20002 Cera Tec Friction Modifier (300 ml)

Engine became smoother and quieter after use. Slight improvement in mileage, but not significant. Good product for refinement, but a bit expensive.

Very nice product. My diesel car engine is working very smooth.Noise level is reduced.

I used this in my New Ertiga(2021 model). Car is comparatively less travelled and in 2 years its only 9700 KMs. After using this I got a noticeable noise reduction just after 10 km. After running this for 1000KMs the engine vibrations are completely gone. I can hear only ignition and tyre noise when the car is running 100 KM/Hr. All vibrations and noise are reduced surprisingly. I got this at Rs. 1717 Pros: 1. Reduction in engine noise 2. Reduction in engine vibration 3. Car cold start gets smooth 4. The car feels like butter smooth even running at more than 100 km/s Cons: 1. Cost is high(with this price one can get a complete 3 Ltr new engine oil) but if your vehicle is crossed at least 20,000 KMs it's worth buying Personal Recommendation: I tried this in my car to check its performance and use, my car is less than 2 years old and average running is very low. If your vehicle is driven more than 20,000KMs then I think it's worth buying. But if your vehicle is brand new or less driven then no need to consider this and do consider the money you are spending on a product that may not help you a lot on a new or less driven engine. I did not find any major mileage difference so it's not helping me to get high mileage, but yes, the driving experience is great with this as this smoothens the engine noise and vibration. 10 Oct 2025 Update: Not sure if its ethenol side-effect or ceratec is now loosing its strength, but the engine noise is increased a bit, i can feel the vibration and noise inside the cabin, also the mileage is dropped marginally. Will do a routine service to check

I used this in my 2013 Chevy Captiva, run only ~34k km, during the annual oil change 3 months back, and also started using Liqi Moly super diesel additive. I can clearly see three things that have changed 1) Reduced noise from engine bay to cabin 2) slight improvement in mileage (10%) full tank to full tank method. 3) smoothness in engine during idle and on the run while acceleration/pick up Now planning to use diesel purge next time when I do fuel top up. And will continue this ceratec with every oil change hereafter. Updated: Changed the engine oil during routine annual interval, a couple of months back, odo reading at 38k. Used following items Liqui Moly Engine Flush Ceratec 2000 Shell 5W30 Post changing oil and topped up with diesel along with liquimoly diesel additive 1806, vehicle performance has increased considerably, smooth as showroom delivery, nil vibrations felt inside cabin, definitely increased mileage and better acceleration response from engine throttle.... Those who are on the fence don't....start using Liqui Moly products and see them transform your car engine n fuel lines. The only caveat I can add is regular servicing of your car as per OEM specs is a must. These are only great additions to the regular service, don't think these will convert a bad maintanened car into a gem..... Let's be practical Couple of weeks back did my Chevy Captiva annual service again....this time odo stands at 43k. Items used again Liqui moly engine flush, pour this into existing engine oil, start engine n run for 20-30 mins idle, stop engine, flush out old oil. Liqui moly ceratec 2000 - once old oil is flushed, pour this into the oil sump first and then add Engine oil, I use Shell ultra helix 5w30. Car runs butter smooth.... Will add diesel purge during next fuel tank fill up as its done last 2 years back. Must use products from Liqui moly....go for them

Ceratec works like a magic after 400-500km of running it showed its magic and made my engine like butter smooth hoping it will make even smoother

Good product

Packaging’s is sketchy. But the container is intact. Using it : Used Half of it in honda jazz 1.2 vtec petrol with 32000km. Now it runs even smoother.

Effective Friction Modifier for Enhanced Engine Performance I recently added Liqui Moly Friction Modifier to my 2018 Tata Tiago's engine, and the results have been noticeable. This product is designed to reduce friction and wear, and it has made a tangible difference in engine smoothness and performance. Since using this friction modifier, the engine feels noticeably smoother, and I've experienced a slight improvement in fuel efficiency. The product is easy to use—just add it to the engine oil, and it blends seamlessly. The reduction in engine noise is also worth mentioning; the Tiago now operates with less mechanical noise, contributing to a quieter ride. The overall engine response feels more refined, which is a welcome enhancement. Overall, Liqui Moly Friction Modifier delivers on its promises and is a worthwhile investment for anyone looking to extend engine life and improve performance. I highly recommend it for those seeking to get the most out of their Tata Tiago.

