It is used in the UK and Commonwealth countries for liquid measurement, though everyday use has declined since metrication. An imperial quart is larger than both the US liquid quart (946 mL) and just slightly larger than one liter. Historically, motor oil was sold in imperial quart cans in the UK; today, liter bottles have replaced them.
Pre-metrication UK motor oil was sold in imperial quart cans. An imperial quart is just over two UK pints.
