You can run 100% HPR or any ratio mixed with regular #2 diesel without harming the bluetec. In its literature MB calls this stuff HVO or renewable diesel.

Just refilled with HPR and managed 35.6mpg over 943 miles (tank plus two NATO jerrycans) of driving in Bay Area traffic. Thats about 2mpg less than my average but i think i spent a lot more time in traffic than usual so I dont know. This fuel has 5% less btus per gallon than #2 diesel but at the same time it burns more efficiently because of the higher cetane. I was also flooring it more often just for fun. So far I think its a wash for economy.

HPR was 40c cheaper than #2 and 45c cheaper than regular unleaded.
