They are very dishonest - I would avoid Oil Star. There are plenty of other reputable merchants. Here is what happen: I stopped by one afternoon and asked if I could just get my windshield wipers changed (I had an oil change just 2000 miles ago). I checked back again and said again that I JUST wanted to get my wipers changed and they said ""Yes, got it"". 10 minutes later, I find out that they changed my oil and billed me $66 additional. When I disputed the charge, the man became extremely hostile and started yelling at me, and accused me of trying to get a free oil change!
Cons: Dishonest
