Liqui Moly 20002 Cera Tec Friction Modifier (300 ml)

awesome product. I have used this in my Renault Duster 110ps diesel car at 85k with fresh engine oil shell helix ultra. Car is running like new and feels like I am driving a petrol car. Engine noise has reduced significantly.

Best n fantastic product.I didn't expect to that's working.My car is petrol used in that's working best and effectively.After using this product my car running smoothly, less vibration and noise.

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/S. All vibrations and noise are reduced surprisingly.I got this at Rs. 1717Pros:1. Reduction in engine noise2. Reduction in engine vibration3. Car cold start gets smooth4. The car feels like butter smooth even running at more than 100 km/sCons: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 buyingPersonal Recommendation:I tried this in my car as I want to try this, as 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.

Best n fantastic product.I didn't expect to that's working.My car is petrol with cng used in that's working best and effectively.After using this product my car running smoothly, less vibration and noise.

Very good and effective. My car engine has become more smooth now.

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 changed1) Reduced noise from engine bay to cabin2) slight improvement in mileage (10%) full tank to full tank method.3) smoothness in engine during idle and on the run while acceleration/pick upNow 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 itemsLiqui Moly Engine FlushCeratec 2000Shell 5W30Post 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

Not so noticeable changes very minor which may be due to new oil better investing in a good quality fully synthetic oil.***update: After covering 700kms I found that --1. the mechanical sound from my engine is reduced to great extent.2. heating is way more controlled than before3.slight improvement in fuel economy(very minor)4. smoothness increased with very minor pickup and torque increase.would update again for the long lasting effect to be true or not post oil change.

Giving this review after 3 months of use in a 2018 Honda City Diesel with 1 lakh km driven. Mileage increased by 3–4 km/l, engine noise reduced, and pickup improved.
