Sounds like you're on top of it amigo, and probably a good thing too, as the weather is absolutely perfect here for riding - was in the mid 80's all weekend, and I was loving it! I'm thinking it should be getting pretty nice there too, eh?
18,000 mi on an oil change??? Really? Holy smokes! I never would have imagined. I am assuming BlackStone Labs is some place you can send oil to where they can analyze it to see how much viscosity is left...? If that really is true, it is truly mind-blowing, and something I bet all the motor oil producers do NOT want any us to find out.
I will be looking forward to hearing what the results from yours are. Have fun getting your ride ready OD, and even more fun gettin' your scoot on the road.
Have fun and ride safe my friend : )
