Maybe it's true that waxing gives you better service intervals. I don't know, as I will never wax my chain. The important thing for me is how much time the service takes. Dripping some oil on and wiping a rag is sufficiently quick for me. I live in New York, and our climate became sub-tropical a couple of years ago. So now rain is frequent enough that I don't need a calendar-based reminder. I just oil after the chain gets wet. I use heavy oil which, in theory, lasts longer than light oil.
