LIQUI MOLY MoS2 Anti-Friction Engine Treatment | 300 ml | Oil additive |SKU:2009

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.

This engine treatment has been excellent! I've noticed smoother engine performance and reduced friction since using it. The 300ml bottle is a great size and easy to use. The Liqui Moly brand has a solid reputation for quality automotive products, and this MoS2 treatment lives up to that standard. My engine runs quieter and feels more responsive. Highly recommend this product to anyone looking to protect and improve their engine's performance!

I have seen marked improvements with the engine performance on my '06 Volvo S60 and will be using one for every oil change. The engine is also noticeably quieter, which is a big plus for me. I recommend this product.

This exceeded my expectations. I have a 2007 Subaru with 179,000 on it. It was very noisy lifter wise and ran very rough. Now it purrs like a kitten. Gas mileage has improved slightly too. Excellent product!

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.

Will always use after oil changes. Everyone has their opinion but this is made in Germany and used on the expensive European cars and they run on the autobahnen where the drive at alot faster speeds then us. So it is a really good product. I drive an older vehicle and it keeps it quiet and engine smooth.1 time every 3 months. But again everyone has an opinion on what works. Look up the cars on the autobahnen in Germany.

Love the product in our 2018 Ram 1500 5.7.

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

Disminuye un poco el ruido de motor

Car much smoother to drive after its application.
