The National Petrochemical & Refiners Association recently published its
2002 industry info.  2.46 billion gallons of lubricants sold in the Untied
States in '02.  Only TWO percent were in the '2-Stroke, Aircraft, and Other
Engine Oil' category.  That 49.2 million gallon category breaks into
2-Stroke (16 million gallons), and Aircraft oil (6 million gallons) (the
'Other Engine Oil' is 55% of the category...).  Aircraft oil includes both
piston engines and jets.  While these weren't broken into gallons, you can
guess that jet engine oil is the lion's share of the category.

Gasoline engine oil is 31% of whole; diesel engine oil is another 14%.
Transmission and hydraulic oil are 11%.

You can probably guess where the R&D money goes (or doesn't go...)...
