TUCSON -- The city is moving toward using B20, a 20% biodiesel blend, in trash trucks and other diesel fleet vehicles.
This is a good idea. No conversion required, just start using B20.
Biodiesel reduces smoke, stink, and global warming pollution.
Using biodiesel also helps Tucson do more to curb America's expensive war-causing foreign oil addiction.
When replacing vehicles, the city should keep and buy more diesels, and fuel them with B100 pure biodiesel for even more benefits.
My family uses biodiesel to power our VW TDI, and it works great.
