Anybody heard of or know anything about Ecco+ diesel? A local Shell station has this on their pump. Min Cetane 42. All other diesel around here is 40 cetane. I asked the cashier what it means and he didn't know but said it was not bio diesel.
Fuels with lower Cetane number have longer ignition delays, providing more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher Cetane number fuels.
So there may be an advantage of higher Cetane rated diesel fuel when it comes to air pollution because of faster more complete combustion. Or at least in theory.

not really, octane in gas is resistance to knock
cetane, you want it to have better properties to ignite under compression.
Higher cetane is better until a certain point of diminishing returns.
Shell has SunDiesel which is biomass-to-liquid fuel, which is approved by the diesel manufacturers in Europe, as it does not gum up critical diesel injection components, like a traditional FAME biodisel
