Yeah, an oil thread.
Honestly if you have oil in the motor you're good. Most of us get a new bike every few years so it doesn't matter.
Here's some food for thought, the Army doesn't change oil. They send it out for analysis, change/clean the filter and add oil as required.
Also the airfilter has more to do with keeping oil clean than the oil filter.
Lastly my 02 Carrera has an oil change interval of 18, 000 miles.
My Ape is changed once a year. Good enough.
