[SEL] Non-detergent Oil--The Rest Of The Story

[Larry Evans]

About then (10 or so years ago) I got into a discussion with John Culp (who 
seems to be well versed regarding petrochemistry) about this issue.  His 
feeling was, as I recall, that the early oil was far different from today's 
non-detergent oil in that it contained natural products that acted in some 
respect as detergents.  With today's refining technology non-detergent oil 
is not the same product as "pre-detergent" oil.
