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

Good stuff, if you want to keep your engine in good shape as long as you can this stuff is invaluable when changing your oil. With all the low viscosity oils and cylinder lining variances these days this stuff is just about mandatory as far as insuring that you don't have to worry about your engine.Make absolutely sure you change your oil at regular intervals, do not follow the manufacturer suggestions these days of 7-10k mile oil changes, those recommendations are nothing but an early grave for your engine so they can sell you a new car since you won't get more than 150k miles on an engine using lengthy oil change intervals. Stick to the 5-6k mile oil change intervals and you'll get over 200k out of modern engines.

This is a great product for high mileage engines. Added it to my work truck and noticed a difference right away. The engine got quieter especially the tapping lifters. I noticed an improvement on my mpg as well as smoother idle. Highly recommend this product and will not hesitate to purchase again in the future especially with the affordable price.

Awesome product, if you want your vehicle to last as much as possible keep using this regularly or at least every other oil change, and you will notice the difference in the engine performance without getting oil leakages.

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.

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.

Smooths out the engine idle and also gives a compression boost. Awesome stuff!

Worked amazing on my wife’s car, stopped the ticking on the valves
