There's a joke you see every now and then when someone says they have a low oil level.
"get a longer dip stick to reach the oil"

How Long Is Your Dip Stick?

I sometimes get asked the length of specific engine dip sticks. Either they have lost or
broken their one or they are sold a replacement and don't believe it's the correct one.

This is how we are measuring the dip sticks. With a tape measure!



The zero is butted right up against the collar of the dip stick.



The oil maximum and oil minimum are then measured off in millimeters (because fuck inches).
