LiquiMoly 3721 Engine Oil Additive

The way I use it: AFTER an oil change, with motor warm, shake the hell out of it and pour it in. IMMEDIATELY start driving. Somewhere about 10-12 miles, you will hear the difference, and your engine will continue to get smoother. Added this to a '20 Honda Civic that I could not drive in Sport mode. Just nasty noises! Now, i use S-mode on the on ramp, and I sometimes forget to take it out. I was five miles down the road the other day, and realized I was still in a lower gear, that's how quiet. Bimmers, Miatas, Tundras - they all love it. Smoooooth is number one result. Umm ... I don't see any milage gains bc it makes driving more Fun :))

Purchase price.was great. Product really worked for me. I did notice a slight improvement in fuel efficiency and power. Most of all it did aid in engine sound. Do read the pros and cons on the product before using it. Reviews on the product are very informative but do read up on the pros and cons of the product, especially do notice the date of production on item. This is very important.

This is good stuff! My engine got a little bit more quiet, and noticeably smoother, and I got a little better gas mileage on highway trips about 2 1/4 miles per gallon more. Just so you know, it’s in a 2006 Mercedes-Benz C230 sport with 206,000 miles. I had changed the oil about 2500 miles ago with liquid Moly 0 W-40, and I just poured it in. No lie you can actually hear it circulate and quiet down the engine and it’s really cool to hear.

I previously used the Ceratec on a friend's Honda Cr-V. Before using Ceratec, I wanted to start with a clean slate, so I added Liqui Moly engine flush into the engine, ran the car on idle for 15 min, then drained oil and replaced the filter. The drained oil was super dark, so to make sure I got all the gunk out, again, I refilled the oil with a cheaper oil of the same grade, replaced the filter, let it idle for about ten minutes, and drained it again. This time, although it wasn't as dark as the first flush, you could see the oil wasn't as new as it was when I poured it in10 minutes prior, so I was glad I did the second flush. So now the motor was ready for the good quality fresh oil, new filter and Ceratec. To make sure there was no fall out/accumulation of Ceratec inside engine cavities and passages, I took out enough oil from the new jug, then added the Ceratec inside the jug, turned the jug upside down a few times, this way it would be premixed before being poured into the engine. After running the car for a while, we noticed that, that annoying lifter noise had almost disappeared, it had become very faint, which is a big plus in my book. I will be repeating this same process in my E36 M3, as these engines tend to have lifter and vanos noises as well. I will be updating my review if I don't notice any difference in the M3.

I trust ceratec brand for keeping my metal parts inside my engine area lubricated. From my understanding, it bonds to the metal so it doesn't dry out and you don't want to start an engine with dry metal because most of the oil falls down to the oil pan. It came in a sealed plastic wrapped package which I like so it's not tampered with.

Let's be honest, any review of this is a bit subjective. What I can say is I've found that each engine I've put this in runs a bit quieter. Thus far I've put it in a 2024 Toyota Rav4 Prime, a 2024 Ford Ranger Raptor, a 2019 Mercedes S63 AMG, and a 2021 Ford F150 5.0L. I put it in with a fresh oil change and in pretty much every case, it seemed to provide some benefit or peace of mind. I can say I've had no negative consequences, but the most notable I've found is the quieter startup sound when the engine is cold. Will it make the engine last longer? I have no idea. Does it help MPG? I have not noticed much of a difference to be honest.

Update 1: 3K miles on Honda (41K mileage) - its better than the sound without ceratec in it. For a given car, less sound = less wear R171 - over 2000 miles, great mileage boost. Got back to the manufacturer suggested MPG rating of 24 MPG on highway, a boost from around 19MPG with ceratec and fuel injector cleaner together. Update after 500miles on Honda CRV: Not worried about the fuel efficiency, that's not the purpose of buying this. But fuel efficiency is an indicator of less friction and less wear. Definitely getting at least 1MPG higher, so at least that much frictional force is now avoided in the engine components. So, now I expect the Honda CRV 2017, known for oil dilution to last at least 100K miles. (40K now and 60K more to go). So, planning to use this with every oil change but add only 50ml for 4 gallon oil, to be safe. Pending Update on 3L naturally aspired R171. _____ Original Review: I got that notorious Honda CR-V 2017 1.5L Turbo, known for massive dilution with it GDI. Will update the review with results if that's affecting, if there is anyone interested to know (give me a 👍 so I know). I should know once I hit 2000miles, the Engine generally becomes ticky. Let me see how that helps. Fill oil to a min level, then added this, ran engine for few mins, topped up oil to get the level close to Max. For now, as soon as I added this with new oil, of course there is a reduction in noise and less ticking. But I don't know yet if that's due to new oil or Ceratec magic. Will update after I clock 2k miles. On my SLK300, 3L V6 naturally aspired engine, there is no noticeable change. I am expecting to see feedback via 0.5MPG increase, probably I should wait for 500miles at least, from what I read from the manufacturer. The bottles had some dings on them, probably not due to Amazon logistics because the paper cover was intact. No issues though.

Why did you pick this product vs others?: Can tell an immediate difference. Engine idle is smooth. I put this in at every oil change !

Le produit parle de lui-même excellent pour bmw diesel

جيد

Citroen C1 el motor va mucho más suave se nota al circular, el consumo ha bajado un poco, creo que merece la pena usar este aditivo, se lo he echado al coche por comentarios de la gente, Ceratec lleva muchos años en mercado y te da seguridad.

This is NOT substitute for regular oil changes. However when a number of things are done simultaneously, this makes sense: 1.Services as per recommended. Actually recommend servicing the car 500km before it is due.Regular engine oil changes help 2.Keep spark plugs and injectors clean by physically maintenance of gaps and throttle body cleaners In conjunction with the above, the Cera Tec works by reducing friction inside the cylinder by coating with a slippery boron oxide modifier. This means less friction, less heat ,less sound and a smoother engine. Ideal for cars having crossed 60000km and above. My Hyundai Sonata 2.4 GDI MT runs butter smooth now

It does what it’s supposed to do. Expensive
