I was worried before using this product so did my research on it, people left good reviews so I went a head and mix it with my castrol 5w 30 LL, i used liqui moly engine flush, drain dirty oil, changed oil filter and poor it in my engine. After driving couple of 100 miles I noticed a massive difference in speed, engine noise, miles per gallon increased and engine was running very smooth. Loving this product and please go a head and test it yourself.

This stuff starts to work approximately driving the car about 400 miles , you feel more lighter engine noises , and improved acceleration . Car used in ( BMW 320d , 2012 M sports ) Manual gearbox . Mileage now 245k miles on the clock , using it since it was 140k and using it in every third oil change . I always put with new engine oil change . Oil I use is BMW Original 5w30 ll04 .

High Tech additive. Used on my private fleet: Volvo S70 2.5l gasoline engine, KIA Sorento 2.2Crdi and LDV Maxus Motorhome conversion. Results are very good! Reduced noise, better performance and torque. Not much on saving fuel.

The effect began to be seen after the first full of diesel (65 Lt), the performances increased much beyond expectations. I am very satisfied, as proof I bought 2 more units to have in the garage to use next time. I recommend them with all confidence.
I have used this in my taxi (Seat Leon 1.6 TDI) since I ourchased it 2nd hand and 3 yrs old. I always change the oil when the dashboard light advises and have always added ceratec. At over 100,000 miles, the car is running as smooth as it did at 60,000. I'll continue to use the Ceratec every oil change to get the best longevity from the engine.
Used in two vehicles, both "felt" smoother and demonstrated a 0.2L/100km improvement in fuel economy.Sent off an oil sample for one vehicle, wear numbers were good - and analysis showed heaps of Boron and Molybdenum (the ingredients of this product)Can't comment on longevity (i.e if the product remains in the engine) - Suggest using every other oil change and use Mos2 in between (if you really want to).Downside - Very expensive - Perhaps smarter to put the money toward better oil! 5/5 regardless of price.
My jury is still out on this product!! I have read quite alot and MOST feedback is very positive so I intend to make my own trials. This product is added to the engine oil and then forms a kind of "cover" within the engine and should thus reduce friction and thus improve performance and also fuel consumption. I cannot use this product in my motorcycle engines cos it is not suitable for wet clutches, so I will try it in my car engines. Watch this space!!!!
...I read about it in the Porsche Cayenne forum that it has very good reviews but I was a bit sceptical. I bought it and mixed is as described into the oil. I would recommend a suitable container. I have not used it in my Cayenne but I will as soon as the next service is due. I used in instead in my race car. I have to say that I had some problems with idling. It wouldnt idle for too long before the engine Stopps. Now after a couple of minutes the engine sounded quieter and was idling for much longer. Ill have a booked a dyno next week but the difference was noticeable within minutes.
I have used ceratec in my old car engine for a year now. My advise is to use a third of a can to start with. Slowly over the next month add the rest to the engine weekly with normal driving till the engine run at highest working temperature. This Will ensure that all wearing surfaces will get an even coat of ceramic where it is needed most on high pressure areas like bearings, combustion chambers and pistons. This also ensures that you don't get a mud slurry clinging to the internal surface of your engine, potentially trapping heat. Next for manuals only, replace your gearbox oil with a third of one new bottle of ceratec and do the same procedure for the gearbox as you did for the engine, as ceratec works on manual shift boxes as well with amazing savings in fuel ... MoreI have used ceratec in my old car engine for a year now.

You will notice smoother gear shifts and better drivability if you follow the correct procedure as stated in this review. Good luck and enjoy this truly amazing product that works!
This stuff is brilliant, it genuinely works and gives noticable results pretty quickly. I use it with every oil change in my 2012 BMW 328i, the car seems to love it. It feels much more smooth, the engine is less rough at idle and on cold-starts it sounds much healthier. For the best results, flush the engine before draining the old oil, and use premium branded oil like Fuchs/Castrol or similar, with a K&N high-flow oil filter and finally the CeraTec. Honestly, it breathes new life into ANY car. Repeat the process with every oil change.
