AutoNation Former B&B I paid for oil change and they drained the engine without replacing the old oil. Mesa, Now Gilbert Arizona!!. I prepaid to those crooks for each of my cars, for four oil changes and two tyre rotations. Three weeks after the second oil change the cars’ controllers (computers) showed low oil levels in both cars. Manual checking revealed that there was virtually no oil in the engines. The cars could have caught fire. It is clear what happened. They drained the old oil but they did not replace with new. This used to be a vey good business. When it was still owned by the local Brown family and was called Brown&Brown. When the old guy sold the business to out-of-state criminals, it became what it is today.
