Dipstick Identification and Specifications

Regarding the handle type "old" refers to the style where the handle is made of flat steel just like the dipstick. The "new" style is the type that has a round tubular handle. The cup is also different on each therefore the measurement is taken from the top of the cup where it would seat down onto the dipstick tube in the engine.
