Went to Hill Petroleum in Arvada to get Diesel. Paid $2.559 for #2. Bio-Diesel cost $3.499

per gallon. Where is the savings there? So what if you get 45MPG out of your diesel powered roller skate

, it still costs $0.077 per mile in fuel! A gas powered roller skate that gets 28 MPG will cost $0.0567 per mile in fuel costs. Where is the equity? GregH
