I took my car in for a simple oil change and was told I needed an engine flush and an engine additive. I agreed after hearing their pitch for 5 minutes. After $137 I was on my two mile journey home. The next day as I was on my way to work my car started sputtering, shaking, and then the check engine light came on. I had to have to towed back to the location. The guys said they could have not tightened a hose or they could have put something on incorrectly. After an hour and a half they still could not find what was wrong. I have my Mazda towed (again...2nd time in two days) to the Mazda dealership. Apparently something was dropped into (or on) some sensor and cause something to happen. I am still waiting for my car to be fixed and when I do it is going to cost me a $260 to fix. I promise you I will NEVER go to this place again. I will never go to one of those places again...Buyer Beware!
