Hello All,
Although I've run B99 and B20 in a number of diesel engines, some built before 1992, some after, I've not run either in anything heavy except the other day I ran a 1978 D3 that a water district was trying to sell and they claimed they'd run B20 for quite sometime without issue, except maybe when someone ran the tank low and then it sat for months of disuse, possibly causing some gel and sluggish start.
I've heard rumors that I've never personally experienced, of pump seal degradation, general rubber line decay and certainly warranty jeopardy, but aside from seeing B99 melt an old Benz tank filler grommet, I've not seen these issues. Does anyone have any experience with Biodiesel in earthmovers, even just power issues with it, apparently a less dense fuel that petro-diesel? Of course the euphoric on biodiesel claim that it has great system cleansing properties, which sounds good, I guess, until something important melts....
TIA for your thoughts...
