In most petroleum-producing countries, however, and particularly where the product is abundant, the crude oil is fractionally distilled, so as to separate it into petroleum spirit of various grades, burning oils, gas oils, lubricating oils, and (if the crude oil yields that product) paraffin.
The use of petroleum as liquid fuel is dealt with under Fuel, as is the employment of its products in motors, which has greatly increased the demand for petroleum spirit.
The more recent legislation with regard to " petroleum spirit " relates mainly to the quantity which may be stored for use on " light locomotives."
