Unpopular opinion. I'm so frustrated I hate car shows/cruises.
Years ago I was at at show and had the hood open on the 66 Barracuda. There were two elderly gentlemen looking at it(I knew the one gentleman), his friend leaned over and pulled the dipstick and checked the oil level, wiped it clean with his fingers ! Wiped them clean on his pants and said ” Yup it’s clean”
