| Comment | I am opposed to additional inspection requirements or the
imposition of retrofit devices on my stock(unmodified in any
way)diesel engine. A new verification program equates to
additional and unnecessary costs to me to prove I am compliant
with the law. CARB's mandate would be better-served by stricter
controls (read: prohibitions)on the sale of aftermarket
performance equipment for diesels such as tuners or auxillary
programmers that change stock powertrain operating parameters.
Imposition of new, stricter emissions requirements should not be
retroactive. Currently registered vehicles are not the problem;
attrition alone negates any long-term adverse environmental effect
from privately owned pick-up trucks (including one-ton models)and
diesel powered cars.
"reburning" of used crankcase oil in diesels should be prohibited
as well. Some commercial trucking entities supplement their fuel
with used engine oil. Some engine manufacturers publish guidelines
relating to recommended amounts of oil that can be intoduced to the
fuel supply.
