CarSpa is a big lube shop/car wash in Midtown, but unlike similar places, CarSpa doesn't have the mall-on-Christmas-Eve parking-lot atmosphere that might make you change your mind before pulling in for a quick oil change. The shop doesn't do appointments, so it's a first-come deal. But the wait shouldn't be longer than an hour. A straight oil change costs $25, and that comes with all the standard fluid, tire and belt checks. The price might be a tad more expensive than at other places, but it includes a free car wash when the oil change is complete. If you roll on dubs, you can get a professional polish for an extra $20.
