Engine Treatment, 300 ml | MoS2 Anti-Friction | Oil Additive | Pack of 2

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!

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.

super product, quieted down engine noise

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.

It’s a good product

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!

About 500 miles ago, our first try in the crankcase of our 2006 Scion Xb 1.5L, NA 5spd with over 160k mi. GREAT mileage improvement of 5 mpg even in the cooling fall/winter weather! No matter what we did, our little CUV box never improved its average city/hwy miles like this since we purchased it used in 2017. The only add-in was Liqui Moly MoS2. While sticking with 5,000 mile oil changes, we've tried many fuel and oil additives, professional injection cleaning, iridium plugs, OEM filters... and more to get mileage near 30 mpg. I've even been driving like the grandpa I am. This Anti-Friction treatment works. We've also started using Liqui Moly manual transmissions oils in this Scion, and our ancient 1986 VW Cabriolet. Both cars saw improved shift feel and reduced synchro grinding. After all these years, this is our new favorite brand!

Great product, GM four-cylinder on a smaller engine need liquid Molly, quiet the engine down. GM recommends 5w20 oil. The problem is the rings. Don’t hold up on the vehicle and you start using this oil,What works for me is changing the oil to 5W-30 and using Mos2. Anti-friction. Using thinner oil in my opinion will cause a lot of problems well in the long run. In Germany, same engine they use 5W-30. Of course the engine doesn’t hold up on the long run using 5W 20 that’s good for GM cause you’ll have to buy a new car. Some of the mechanics also say change your oil every 3000 miles, equals the hot turbos burn up the oil and viscosity goes down. This is my opinion and opinion of a lot of mechanics.
