Hallo zusammen :-)
Hab da ein interessanten Beitrag entdeckt, da kommt man als Endkunde schon ins grübeln
Aber es ist ja immer das gleiche, KOHLE regiert die Welt

Good evening CH-Cruiser!

I worked with engines, (generators) from 1972-2012. in the last 10 years, we stopped doing oil changes all together. Why throw away good oil? If you are using quality synthetic oil, there is no need to change. Synthetic oil should last forever. Simply change your oil filter and add oil as needed. Your engine will use oil, so when you add oil, you are, over time, always keeping the oil "fresh". I haven't changed oil in any of my cars and bikes in at least ten years. I have never had any motor damage, and I used to drive 7-8 thousand KM a month.

Wacki,

All true. And as long as I have a bike still under guarantee, I will follow the service instructions to the letter. I have never had a new bike before. Always a used, sometimes VERY used bike. But like I said, never had a problem with not changing oil. And anyone who passes up Einstellen der Ventilspiele is a fool. Easy to do, or at least on my Trudy, so I will do my Ponies, when the guarantee is out. Some things you NEVER pass up on.
