I came here for the advertised $12.99 oil change. I didn't stay to wait, but went to the Chinese restaurant next door for lunch. I cannot speak as to how long it took.
Upon returning, the desk worker told me I had to speak with the mechanic. The mechanic then informed me my coolant was low and my air filter needed to be replaced. He wasn't particularly confident in the upselling, and kept looking to the desk clerk for support. I'm not quite sure why I had to speak with the mechanic if the clerk knew all of the information. While the mechanic was showing me the air filter, he poked a hole in it with his finger. I was reluctant to have it replaced as it was an easy repair to do myself, but after that I refused. I did it in the Walmart parking lot for $5 less.
As for the oil change, it was lacking. The sticker most facilities place in the upper left corner of your wind shield was missing, and the oil change light on my dash was not turned off. I will have to remember to change the oil at 163,600 miles. This seems like a good enough spot to leave myself a note. They probably changed the oil though, I hope.
