Also, it depends on where you live. Around here with all the dust and dirt in the air, better count on every 3,000. Because it isn't the oil break down that's the problem, it's the dirt contamination and NO; filters will not filter out all of it
How does dirt get in your oil?

every 3k-ish for me. Could probly stretch it longer, but $50 is worth the peace of mind to me
Through the breathing system. Even though it's what's called a closed system (which works OK if the bike is parked or stored) the oil contacts air in the crankcase. Filters are good, but if you live in a VERY dusty area (and I do out here) small particles will find their way through the filter system. That's one reason I've never understood someone changing oil, but not the oil filter. Once you fill with new oil, then crank the bike up, the oil just gets contaminated with the old oil in the OLD FILTER.
Every 3months or 3,000 miles.
I have done the "cheating oil change" a couple time over the years, but I will change the oil filter and top off with oil.
I don't understand adding clean oil to a dirty filter.
I always thought that was dumber than dirt too...4 quarts of clean fresh oil
plus one quart of old dirty oil from the old dirty filter equals five quarts of old
dirty oil...go figure. A filter is 5-8 bucks...???
Alisyn full synthetic @ every 1500 miles~!~
