I put it in a 2007 Suzuki SX-4.
Excellent, just like the 10w40 I have tried.
Simply, the 5w40 performs better when the engine is cold.
Silent engine, and responsiveness!
Better than the Motul 8100 in every way.

On a Citroen C4 1.4 petrol 2007 with 182,000km
I used to use oil from the dealership and had a steady consumption of 80ml-100ml per 1,000km
Since I started using this oil and drove it for a few days and after a good run, the consumption per 1,000km is zero, the engine runs better and at high revs it doesn't "cough" but "sings". I highly recommend it, especially for engines with high mileage

First kilometers... I liked the engine and improved cold starts and performance. In my opinion, one of the top choices in 10w 40. I am waiting to see how the molygen works in the long term... Testimony from an acquaintance with an engine issue where there was noise after 3 months of use—the sound disappeared.

I got the 10W 40. Very good oil, I put it in a Peugeot 106 rally 1,600cc. With all the other oils, the valve covers made a bit of noise, but as soon as I switched to this one, it stopped, and now I have it in for 8,000 kilometers.

I used the equivalent Liqui Moly in 10W-40 all summer successfully in an SX4 1.6LT petrol and put this 5W-40 for the winter. It doesn't burn any oil at all, the engine is quieter and slightly more economical than other oils. It suits this car better than many others I have tried.

The engine's behavior changed from the very first moment. The noise was reduced and I also notice differences in the oil temperatures.

Usage in VAG group cars mainly, of family and friends, over the last 20 years with various gasoline engines, atmospheric and turbo. Everyone is very satisfied with the product. You understand various aspects of the engine's operation.

10W30 in Grand Vitara with J20A with 200,000. The manufacturer recommends 5w30 / 10w30 / 10w40. For several years the engine worked with Motul 6100 10w40 which it burned (probably leaks from seals). Changes at 5000 since after 5k it burned much faster. I decided to try something more quality with much better specs and newer specifications. After a lot of research, I ended up with Molygen 10w30. I was very satisfied with the engine's operation and performance, but unfortunately it burns much faster than motul 6100. A very big difference.

Although usually in the first change from brand to brand an increased oil consumption may be observed, I believe that this large difference in consumption cannot be covered if I continue to use it.

I am thinking of trying the 10w40 molygen even though its specification is SL and the specs are slightly better than motul 6100

I have been using it in my Seat Ibiza FR 1.2 (2014) (5w-40) consistently for over 5 years with oil changes every 10,000 km, and I have never seen it burn oil even though it has a VW engine. While I have used oils from other brands (without additives), I always end up coming back to this one because whenever I tried a different oil, I would hear the engine sounding like a tractor (even when I tried Liqui Moly Top Tec from the same brand). This specific oil already contains an additive for friction, so there is no need to add anything extra during oil changes. The truth is that it has a slightly higher price, but it delivers on its promises, so I choose it consistently.
I have also used it in a Mitsubishi Space Star/Mirage, again the 5w-40, and it seems to work just as effectively.

Since I started using this, not only does it work better, but it doesn't burn any oil drops ..
... the highest quality oils I have ever used

As for my own cars, they did not work properly (Yaris 2007) 5-30 (Elantra 2001 10-40). I have been satisfied with cheaper options. So, I believe that you pay for the marketing and not the quality.

Excellent oil, the best of the best, I have been using it for the last 5 years and I don't change it. The tappets were making noise when starting with cold, and when I first put this oil and since then, all the noises stopped. There is no smoother and quieter engine operation. The best choice for anyone who wants an engine for a lifetime!

audi a4 1.6 of 2000 with a total of 329,600 kilometers. I bought it because I read good reviews and the brand is quite powerful and has won various awards in Europe. Overall, the car is consuming a lot of fuel and I thought of giving it something extra to see if I can fix it. Which didn't happen, exactly the opposite until the scheduled change, I estimate that I will use a total of 4 liters.. Until today, I have used 2 liters and I still have the same amount of kilometers left.. I thought of burning whatever needs to be burned to clean it and then switch to a more economical option like Castrol GTX, which is better for old engines and half the price.

