I used to know a lass that thought you filled up the oil through the dipstick tube 
She was parked outside my house once topping up with oil for about 15 minutes, I eventually went out to ask what the hell she was doing and saw the crudely knocked together funnel and pipe she was using to put the oil in the dipstick tube..... I started laughing and asked why she never thought to put oil in the big hole underneath the cap that has a big f**king oil can on it!!!!!
because putting oil in the "big hole" would be simple, logical, smart and normal, and as all men know, women aren't any of those things!

well, with the exception of simple that is.
