## Overview

Liqui Moly Cera Tec 20002 is a premium 300 ml ceramic-based oil additive designed for petrol and diesel engines. It reduces engine wear and friction by creating a durable ceramic layer, leading to smoother performance and improved fuel economy. Compatible with all motor oils and filter systems, it withstands extreme temperatures and protects engines for up to 50,000 km, making it a must-have for performance-conscious drivers.

## Description

CERA TEC is a high-tech ceramic wear protection product for all motor oils. CERA TEC reduces friction and wear due to ceramic compounds that withstand extremely high chemical and thermal loads. Prevents direct metal-to-metal contact, thus increasing the engine service life. The low-friction effect reduces fuel consumption in gasoline and diesel engines. CERA TEC provides wear protection for engines, transmissions, pumps and compressors. CERA TEC should be added to the oil and is self-mixing. Sufficient for 5 liters of motor oil. Provides protection up to 50,000 km. Not suitable for use with wet clutches.

Review: It Works! (Mustang 2016 ecoboost knocking noise) - 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. This product turned out to be a game-changer. One of the issues I had been facing with my Mustang was a persistent knocking noise, which can be quite concerning for any car enthusiast. 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. As someone who values the longevity of my vehicles, I wanted to reduce engine friction and wear as much as possible. This product did exactly that. 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. I highly recommend it to anyone looking to improve engine performance, reduce friction, and achieve better fuel efficiency. It's a small investment with significant returns for your vehicle.
Review: My 2018 Mustang GT BBQ Tick went away but came back. - Update 1-26-2019: The BBQ/Typewriter tick came back this morning. So, I'd say that if you're trying to use the Ceratec to quiet the tick, it will work for a little while, but will eventually return. I don't think there's anything else that can be done to quiet the tick and it's a crap shoot if you get it serviced. In my case, it only ticks during warm up after the transition from high idle, and goes away completely once the entire engine is fully warmed up, so I'm just going to live with it. I'm still giving the Ceratec a 5 because it did reduce my friction enough for a small MPG improvement, so I believe it works as advertised and I'm not going to blame them for not silencing the tick. Update 1-20-2019: After a few days with only the one bottle poured in, my tick came back. Since one bottle is only 1/2 the recommended concentration for the 10 quarts in a 2018 Mustang GT, I bought another bottle and added it and the tick is now gone again. We'll see if it lasts. I can tell you that my fuel economy has improved. I have a little over 11,000 miles now and I always display my fuel economy meter and I use it. I've never reset my average fuel economy meter since the day I bought the car new. I've been pretty well stuck at 21.6 MPG for the last couple months. Since I've put in the Ceratec, my average fuel economy has increased to 21.8 MPG, so it's jumped 0.2 MPG in roughly 2 weeks. With over 11,000 miles included in the average, it takes a pretty significant improvement in friction to make that average move that much in that short a time. Even if my tick comes back again, I'm sold on Ceratec for the friction reduction alone. I'll update the review again if the tick comes back. Original Review: My 2018 Mustang GT developed the infamous BBQ/Typewriter tick immedaitely after my first oil change. I used Mobil One synthetic at 3500 miles on my first oil change. I did my 2nd oil change at 10K miles with Mobile One, but the tick was still present. After seeing people on YouTube having success eliminating their tick with Ceratec and after reading the one other review of a 2018 Mustang GT owner here on desertcart, I decided to try it. I ordered 1 bottle. It arrived on a Friday and poured it in immediately after I got home from work. It's an hour drive one way to work, so the engine was at operating temperature, where, in my case, the tick goes away. I only get it when the engine switches from high idle to normal idle after a cold start and the tick is quite loud for at least the 15 minutes it takes for me to get to the drive through where I get my morning coffee, where I can really hear the tick echoing off the wall. After pouring it in, I started the car and let it idle, but didn't really notice any change. I then took it for a drive and did some hard pulls to get the engine to rev under load to the red line. After that, I put the car in the garage until I drove to work on Monday. When I went to the drive through to get my morning coffee, there was no tick! It was gone! I listened real hard, but all I could hear was the normal direct injector pump noise. Then, after my hour long drive to work, I left car running and got out to listen. With the hood closed, it was quieter than at any time since I bought it. It was virtually silent. Even the DI pump noise was barely audible. The car also sounded and felt different during the drive to work. The engine seemed like it was smoother somehow. It might have been my imagination, but after the silence in my parking spot at work, I wouldn't be surprised if the engine did run smoother. At any rate, I only used 1 bottle to treat the 10 quarts of oil, which is half the amount the mfg says to use. So, I'll see how long it lasts, but it definitely worked even at half its normal concentration. I highly recommend it for anyone who has the 2018 Mustang GT tick.

## Questions & Answers

**Q: Is this a product that has to be used at every oil change? How does it perform with Mobil 1 EP 5/30?**
A: I use only mobil 1 products. I use this in two deisel engines one dodge one Mercedes, and gasoline Ferrari 360.  No issues at all make them all run quieter and smoother.

**Q: How long should you leave it in your oil before changing the oil?**
A: Sorry for the delay. Cera Tec is going to work in the friction system for 30.000 miles . But you are going to change the oil as always you do. Before use Cera Tec,use a Liqui Moly Valve Clean in one full fuel tank, then change the oil and after use Cera Tec.

**Q: I already used one can but my audi S5 3l takes 6.2l of engine oil. I ordered another can, should I pour it all in? Are there any issues with overfill?**
A: From the product packaging Application: Minimum oil filling of 3 liters [3.17 U.S. QT] is required for optimum product performance… Will treat 5 liters [5.28 U.S QT] of oil [6 % of total oil quantity] Continue to maintain oil change intervals as prescribed.

**Q: How this product will perform with a high mileage engine that is worn and consumes oil? Is there a possibility that oil consumption will be reduced?**
A: That’s not true. There is a differance between high mileage and non high mileage oil. The difference is the additive package. High mileage oils have higher levels of moly and zddp phosphorus and other anti wear chemicals. At least they should. The ones I’ve compared do have higher levels. They also contain seal conditioners. When rubber seals age they can become cracked and brittle. High mileage oil contains conditioners for this. Now how well all of this actually works is up for debate but they do contain different additive packages. The thing that makes an engine oil is the base oil used and the additive package. Additive packages are generally around the same but they do differ by oil brand. Generally you can’t go wrong with Mobil 1, redline, Eneos, Castrol synthetic, royal purple, Quaker state synthetic, Valvoline synthetic, Amazon full synthetic, Napa good synthetic, or basically any synthetic oil. I have a Nissan and I use Eneos 5w30 because it’s a Japanese oil made in Japan for Japanese engines. Can it be used with any engine that requires 5w30? Of course it can. It’s just a personal preference and I know that they use a robust additive package with average or better percentages of all the additives.
