Its very entertaining to see what the difference in fuel quality will do to cosumption and pumps etc, as even the slightest hint of water will produce the slime and clog up everything!!

The only sollution I found after loads of problems, is getting the stuff straight from the refinery and having my own tank and pump.

Still here in Greece, every couple of months the rethink the ratio of ingridients, according to the bio-diesel's supply. When there is more biodiesel in the mix, my trucks tend to smoke more and consumption is worse.
