These figures were used to create the charts Image:Oil consumption per day by region from 1980 to 2006 no labels.svg and Image:Oil consumption per day by region from 1980 to 2006.svg. Snapshots of those two charts are included here.
Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. If the engine is cold, or there is an excess amount of cooling around the cylinder, [ 1 ] the fuel oil will condense and have a higher chance to end up in the ...

The term Malaise era refers to a period in the U.S. automotive industry from roughly the early 1970s through the early to mid 1980s, characterized by malaise: poor products and a generalized industry unease [1] — an era of profound adjustment as the U.S. automotive industry adapted to meet wholly new demands for more fuel-efficient, safe and environmentally responsible products.

Waste oil is oil containing not only breakdown products but also impurities from use. Some examples of waste oil are used oils such as hydraulic oil, transmission oil, brake fluids, motor oil, crankcase oil, gear box oil and synthetic oil. [53] Many of the same problems associated with natural petroleum exist with waste oil.

The actual amount of mechanical work obtained from fuel (the inverse of the specific fuel consumption) depends on the engine. A figure of 17.6 MJ/kg is possible with a gasoline engine, and 19.1 MJ/kg for a diesel engine. See Brake-specific fuel consumption for more information. [clarification needed]
