Liqui MolyMoS2 Anti-Friction Engine Treatment | 300 ml | Oil additive | SKU: 2009

I’ve been using Liqui Moly products for decades, and this MoS2 anti-friction engine treatment continues to impress me. I recently added it to a high-mileage car, and it noticeably quieted the engine, especially on cold starts where timing chain noise was present. The improvement was clear, and it reinforced why I trust this brand.The value is excellent compared to other additives, especially given the performance and protection it provides. Liqui Moly has always been my top choice for German and imported vehicles, but it works just as well in domestic cars too.As a lifelong car enthusiast and someone who has worked around vehicles for years as a professional full time mechanic, I can say with confidence that Liqui Moly delivers on its promises. I’ll continue using this treatment with every oil change moving forward on the new to me Audi A6 3.0t prestige package with 138K.Overall: A trusted product from a trusted brand. Reliable, effective, and excellent value for long-term engine care.

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.

Liqui Moly Review – Worth Every DropAfter switching to Liqui Moly oil and additives, my engine has never felt better. Cold starts are smoother, engine noise is way down, and throttle response is sharper. I used their 5W-40 synthetic oil, MoS2 Anti-Friction, and Jectron fuel cleaner—and within a few hundred miles, I saw a small bump in MPG and noticeably better performance.The engine runs quieter, pulls harder, and even feels cleaner over time. Cera Tec gave me added peace of mind with long-term protection. It’s not just hype—Liqui Moly delivers legit results, especially for older, high-mileage engines.German-made, super effective, and absolutely worth the price.

I use this product every single time I get an oil change. I love this product because it decreases engine friction and makes accelerating feel smoother. I feel my gears shift much smoother and know that this product is working. It is high quality and perfect for my car with over 100K miles on it.

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.

I was skeptical about this product as I am all "miracle" products. But, after changing my oil in my 21 year old Toyota truck the first tank of gas got about 20 more, or so, miles than usual. My engine is substantially more quiet and my acceleration has improved. The lag is gone. This is my first tank of gas and my second tank seems to be on par with my first as far as improved milage. So far... the stuff seems to work.

I have been using LiquiMoly Mos2 for years in my turbocharged mini cooper. I had to replace my valve cover a few months ago and upon inspecting the valvetrain, there is very little to no buildup of deposits. I feel the performance of this additive makes up for the additional cost to an oil change and has helped to keep my engine in top condition.

I decided to try Liqui Moly MoS2 Anti-Friction Engine Treatment on my BMW N55 engine, and after several months of use, I’m impressed with the results.Installation: Simple to use—just add it to your engine oil, and it works alongside your existing oil without any complicated steps.Performance: The engine feels smoother and quieter, with noticeable reductions in noise, especially at idle. Throttle response feels more precise, and there’s a slight improvement in acceleration.Oil Consumption & Engine Wear: Oil consumption has stabilized, and the engine runs cooler, which is great for long-term durability. The MoS2 treatment creates a protective layer that reduces friction and wear on engine components.Fuel Economy: There's a small improvement in fuel efficiency, especially on highway drives.Final Thoughts: Overall, the Liqui Moly MoS2 treatment has made my engine run more smoothly and efficiently, and I feel confident it will help extend the engine’s life. It's a great product for anyone looking to reduce friction and protect their engine.
