Looks like you're getting the same general answers.
Here's a little insight in oil change interval. For one never exceed the manufactures recommended mileage interval. As stated before it's a bad idea when it comes to warranties. Two, did you perform an oil analysis to know how much and of what kind of contamination your oil is receiving? Three was the engine broke-in properly. Poor brake in leads to poor ring seating and oil blow by and excessive oil consumption. And Four, What on gods green earth were you thinking?
All engines are not equal they all wear a bit different and they all use a more or less oil then the other engines. it's just something they do. and even with the engine built to near perfect specs it will still burn a bit of oil over time.
I trust no oil past 5K and only 2K in my bike.
