... that biodiesel is the solution to low-lubricity problems, not the cause of them. Adding 1% of biodiesel increases lubricity by 60%. The biodiesel industry in the US sees the pending arrival of USLD (ultra-low sulfur diesel fuel) as a great marketing opportunity, as adding even a small amount of biodiesel solves the lubricity problem for older motors without the need for an expensive retrofit. This is one reason that in France all diesel fuel contains between 2 and 5% biodiesel.
