I just bought a 2011 e350 Bluetec, and noticed HPR for sale. Per Propel's website, it meets ASTM D975 requirements. Per MB, "If the diesel fuel meets the required ASTM D975 standard, it is acceptable for use with your BlueTec diesel."

Does anyone have any concerns with using this? I am not too concerned given certification, and Propel states online that they add a lubricator to it (though I am not sure of the final lubricity rating). Car still has low mileage, so just don't want to do anything to harm it.

Also, price for HPR was 2.95, which was 10 cents less than standard diesel that day.
