I put it for the first time a few days ago in the major service on a 2003 Corolla that consumes a little oil, about 500-800ml every 5000 km. From the first day, the engine literally works silently, while in the past, when I would start the car in either summer or winter, the engine would sound like rattling. As for whether it burns it, I still can't know, it's early, it will show with time.

Some engines burn it like water........ on the contrary, Castrol gtx and motul 4100 perform much better after tests

I had put it 3 years ago in a VTS 16v saxo, raised as much as possible with the factory internals.
Often I would hit the rev limiter at 8,000 RPM.
This car had tried several oils, I would change them every 4 to 5 thousand kilometers.

The specific oils have the advantage that they were among the few I have tried and they did not burn (and I am talking about a wide range of RPMs) and I have the impression that they cleaned my engine without saying it with certainty.

On the downside, the car made a bad noise and when it was hot after taking a lot of beating, the oils are also black and it is much more difficult for me to understand their condition after the change.

I have been using it for 4 years in a 15-year-old car with regular oil changes, as the manufacturer recommends. It contains molybdenum to create a "film" in the engine. The engine runs quietly! It is suitable for cars with high mileage. Two mechanics asked me why it is black compared to what they knew, it's because of the molybdenum! I can't find anything negative, but I am already looking for the next best product. As an option, it is not more expensive than oils from other manufacturers, but there is nothing similar in my knowledge on the market. I recommend it!

Very good oil, I had it in my car for about 10,000 km for a year and it burned very few ml. Don't let the color bother you, it's dark gray and doesn't resemble the other oils we know from the market. I highly recommend it.
