Hello, since 40000 kilometers I use the 0W-30 oil. My dealer had also recommended this wg. fuel saving, motor-friendly etc. . Now there are many different opinions about the 0W-30 (like water, too thin, motor-damaging). Since my driving performance is 30000km a year I want to have the engine long enough of course 🙂 What kind of oil do you have? What do you say about the 0W-30 ?
