I am going on a 6000 Mile Road Trip in 2 days and developed an oil leak, probably stemming from the oil pan plug. But I didn't know what the problem might be, and of course this is the weekend now. So I Googled mechanics in my area, hoping someone might be open on the weekend, when I saw the listing for nail in the head. He explained to me what no one else had, that oil plug washers should be changed when the oil is changed, in later model cars. The last time I changed an oil plug washer, it was considered a specialty item and could only come from the dealer. I didn't know that auto shops now carry them. He explained that to me and was totally okay with me taking care of it myself. He would have had to drive up from Denver to do it himself. And reasonably so, he would have needed to charge me $160. I offered to pay for the knowledge he gave me, but he played that down. I will definitely let friends know about his business.
