Oil changes are pretty straightforward. Drain the oil. Remove and replace the oil filter. Put the drain plug back in. Remove the oil fill cap and add the appropriate five quarts of oil. If you are having your neighborhood service guy doing the oil change this is the point where he backs the truck out of the garage.
Then you see the service guy put the truck back in the garage and get the assistant manager out in the shop. They open the hood and walk around the shop looking for something while you peer through the window of the "No Customers Beyond This Point" door.
The service guy disappears and the assistant manager asks you to come look at the engine which is now covered with oil. His explanation is that the seal on the filler cap blew and he's never seen anything like that before.
It's clear that when the service guy started to back the truck out the engine attempted pressurize and the oil light came on after blowing oil all over the engine. The important last step of the oil change is to replace the filler cap.
So I drove home in a 'loner car.' Tomorrow they will clean up the engine. I'm placing a bets between "Sorry, the mechanic left the oil cap off" or "The seal on the filler cap blew and we had to replace it at $nn.nn." My guess is that the manager will force the assistant manager to speak very creatively with much emphasis on "We've never seen this before." Perhaps the oil filler cap should be tethered to the appropriate location, like the gas tank cap.
Of course I dropped the truck off at 8:15 AM for a 10:00 AM appointment. The "I've never seen this before" explanation was at 6 PM....and now we move into Day #2. Good grief.
