My Son told the Dealership (Davis-Moore Mazda)to do an Oil Change on his Car back in October when it was in there for something else and thought that it was done since he told them to do it. He thought one was done. On April 9th he put in at least 3 Quarts of Oil. On April 17th, his Car Engine Blew. The Car Burned all of the Oil within 1 week. I have contacted several Dealerships and they state that if the Oil was not Changed that it would cause the Engine to Blow. They refuse to pay for it and keep lying to us about everything. I get a different story everytime I talk to them. I also just found out after complaining to them that they only topped off the Oil in October and are trying to blame my Son for it. They refuse to take responsibility for something that they caused.
