Just checked Your Mechanic. $40 for an oil change? no thanks. Not worth the convenience. It will fail at these prices.
(Now, I know you think, everyone can just change their own oil! But for those of us who are apartment dwellers without space for all of the tools? We're a bit stuck. That's not counting the places where we aren't allowed to change our own oil -- I'm not sure how Your Mechanic will work around this.
I'm more worried they won't be able to get the density required to make this worthwhile in the first place.
I'm also not even sure what an average oil change costs? Without that knowledge, because I haven't done it often enough to know, $40 actually seems perfectly reasonable.
