually the best oil brand in German and their liqui-moly is one of the proven working friction modifier beside zinc. Their oil is probably the best oil for M3s period. So my buddy bought the 5w40 oil only and I bought 2 cans of this to mix with Amsoil for my Mustang GT and my girl friend's Sonic. A week after the oil change, my buddy told me that he did notice that the oil temperature raise a little faster compare to 10w60 but that should be expected since 5w40 is much thinner. Other than that, it's too early and very hard to tell a difference by changing from a full synthetic to another full synthetic. I will wait until the next oil analysis to see if there is any improvements. On the other hands, for my Mustang and my girl's Sonic. Oh man, what a great difference this product made. First, I change oil on the Sonic and pour this terrifying looking liqui-moly into the engine. (I got to say it scare the s**t out of people that were watching me doing the oil change lol) Then I start the car, walk up to the front of the car and try to listen if there is any decrease in noise the engine made. Unfortunately, Sonic's motor is chain drive, which is very loud and there is nothing you can do about it. So I reseted the car's MPG, returned the car to my girl and asked her to drive car like she normally drive. The result was very well. Sonic's MPG raised from 31.8 (should be lower, because she drove 6 hours on highway before the photo was taken) to 33.8. More than 6% increase in MPG sounds very good to me, well worth the money I spent on the product! Now for my Mustang GT, the difference is huge. This 5.0 coyote engine can be loud at idle. It's V8 after all. However, as soon as I pour this magic moly in the engine and start the car. Oh man, what a whisper quite engine it became (beside the Borla exhaust anyway lol) I mean literally all the lifter noise and the metal clapping sound was gone. All I can hear is the engine is running smoothly and pulling air in the intake. Heavenly music to my ear. I showed it my buddy and he was amazed as well, but we both agree that we should better not add anything in those BMW engine though… Who knows what can went wrong if you know what I mean… Anyway, I was sold on this product. I'm glad that I found something that it's indeed not a snake oil. I may try the cera tech next time as well. Good job Liquimoly.

Excelente producto
Los productos liqui moly nunca me decepcionan, uso este, el limpiador de inyectores y el de lavado internos en cada servidor y mi motos suena y se siente suavecito y ligero como nuevo de paquete, ya es un auto con 10 años y nunca a presentado falla. Si se siente que reduce la fricción y protege el motor, tal vez parezca caro usar esos productos pero se amortiza el costo al mantener un motor en excelentes condiciones
