If folks back in the day (I was 7-years old then…) used this as a good idea on how to care for their car, then that explains why so many have been scalded from boiling hot radiator coolant by popping the cap on a freshly run engine… (25-seconds in the video…)
Later on in the video when the attendant checked the oil brought back memories of my first car ('54 Dodge…). I bought it off my neighbor who was selling it because it was hard to start in the New York winters… As it turned out, the local garage that did the oil changes used straight 30W oil with the 10-30W so it was had to start and it ensured them of lots of calls to go jump batteries…
The same garage, when they did oil changes, punctured the oil can in the bottom, and then put that empty can on a rack to drain every last drop out of it… Then when they checked to oil of a car at the pump, the first check was to see if the oil level was full, if it was, they wiped the stick and “re-checked” the level, but this time, they wrapped a finger around the stick to keep the stick from being fully inserted and the stick would come back showing a quart low. They were “very professional” and they would show the customer the dip stick. If the customer told them to add a quart, they would grab one of the cans off the top of the oil rack (46-seconds in the video…) and those cans on top were the empty cans from the shop, with the hole punched in the bottom… They would puncture the can on the top and carefully wrap an oil cloth over the can “to prevent spills…” (actually to cover the hole in the bottom…) it looked all so professional… They then “re-checked” the oil level and miraculously your oil level would now be fine…
If a customer should pick up one the empty cans in the rack, “old John” would curse up a storm at his jockeys for “putting” an empty can back in the rack.
But still a fun video to watch…
