I completely agree with your post, save one small detail. I have
to address it.
"Dirty diesel smoke" is inaccurate today. Diesel fuel is one of the cleanest hydrocarbon fuels on the market. Ultra-Low Sulfur Diesel (U'___') is
required by Federal law to be used exclusively in truck engines manufactured in 2007 or later. The new engines also use a diesel particulate filter
that requires constant maintenance to get the exhaust clean. We pay a hefty price for this cleanliness and environmental friendliness through lower
mileage and more maintenance time, with no compensation from lower fuel prices or higher mileage for the newer diesel.
The pictures I am sure everyone has seen, of that big ol' truck spewing a column (sometimes two) of dark black smoke simply do not exist anymore.
Years ago, truckers recycled their used motor oil by pouring it into the tanks and burning it as fuel. That's where the black smoke came from. Diesel
fuel is a type of oil anyway, so the motor oil burnt just like fuel. They didn't get much use out of it, but what little they got was basically free.
That is now illegal and I have not seen it practiced in over 7 years of driving.
The new U'___' contains less than 15 ppm (parts per million
) of sulfur. That's about as clean as you are gonna get it, and definitely cleaner
than gasoline. So can we deny some ignorance about trucks belching columns of black dirty smoke while we're here?
