2012 MDX w/ 205,000 miles. Changed it once at 105k, and dealer wants me back tomorrow for a second one. The car looks brand new, all highway miles, but with a book value of $8k, I hate pouring money in knowing the value will just keep going down with mileage. Curious when people typically do the second change, how critical the 105k mile intervals are, etc? Thanks in advance for any insight!
