I have a friend that often checks other peoples oil. Guests to his house or his kids friends cars etc. Anyone parked at his house. The interesting part is that the other people don't konw he does this. He adds oil, water to the battery or anything else he notices that the car needs to have added. Even air in the tires. I guess he feels he is performing a service and helping the people. Kids cars, ladies cars, and "company cars" need a lot he says. He once found a company car that need three quarts of oil.
Any thoughts?
