100K is merely warm up mileage for a Honda or Acura as long as maintenance schedules are even somewhat adhered to. Here where I live in Nebraska , the road salt eats the body away long before the engines wear out. Probably easily get 300K out of it.
i just recieved my Sept 2017 issue of Consumer report and on page 55 CR lists 20 vehicles that are in their 200,000 mile club. The top 9 are all Toyotas and Hondas. Camry #1 then Accord #2. Another 100K or so on your Acura is not at all unreasonable.
to expect.
-------------------
2002 Honda CRV: 155K
2009 Hyundai Sonata : 189K
2010 Hyundai Tucson: 55K
OCI 4K to 5K with the cheapest regular 5w20 I can find, usually NAPA or Travelers from TSC.
