I got my oil changed and later opened the hood and saw splashes of white powder near the battery, and dried up orange gunk around the coolant reservoir. I showed it to Bill and he said he would do a steam clean at no charge. So, not only did they clean the engine, they also washed the car and blacked the tires. Looked like a wax job! No cost to me. They give great service and make it right all the time.
