You peaked my curiosity. I purchased a 2014 Pilot new in January 2014. It now has 108,000 miles. I've done all maintenance myself. The vehicle has never been serviced by a professional mechanic. Not once! I've followed the maintenance minder for services. Codes come up and the owners manual tells you what they are for. I use Mobil One Extended Mileage
Full synthetic Oil with Fram Ultra Synthetic filters from Walmart and OEM parts from the local dealer when needed. Here's the list
3/30/14 - 6,065. Oil & filter (O&F)
6/14/14 - 14,227 O&F, VTM4, Tire Rotation
8/28/14 - 22,353 O&F
11/22/14 - 30,268 O&F, VTM4, Tire Rotation, ATF, Transfer Fluid, Air Filter
4/5/15 - 39,105 O&F
7/3/15 - 48,596 O&F, Tire Rotation
9/20/15 - 57,296 O&F
1/10/16 - 66,908 O&F, VTM4, ATF, Transfer Fluid, Air Filter, New Michelins from Costco
4/9/16 - 75,313 O&F, Tire Rotation
6/26/16 - 83,747 O&F
9/16/16 - 92,583 O&F, Tire Rotation
1/15/17 - 102,275 O&F
3/15/17 - 106,125 O&F, VTM4, ATF, Transfer Fluid, Air Filter, Spark plugs, timing belt, water pump, coolant, pulleys, belts, front pads and rotors. (All the timing belt service components appeared to be in excellent condition...felt wasteful to throw them away, but I did)
THAT'S IT! The vehicle hasn't given me one bit of trouble. I guess I did forget to put a couple wiper blades in the list. Looks like I am going 8-9k miles between changes...nearly 10k once. I'm going to keep this vehicle for a couple more years so it will be interesting to see if there are any noticeable effects from the extended oil changes.
It scares me to think how much would have been spent had I brought the vehicle in for regular service by the dealer. Edit - just did a tally and my total maintenance material costs are about $2,000 including tires and the complete timing belt service I just completed! Of course I'm not including my labor cost, but my maintenance on this vehicle is about two cents per mile so far. Gas is approximately 13 cents per mile.
BTW, I tow a 4,000 lb boat & trailer quite regularly. Tranny and VTM4 fluid always looks clean. Transfer Oil looks new.
