In the meantime I have about 21,000 km on the speedo and yesterday on the occasion of my 4th (in words: fourth!) refilled liter of oil the following funny event at the gas station: Despite the beloved habit, I had forgotten again which oil types I had to pour in the Cayenne S and krame the manual from the glove compartment when a quite familiar noise appears next to me. The colleague parked his Cayenne Turbo at the pump next to me and runs straight away. in. On the oil shelf we meet again, he had the much routined handle to the 5W40. With the parallel synchronous filling and technical simples it turned out also why. I already thought my good 5000 km/litre was quite greedy. He reported with his turbo only of about 3000. Is the oil consumption with others also so high? With the comparable BMW engine this is much less! What is this?
