Lots of people up the interval to 5k, but if their oil is tested and Blackstone says it's still good to go longer, you're doing absolutely nothing but throwing away money.
Is it bad form to quote oneself?
I've been thinking about this and wanted to clarify. If your goals are optimal maintenance or to spend money only on what really makes a difference, it's unnecessary. If the oil and filter are doing their jobs, changing them early doesn't get the job done better.
HOWEVER! If the goal is to spend an enjoyable hour with the bike turning wrenches and feeling good about how well you take care of her, then by all means change the oil every month if you want!
I'm not going that route for engine oil changes, mostly because the tests take out all the uncertainty, and can tell me if there's work that needs done to better protect the motor.
Where I am personally going off the deep end is with bevel box oil. I'm not going to have it tested, because the only thing I could do in response to the test is change the oil more frequently. I don't need a test to tell me that. It uses such little oil that for less than the cost of one test, I can buy a bottle of the best stuff made once/year, and change the gear oil every two months through the riding season. Total overkill, but other than lubing the splines, it's the only thing I can do to take care of a very expensive part. It takes little time and money and makes me feel good so… why not! Whatever spins your beanie.
Sometimes, as in my earlier post, I state things too harshly and steamroll the bigger picture. Gotta quit doing that…
