Excellent Engine Treatment - Highly Recommended!
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!

Quality stuff since the beginning
Liqui Moly Review – Worth Every Drop After 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.

Proven Protection and Performance – My Go-To for Decades
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.

Seems to work
I'm not a mechanic but I like to keep my car maintained, and this oil treatment has made a noticeable difference in the smoothness and peppiness of my engine. Would definitely use again.

I noticed a difference in engine performance
Installed this Molly in my Range Rover . It didn’t quiet the loud start up lifer noise but man did it smooth out the engine on idol . I was skeptical when I started the engine . I waited and let the car idol down . Took about 15-20 minutes for it to take effect . Once I increased the rpm’s that’s when I noticed a difference. Seems to bring back torque as well . Very smooth and quiet . I would recommend this product.

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.

Don't leave home without it!
Every oil change should end adding this. Will smooth rough idles, power acceleration and extend engine life. Once noisy Mercedes purrs like new. Chrysler 3.6 L especially benefitted. Diesels improve MPG through friction reduction. Family has been using moly products since the 1960s. Pure science, this. It works!

Ha llegado super rapido. Excelente producto LiquiMOly. Lo utlizamos en el NISSAN Sentra 2004 XE motor 1.8. QG18, lleva sus 379.577 kms. y aun continua trabajando el auto al 100%, va mas suave mejor a relanti, menos ruido. Debo reconocer que el Auto lleva su aceite SAE 15W40. El aditivo lo llevamos usando 2 años. y el auto parece nuevo: no hace ruidos. el motor NO tiene fugas ni botes. El motor lleva 3 lts de aceite (indicaciones del Manual NISSAN).; por lo que solo aplicamos la mitad del aditivio LiquiMoly. unos 150 ML.. la otra mitad la utilizamos para el sgte cambio de aceite. El aceite utilizado es SEMISINTETICO SAE 15W40. y un filtro de aceite BOSCH, cambios cada 7 mil kms. No soi un amante a los aditivos; pero es el unico que utilizo. El motor funciona con más suavidad y regularidad, se reduce el ligero consumo de aceite y combustible. Hace que el motor marche de forma más estable y disminuye las averías, han sido 16 años con el motor XE 1.8QG, el motor nunca se ha bajado. Sigue trabajando perfecto. Cambios de Aceites y Servicios en Tiempo y Forma. Se recomienda LiquiMoly Anti-friccion.

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
