Jiffy Lube --Greenwood

They change your oil without an appointment. They do a decent job, not that it's a hard thing to do. The price is reasonable. Not the cheapest, but the service is pretty good.
The only thing I don't like is that they always try and sell you something extra, when all I want or need is an oil change.

PROS: Quick, inexpensive and convenient
CONS:

There is another Jiffy Lube up the street, but this one--#2082--has better employees. Just off Holman Road, which later morphs into Northgate Way and 105th, Jiffy Lube 2082 has polite servicepeople that carefully explain everything they could do to make your car a better machine. Also authorized to do minor repairs, this Jiffy Lube gets you in and out amazingly quickly, especially on Saturday afternoons, which means you don't have to pretend to be interested in what's on TV in the waiting room for too long!
