Liqui Moly Hydraulic Lifter Additive | 300 ml | Oil additive | SKU: 8367

I’ve been using this Liqui Moly hydraulic lifter additive and it works well. it helped quiet down some noise from the engine during long rides, which was a nice surprise. the 300 ml bottle is convenient for regular use, and i feel it keeps the lifters running smoothly. simple to add during oil changes and seems to enhance engine performance without any fuss. happy to have it on hand for maintenance.

Freed up sticky valves and lifters on my 1995 Mercury Mystique 2.0 Litre Automatic. The car had been stored for about three years and would not start due to sticky valves and hydraulic lifters. I applied one bottle along with an oil and filter change, turned the engine over manually for about 5 minutes until I could feel the engine running smoothly and no more snapping valves and springs. At that point it started right up running completely smooth and silent.

I used it for the first time. The Mazda's Sky Active engine is known to be somewhat loud, due to the direct injection which is often confused for loud lifters. It does seem to have lessened a little, and it can't hurt to give a little extra maintenance to an older engine.

I put in a bottle of the Liqui Moly and aftr driving th vehicle the little "tic-tic-tic when it was hot was nearly gone! I was concerned that because product is quite a bit thicker (higher viscosity) than the 5W-20, I was cocerned that the additive would make all of the oil a single thinker viscosity by making the polimers that change the viscosity as other similar additives have done in the past. So, I called the product assistance line and asked that very question! The rep assured me that wouldn't be a the result of using this addiive! I'll keep an eye on the viscosity when the engine is cold since the viscosity is "supossed to be) about the consistancy of water (5W) tto get oil to all of the engine upon startup. To answer the questions below: the appearance is opaque, it is unknown if it acually reduced friction, the cost is about equal to other similar products, no leakage was observed, the vehicle engine continues to operate smoothly but there is no wayto determine if there has been any cleaning action! However, the apparent sticky lifter noise is somewhat lessened, so far! We'll see........

I tried this Liqui Moly lifter additive on a car that had some ticking noise and it did make a difference, but not immediately. After driving for a bit, the noise became less noticeable and the engine felt smoother. From what I understand, it works by cleaning internal oil passages and improving lubrication, so it may take some time to fully show results rather than fixing the issue right away . It is important to mention that this is not a miracle fix. If the lifter problem is mechanical, this will not completely solve it, but it can help reduce noise in mild cases. The bottle came sealed with no leaks and everything looked fresh when I opened it. Overall it is worth trying if you have minor lifter noise, just keep realistic expectations

Have used this product before and have liked how good it works for my vehicles. Would recommend product. Good quality and price.

My older Escalade has a tapping noise at startup and it subsides after I drive for a while. I thought this product may reduce that noise, but it didn’t help at all. My issue is likely bigger than just adding something like this.

I work in a shop and just tried this product for the first time , worked better than expected. Will be using it on other applications.

Works like a charm!!

Excelente Producto

Seems to have quietened down my timing chain in my 2014 Audi 3.0TDI

Efficace sur une 320i e36. Le clac clac au démarrage a été complètement réduit et a quasiment totalement disparu. Néanmoins, il m'a fallu rouler un bon millier de Km après avoir mis l'additif pour qu'il commence à faire effet
