Biodiesel is supposed to be an extremely strong solvent. That's why when swtiching to biodiesel, it is generally recommended to change your fuel filter after a few tanks because it can plug up quickly. It's also the best lubricant you can add to diesel fuel, better than any other diesel fuel additives on the market. I run a 200:1 vegetable oil mix in my Metro. Not as clean s biodiesel because it still has the glycerin in it, but still better than nothing.
