Hi, I recently had the fun of testing the maximum range with a tank filling. Extremely economical driving, no short distances, no high motorway speed. Result was 960km and a consumption of 7.2l after BC (7.26l after tank receipt). I had super95. With the Ergeiz, once to crack the 1000km I then filled the V-Power, in the hope to push the consumption still around the missing 0.2l. That the lower consumption does not weigh up the extra price, was already clear to me, but since the engine is actually designed for Super+, I thought it should bring it a little bit. However, after the first 200km the BC already showed an average, which was 0.5l above that of the previous tank filling. Can this be that the engine with Super+ consumes more? Ride otherwise for 9 months only super. The only other explanation, would be the colder weather, i.e. the engine gets warm later, the air pressure goes down perhaps by 0.05bar. But then the air speed has to do the same, but then the radio has to do the same thing.
