LIQUI MOLY Oil Additive Cera Tec 20002 Ceramic Wear & Tear Protection for Petrol & Diesel Engines Smoother Engine Performance, Less Friction & Lower Fuel Consumption 300 ml

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.

So bought this for my new Mazda 3 Turbos' first oil change. I was originally going to use Liqui Moly MoS2, due to the OE Mazda oil using a very high Moly PPM (800ish) formula and not having easy access to a similarly formulated oil. After doing some more reading i decided to use Ceratec instead, mostly because it doesn't make the oil look super dark (for warranty purposes, If for some reason i do have a problem with the engin i don't want the dealer saying I just didn't change my oil). So initial results are awesome, the valve noise is pretty much gone. And the engin just feels smoother, and sounds like is not even trying when reving it out. With that success I bought another one for my girlfriends non turbo CX30 when i changed her oil. Her engine has always been just a little noisier than my old non turbo mazda 3, and my new Turbo model. I've used the same oil in both (Pennzoil Ultra Platinum 0w20 or 5w30 in the turbo). It had the normal lifter noise, but it always sounded raspy when accelerating hard, like it was really at the edge when floored. So as a before and after test I changed the oil fist with NO Ceratec, engin sounded happier, ran a little smoother, but basically the same as before, Normal stuff after an oil change. So I added the Ceratec, literally you could hear the lifter noise melt away as it mixed with the oil, I was in my garage so the effect was even more stark. The engine also idled smoother, to the point if you were in the car, you wouldn't know it was on without the engine RPM readout. So i took it for a test drive down the road and stepped on it after getting it up to Temp. The raspiness was completely gone, it sounded like it was happy as a clam reving right up to redline. This wasn't a "i think it might be better" differance, it was a night and day difference, a wow that impressive difference. As for fuel consumption reduction claims, i don't know yet, from what i read you need to dive it 300-400 miles to get a valid result. I only have 150ish on mine and 75 on hers. First impressions were really positive, highly recommend to anyone wanting to keep a car for a really long time. Only downside is the price, this stuff is really expensive... but i look at it like this, $600 over the life if the vehicle if you keep it to 150K miles, with 6k oil change intervals is pretty cheap insurance. compared to an engine rebuild.

UPDATE 3-22-17: Ceratec is, if one can believe it, gotten even smoother in my wife's 2011 Outback 3.6R. Cooling fans run noticeably less when AC is not on after a hot drive. Cold startup on a 40 degree F morning sounded just like a hot start on an 80 degree day. MPG gain has remained. Wife comments that the engine seems to rev more easily. Also applied to my 1999 Porsche 911 Carrera Cabriolet's 3.4 liter flat 6. Instant improvement in smoothness both at idle and when revving. Actually has made it more difficult to intentionally stall the car on my steep driveway. Engine coolant temps also read slightly lower (just slightly). I used one bottle for the 10 quarts of oil in the engine....at HALF the treat rate, I'm seeing a marked improvement. Next oil change I will transition from M1 0w-40 to Castrol 0w-40 (a better oil, with a slightly higher KV) and will add another full bottle of Ceratec and report back. Only approx 600 miles on this Ceratec treatment and the improvements are growing, as in the 2011 Outback. Seems like every drive it gets ever-so-slightly smoother....especially when cold. ******************************************************************************************************** This added noticeable smoothness and .5 mpg to my 2011 Subaru Ourback 3.6R Limited. The engine was already smooth with Pennzoil Platinum 5w-30, but this increased that smoothness at all RPMs. The engine is physically quieter at idle, especially with the sound deadening engine cover removed. This was an immediate difference. I then took the vehicle on a 300 mile round trip on the highway and the improvement has remained. The engine was already very quiet from inside the car, but it has gotten even quieter. It sounds very much like a turbine now and it is very pleasing. Gaining a solid .5 MPG is also excellent. This is outstanding insurance against cold-start wear, even when it's NOT actually cold outside for those high pressure contact areas in the engine crank journal bearings, cam lobes, lifter contact areas, etc.

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 Amazon, 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.

This stuff speaks for itself. It has a good reputation and that’s pretty much all I can go by. I have had no issues with it. It will make your oil look milky, just be aware of that.

My car does run smoother but the noise is still there

I’ve been using Liqui Moly Cera Tec in my Audi A6 3.0T, and the results have been impressive. This high-tech additive contains ceramic microparticles that form a protective layer on metal engine parts, significantly reducing wear and friction. ✅ Key benefits: Improves engine smoothness and reduces annoying noises. Extends engine life by minimizing wear. Compatible with all types of oils and engines (gasoline and diesel). Enhances overall efficiency and performance. It’s easy to use—just add it to the engine oil during an oil change or top-up. Overall, Cera Tec is a smart investment to protect your engine and boost performance, especially for high-mileage or demanding driving conditions.

Very cheap compared to buying it locally, here in my country. Used the Ceratec with the Leuchtlauf High Tech oil. 143K miles on my 2.5 mk6 Jetta. It started to make some tappet/lifters noise, very minimal but it was there. As soon as I started the engine, and about 30 minutes in , I could clearly hear the difference. How I heard the difference? With the hood closed now I can barely hear the engine, unless I put my ear close to the grille. Now I only hear the working injectors. Totally recommended. Can’t speak about gas consumption, I’ll have to drive 500-1000 miles to speak confidently. Recommended for giving older engines a longer lifespan.
