There are indeed a variety of different engine oils, various Viskostäten ... because it's not easy to keep track. Sometimes the discussions in the relevant fora, such as religious wars seem to. I made me even bother many discussions (mostly Motor-Talk.de) to read and then I came for me to the decision, only to drive a fully synthetic engine oil. The fully synthetic oil 5W-40 Liqui Moly is known there as always a very good oil, I have only had the best experiences with it themselves. Deposits in the engine can not be detected. My workshop fills this oil at my request one, the canister should I bring, at Amazon, the oil is significantly cheaper than the hardware store or auto parts trade.
