Being a complete mechanical goober I did explain to a widow lady's granddaughter that Motorcraft fl1a filter and 10w30 oil was what was needed for the 1997 Fordf150 in the garage. She whipped out her smartphone put on a pair of gloves and changed oil just as fast as you goobers could've. 23 years old and asks "Why do they charge $54.72 for that.?" Hope springs eternal!