Good product

Hoy le realice el servicio a mi Camry 2016 le coloqué un limpiador de motor de liqui moly, como siguiente le puse un aceite toptec de liqui moly y como final le puse este aditivo. También le puse un filtro de aire y de aceite k&n. Y las bujías de rutenio. En unas semanas a actualizo mi opinión y les comento al respecto. Actualización: Después de 2 semanas, es increíble el cambio en carretera larga el auto me da 20-30km por litro. E incluso si antes que le hiciera el servicio era muy poco lo que se escuchaba y ahora con este es insepertible el ruido. Solo se escucha el ruido de las llantas al girar.

Motorn har fungerat bra och går riktigt bra, men efter tillsatsen har motorn lugnat sig och känns som den är både tystare men förbrukar även mindre. Måste köra med den mer för att kunna ge en bättre bedömning. Men hitills verkar det fungera väl. Ska köpa en till flaska till min Q5 3.0

Comme beaucoup d'acheteurs sur Amazon j'étais sceptique, je me suis renseigné, regarder des vidéos sur YouTube pour savoir vraiment si l'effet de ce produit était réel. Alors, pour info j'ai commandé ce produit pour une audi diesel de 2015, ensuite c'est lors de la vidange que je l'ai ajouté. Les résultats sont vraiment là, ce qui est très impressionnant pour un additif de 300ml qui ressemble à du milkshake. Dès le démarrage les bruits moteur (cliquetis etc) disparaissent à tel point que je me suis demandé si j'halluciné.. après avoir roulé quelques kms( environ 5km) pour faire circuler l'huile dans le moteur et faire un appoint si nécessaire, quelques bruits reviennent ( je suppose que le produit commence a ce mélanger à l'huile chaude )mais c'est plus la même chose, le moteur est clairement, vraiment, vraiment moins bruyant sur une échelle de 1 à 10: je dirais que avant j'étais à 6/10 en termes de bruit après avoir ajouté le produit au moteur Dès le début j'étais à 3/10. Ensuite après avoir fait environ 200km..ben le bruits de cliquetis et général du moteur est passée à 2/10 voir 1/10..c'est vraiment impressionnant pour un additif. Seul ce qui ont utilisé ce produit comprendront mais effectivement le moteur devient "léger" à la conduite on a l'impression qu'il ne force pas pour ce faire solliciter dans les montée en régime etc. Info : J'ai pré- mixé 150ml du produit avec de l'huile neuve que j'ai versé dans le moteur je m'explique : après avoir mis environ 1 litre d'huile neuve dans le moteur et 150ml pure de cerratec. ensuite j'ai mis encore de l'huile et le pre-mixé. Je pense que ce produit fonctionne bien si on mets vraiment la bonne quantité d'huile (j'ai utilisé un récipient gradué) et si une partie de ce produit et pré-mixé. Par contre si vous avez de réel problème mécanique( pièces cassé, défectueuse etc) il ne pourra rien pour vous, mais je le recommande à 100% vous ne le regretterez pas. Bonne journée à tous.

I recently experienced a remarkable transformation in my 2016 Mustang Ecoboost, thanks to the LIQUI MOLY Oil Additive Cera Tec 3721. As someone with a passion for automobiles and a background as a software engineer, I'm always on the lookout for ways to improve my vehicle's performance.

After researching potential solutions, I decided to give LIQUI MOLY Cera Tec 3721 a try. And I must say, I was pleasantly surprised by the results. The primary reason I opted for this oil additive was its promise of ceramic wear and tear protection.

The moment I started using it, I noticed a significant reduction in engine noise, especially the knocking sound that had been bothering me. It provided a smoother engine performance, and the difference was noticeable. What impressed me even more was the impact on fuel consumption. As someone who loves to travel and has explored six states during my time in the USA, fuel efficiency is a key concern. LIQUI MOLY Cera Tec 3721 not only improved my engine's performance but also led to lower fuel consumption. This means fewer stops at the gas station and more miles of adventure. Moreover, being a mentor and research assistant, I appreciate the science behind this product. It's clear that LIQUI MOLY has put considerable effort into developing a high-quality additive that benefits both petrol and diesel engines. This is the kind of innovation that I believe will shape the future of the automotive industry. In conclusion, LIQUI MOLY Oil Additive Cera Tec 3721 has not only fixed the knocking noise in my Mustang but has also enhanced its overall performance. It's a product that aligns with my goal of staying at the forefront of technology and innovation in the IT sector, even when it comes to my car.
