text: customers be ware They did an oil change on my car a Hummer drained the oil and never put new oil in and while my daughter and I are driving my car starts stolling at every corner we put the lid up and there is oil in it bone dry I take our car to there location on Rancho and they basically told me that my enginge blew up and it was not their fault even tried blaming it on the people who did my oil change before them since my car would not work and I took it there thinking they would obviously own up that it was their fault my enginge blew I mean its common sense that when you have no oil in the car your engine blows and I had just had an oil change by them day prior I thought they would obviously have known it was their fault since I had just had the oil change and there was oil in it but no they did not so I had no choice but to pay them for a NEW ENGINE AND LOW AND BEHOLD YEARS LATER THE ENGINE THEY PUT IN IS NOW NOT WORKING I WENT TO ANOTHER TRUSTED MECHANIC AND THEY TOLD ME THIS WAS A USED ENGINE NATIONAL AUTO SOLD ME WHEN I WAS TOLD IT WAS NEW At the end of the day the joke is on me as since they did not put oil in my humer after a oil change why on earth did I think they would put a honest engine it in I only did it because the car would not start and thought because of what they did they would do a beyond a a good job FYI THEY HAVE A F RATING ON THE BBB
