TL;DR I think this is a reasonable assumption. Anecdata: Just over 250,000 on my 2007 Honda CRV and with $1k in unscheduled mechanical maintenance and around another $1k in non-mechanical maintenance. Assuming a 10,000 mile oil change cycle (I only change the oil when the car recommends it, and it seems to avg about 10k miles) that's 25 oil changes so far, for a total of ~$1800 (assuming dealer oil change + full synthetic, which has been all but two of my oil changes so far; does not include tax). Warning, opinions ahead: In my experience, most people do not follow the recommended preventative maintenance plans for their vehicles, and rely solely on oil, tires, and gas changes, and all three only when necessary. Here be dragons: At an over-all average MPG (according to the car's own computer) of 25, I've spent more on fuel than the cost of the vehicle, including loan interest, in the 250,000 miles. Getting waaaaay out there: 32k for car + interest, 35k in fuel, 10k in other scheduled work (I believe in preventative maintenance), upgrades, cleaning, etc for a total cost of ownership of about ~80k means I've paid ~$3/mile driven.
