Seriously?! Rating 4.9?!
I don't know why I was so unlucky... in Russia I refuel exclusively at Gazpromneft. I refueled in Brest and everything was fine. After this "excellent refueling with a rating of 4.9", the car just stopped driving!!! The receipt also caught fire. Thanks for the Mercedes 40k repair. I wish you to continue driving Chinese cars and selling the same bad gasoline.
Gazprom's diesel fuel is cleaner, even without additives, and the engine is quieter and more powerful. These are subjective feelings, but this is also a review, not an article in a scientific journal.
