I always believed in going to the dealership to get my oil changed. However, last weekend I needed to get my oil changed without worrying about getting an appointment. I ran up to the Walmart on Carroll Island Rd, I registered my car and then went to pick up the few items I needed while the oil was being changed. They had it ready within 1/2 hour. The employees were very friendly and efficient. It was also very good not to have to waste the 1/2 by being able to get my shopping done at the same time. This store is very convenient.
