quote: How many more disastrous weather events do you need to wake up and do everything possible to improvement everyone's environment?
quote: Corporations running politics for profit will hurt everyone's children.
quote: Further hurting the cause of diesels is that 15 U.S. states place additional taxes on diesel, and federal taxes for diesels are 6 cents higher than those of gasoline-powered autos.
quote: Until the ULSD standards were put in place on diesel, it used to be cheaper per gallon than low grade gasoline.
quote: Diesel and gasoline are commodities. When demand is high and supply low, prices rise. When demand is low and supply is high, prices fall.
quote: The fuel companies simply know that most gasoline vehicle owners can just scale back their driving as prices go up, where most diesels are commercial vehicles which need to be rolling to make money. Diesel drivers as a whole thus are less capable of "voting with their wallet".
quote: and that particulate matter isn't really a big deal.
quote: economical low engine speeds mean exhaust gases don't get hot enough to burn off the particulate matter--leading to clogged filters and expensive replacements.
quote: So any diesel smell you noticed, is from the 1980's and 1990's diesels that are still going strong.
quote: Modern clean diesels are *cleaner* than gasoline engines
