Liqui Moly MoS2 Anti-Friction Engine Treatment | 300 ml | Oil additive | SKU: 2009

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.

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

I’ve used Liqui Moly MoS2 in my 2016 Chevy SS (LS3), and the difference was noticeable pretty quickly. After adding it during an oil change, the engine felt smoother on startup and quieter overall, especially during cold starts. What this additive does is create a molybdenum (MoS2) protective layer on internal engine parts, which helps reduce friction and wear under load . In a performance car like the SS, that translates to smoother revs and a slightly more refined feel when accelerating. I also noticed: Less engine noise at idle Smoother throttle response Engine just feels more “free” and less strained It mixes easily with oil and works with standard oil capacities — one 300ml can is designed for about 3–6 liters of engine oil, which fits perfectly for most V8 setups . This isn’t some magic horsepower mod, but it definitely enhances engine feel and protection, especially if you care about long-term wear or run your car hard. Overall, for the price, it’s a solid add-on for performance and peace of mind. If you’ve got something like a Chevy SS or any higher-performance engine, it’s worth trying at least once.

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.

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

this is a good product i like the good value and noticicble smoothness of engine after adding to oil keep it upright the cap is tricky it can leak if tipped.

Definitely works as intended. Seemed to quiet the motor down a little on start-up even. I had researched the product pretty extensively before buying it but this type of product has been around a long time and was used by our military and nasa. Great for the price.

Lowers valve chatter, makes engine run smoother, improved fuel mileage, great quality, and personally I choose liqui Moly products over most. You can’t go wrong with this. High or low mileage engines will thank you.

My car is known for having what they cai typewriter tick from factory on new car, if you add a bottle of this every other oil change it gets rid of that tick 100% some people add it every change it depends how noisy it gets but this stuff definitely works

Good genuine product reduces vibrations and increases performance as well as fuel efficiency

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

It's good to use every other oil change, has helped with mpg, noise, and seemingly oil endurance. Between my first use and most recent oil change, the oil was in much better shape and colour after using this. Worth it. Totally worth it

Car much smoother to drive after its application.