Truly the best thing I have put in my car.
Opel Corsa D 2009, I saw a big difference, guarantee!!!

For now, it's working fine. The engine hasn't consumed any oil. Of course, we'll see in the future how good it really is. The price is a bit steep, to be honest, and I'm not so sure if the price difference reflects in the performance and engine protection.

Update 3/12/2023: I continue using it. It's a Nissan Primera 1600, year 1997, with around 290,000 kilometers. The car doesn't burn a drop, so it's in excellent condition.

Excellent oil. It was put in a Toyota Auris and I can say that it works more quietly, especially at high speeds.

Update

After 10,000 kilometers of use and as the time for an oil change approached, I come back to say that during this whole period, the car has changed a lot for the better and of course, I will only use this specific oil again. Also, for those who claim that it is expensive, I would say that it is preferable to drink 3 fewer coffees a year than to go for something cheaper.

It will probably be good.
However, in a Mazda 2, when it's cold, you can hear the valves until the oil rises.

Excellent oil, quiet engine operation and performance. Putting it in, you feel confident. TOYOTA Auris 1.33 16V.

Very satisfied. The oil was put in a Micra K12 1.2 with 180,000 km. Whatever oil I had put before, the car was making noise after 3500 rpm. The soundproofing is also terrible and it was chaos.
As soon as the 5w40 Molygen was put in, it became much more refined. I also feel that it pulls better without any drama. My ears calmed down during the trip.
The car didn't lose any oil before, so I can't help if it burns less or more than before.
I bought it from a physical store that is an official importer in Greece and not from Skroutz.
The packaging shows that it is 100% genuine and I checked it with LIqui Moly by sending them an email with photos.
Overall, I am quite satisfied and I won't change it.
The only negative is that due to its color, it hasn't received any manufacturer approval and it is recommended, not approved.
So, in case you have a new car under warranty, get something that is approved for the specification given by the manufacturer to have peace of mind.

Entered in a Daihatsu Coure after an engine flush with a corresponding product from the same company. From the first moment, one can understand that it is of high quality. The engine purrs and is not even audible at high revs. Easy morning start, the valves are barely audible. I have driven 3500 kilometers and it still hasn't burned any oil... usually, every 10,000 kilometers when I change it, it burns about 500 ml. I will come back for an update during the next oil change

I put it in a 2005 Hyundai H1 with 300,000 kilometers. I always used oils that cost 12-13 euros because it was biting. The engine always made a noise at the start, and I thought that's how it is. I first did a flush with Liqui Moly's Flush and then I put in the Molygen. Honestly, I was amazed. The engine is incredibly quiet and at high RPMs, it sounds completely sweet. I hope the oil consumption will also change, and I will use them forever.

fast service, very good oil and price.
November 2022: From the first use in the 2004 Corolla 1.6, the engine runs perfectly, with lower consumption! I have done changes at 10,000 and 11,000 km and the old oil comes out like new! This time I will keep it over 12,000 km to see in what condition it will be! 2025: and at the change of 12,500 km the oil came out as if it was new!

I use it in a 1999 Corolla with 290,000km for a year now, with viscosity 10/40. I push the car quite hard, especially during trips with heavy loads, etc. The oil is flawless!!! It doesn't burn a drop, the spark plugs are clean when changed, and in the morning, with half a throttle, it picks up speed smoothly and works quietly and smoothly like a warm engine. I change it every 7,500 miles and the oil still has life left in it. Very trustworthy oil

Excellent product at a very good price!!!
Very polite staff, prompt service.
I will definitely shop again!!!!

I use them in a 2002 Volvo V40 1.9d with over 200,000 km.
The first thing that impressed me from the first time the engine started is how smoothly it still runs even in low temperatures (-10).
It doesn't burn a drop, and I will definitely choose it again
