Huh? Its sold by the quart, capacity charts are in quarts...but you could use milliliters if it floats your boat. The unit of measure has nothing to do with the subject at hand.
You are being facetious right?

Grab some old car manuals for Toyota, Honda, Ford, VW...though the stuff is sold in quarts, note the unit used often to note capacity - and the unit used often to identify what the tickers relate to on the transmission dipstick as opposed to the engine oil dipstick.
