The National Oilheat Research Alliance has recently released the results of a survey on the usage and potentials benefits and issues associated with the blending of traditional heating oil with renewable biodiesel for home heat use.

Currently, 5% biodiesel blends (B-5) are being used seamlessly across the oilheat market. Some heating oil fuel marketers are delivering B-20 to all of their customers and a few are delivering much higher blends. This blending into the fuel mix in this market leads to concerns about the impact on reliability and service.
