The Opel Corsa C 220k engine sounds much better. It doesn't struggle as much. It didn't bother me during the summer with temperatures in the 40s, but it's great in the winter. I also use other products from the company because the car is old and I see a difference. With the oil change, I also added the engine cleaner and the fresh clean oil turned black.

It is a good lubricant, recommended by 2 mechanics for Golf 4 and Corsa D. The price is good and the lubricant is genuine. I recommend it for engines 10 years old and older, like the ones we have, and why not for all cars that take these numbers.

I had higher expectations for this specific product due to the company, I will return to Motul 10w40 4100, which is much better.

I put it in an ALFA 147 and it purrs. (July 2023)

Although it is a nice oil, you need to constantly check the oil level. Attention!

The engine works quieter than others in the same price range, so it achieves better lubrication at least in mine (Alfa Romeo 147).
As for the negatives, after 4,000 kilometers, the impressive anti-friction properties of the lubricant are noticeably diminished, so I change them approximately in this period...

Cheap and good oil. Personally, it suited well in my car that consumes oil at the same rate it drinks my blood

So far, the engine has calmed down very well, the pistons are not heard. I will put it again. Alpha Romeo 147.

In Mazda 3 2006 with 210,000 km, which I have done with Motul 4100 Turbolight oils, I decided to try them for a change since the company is very good and their price is quite economical. The engine runs without unnecessary noise and without any additional tremor. I haven't noticed any consumption due to exhaust fumes. Compared to previous oils, I didn't see any noticeable difference. It is also a decent oil.

I changed the oil with this specific one in my BMW E36 318 with 290+ kilometers because I had a problem with the tappets that were "rattling" during startup when it was cold and after a few kilometers at idle.... The noise literally DISAPPEARED and I have noticed that the engine now runs smoother and more steadily both when it is cold and after a long journey. I never had a problem with oil burning, so I don't know if it burns faster than other oils. I will definitely use it again!!!

First time changing oils with this specific one on my MB W168 after many years of using exclusively MB oil. No comparison! The engine noise decreased and its operation became smoother!

The oil is good. You understand it immediately. The engine's sound changes. It doesn't burn easily and seems to do what it promises.

This specific oil has recently been improved to meet API SN, MB 229.3, and RN 0710 specifications, and for its price, it is a great value for money. With the addition of mos2, it becomes excellent!

Very good 10w40, it does not burn easily due to its higher flash point compared to others and has very good cleaning properties. The car had poor maintenance and the engine was very dirty from the previous owner who serviced it, so it remembered. After 2 years and 6 oil changes every 7000km (20-22 thousand per year due to work), all moving parts had changed color.. It is good for the oil to darken! It cleans the engine!

Very good oil, I classify this one among the best semi-synthetic 10/40 oils in the same category. It delivers everything it promises, provides excellent lubrication, does not easily burn, and creates a very durable film on the engine parts. You can tell from the moment you start the car. Despite being under pressure all summer, I changed the oil at 8000 miles and it came out black, but the car was still running smoothly in the heat of Athens, and the oil came out in a normal quantity. Those who are familiar with the conditions in Athens will understand. The oil is excellent

Very good oil. The engine runs smoother, immediate cold start, very good cleaning properties (when an old car was opened for general repair, the engine was literally without any combustion residues, shiny metal), SOS... flash point 226 degrees higher than other brands (so it doesn't burn easily) and there are no adulterated batches like Castrol, Motul, Mobil... from Turkey, Bulgaria!!

Good oil seems.. Just after 6000 km it was quite blackened.. I don't know of course if it's due to the car or the quality of the oil. I will also try the motul synergy 6100+ and I will come back !!!
