Lucas arrived within the one hour window that was specified. He was friendly and seemed very knowledgeable. Although he performed a simple oil change, he was able to answer additional questions I had and tell me what things I needed to keep an eye on in the future. When he was done and starting to clean up, he noticed that part of the old oil filter was missing. He didn't hesitate to immediately put the van back up on the jack to inspect the oil filter housing, and found the missing piece from the badly worn out old oil filter! I appreciated his thoroughness and attention to detail.
