It went into a Toyota Rav4 2006 2.0 with a 1az-fe engine at 187,000km. I noticed a strange noise at idle (it sounded like diesel from the front seats) that I had heard before with low-quality oils. No significant difference in consumption.

Quiet the engine kids what can we say. I asked the team with the Fiat Punto (199 Diesel 1.3 multijet myself), some "active" members recommended it to me and they were right. I recommend it WITHOUT HESITATION.

Toyota Rav4 2.0 D4D with 250,000 km. The engine sound has changed and I think it sounds quieter than before... although I'm not 100% sure. I haven't driven many kilometers with this oil yet, it's the first time I've used it. Another thing I notice is that it emits quite a bit of black smoke compared to before (I want to believe that it's cleaning).

I put it in a TJET engine with a larger turbo and a tune. Smooth engine operation, you don't realize it's working. Change every 10,000km.
Even after 100-200km, the oil turns black. This means that the oil is working and doing what it promises. Some people get confused and think that if it turns blonde, it means it's good oil. BIG MISTAKE.

Instead of having every mechanic put the oils they sell, it's better to buy the manufacturer's oil and have them charge you for the change.
There is a big difference in noise and engine response when used in a Fiat Punto with 180K kilometers.

In general, good oil. I expected something more due to its price and the comments I had read on the internet. I switched to this from the old LM 5w40 molygen, which ultimately were much better at almost the same price

Since I rebuilt the engine (AUDI A3 1.6 '98), I change the oil every 15000 km instead of 7500 km and barely 300ml have been lost.
150000 km since I first used them.
Update 2022
190000 km and the engine still doesn't consume oil

Alfa Romeo MiTo QV! The engine's tone has changed to an incredible extent! It started working smoother, sounding less at idle, and I think it revs better and works more effortlessly... Now, if it will also have fuel economy on long trips as a result of all the above, we are talking about a significant change compared to the SELENIA that the manufacturer recommends and I used until now... I should note that the engine has 180,000 km on its back and it is the first time that "foreign" oil is being used outside of the dealership!! I highly recommend it as the best choice!

The oil at 15000km, 10000km, 7000km should come out BLACK!!! If it comes out blonde, something is not right...

In Opel Astra H with Z16XER engine, I get an extra 70km per fill-up compared to Opel's low-quality oil. I don't know about other cars, but mine runs smoother with this oil. Of course, it costs around 50 euros compared to GM's 20 euros, but you get what you pay for. In the previous oil change, I left it in for 15,000km and when it came out of the crankcase, it was still blond compared to GM's oil which I changed every 10,000km at most and it came out pitch black. This means something. Give it a try.

Until now, I have been using Castrol Edge 5w30. Now, I tried this one to see if it doesn't burn it. After a year of using it, the consumption of oil has significantly decreased

One of the top and reliable oils at the moment with absolute criteria for performance and reliability. Personally, I use it in a Honda Civic Type-R EP3 with 5-40W for over 75,000 km. Last week, we opened the cap for valve adjustment and the mechanic was amazed by the image he saw, from an engine that has done 145,000 km. It was ready for exhibition without any traces of residue, color like new, in short, a mirror! Very low oil consumption, 300-400g in 7,500 km, and hard driving in its special breed 2-3 times a month, a special difficult one with continuous uphill and downhill in 2nd gear with 7-8,000 rpm, 3rd gear the same, and difficult and final ones in the mountain in downhill up to 250 km/h. And on the way back, one stop before the taverns, you hear the engine idling perfectly. Tough oil!! What else do you want?
