I've been running Propel's Hpv diesel and no issues. Same mpg and actually feels just a bit snappier on initial throttle. I do think the injectors are louder though which is odd because lubrication wise it's supposed to be better.
I know the bio stuff got a bad rap because of the fuel filter issues but like the propel stuff it has a cleaning agent that was basically breaking up all the garbage you had in your tanks especially on the oolder trucks and taking out filters like no tomorrow.
