Genial what makes this stuff

Had 3 doses ordered and I have times a can when refueling reingetan. The motor v5 2,3L 150PS / 110KW had unwound until then about 220tkm and ran out of true above all in the state of gas. I could not notice any improvement, but then. Was probably due to the short stick (3-5km) which I went to work every day. OK still had 2 and one of them I've done purely on a 250km round trip with. Ingeniously, the engine is quieter, smoother and comes from low speeds in the 3rd and 4th gear much easier from under out so that a turn in 3rd gear is no longer a problem. But one point of criticism I would like to get rid of it and relating to the packaging: It is not possible, the can 100% to empty it always remains a residual amount in a can which is then disposed of because the manufacturer has a different solution be found for environmental reasons.
