hello, have to make my own oil change (well oil drips out just until tomorrow evening). so now no question about the oil. which should I use? was today at the POLO shop which picked out the following:http://www.polo-motorrad.de/…/Productdetail.productdetails.0.html Racing Dynamic Viscoil 10W-40 High-quality light running oil. specially adapted to the demands of high-turning motorcycle engines. Reduces friction for optimal engine performance, offers optimal wear protection. API CE/SG. Order no. 55010100020 should be a mineral. I’m only a little skeptical because it cost only 23 euro. can I use the oil without thinking? greetings
