The product comes without the appropriate funnel for pouring into the reservoir. Be careful, take the smaller quantity!

The product is excellent. After continuous regenerations in the DPF, especially in city conditions, and immediately after using it (half a bottle in a full tank), the car performs perfectly with the engine functioning like new. I recommend it to everyone who drives long distances in the city, which makes the DPF regeneration process difficult. I use it in 3 cars with TDI engines (1.6 & 2.0).

It is the same as the small packaging.
At a much better price, of course.
It does a great job, I can tell from lower consumption and less fuel returns in the oil.
