Snohomish Co-op currently stocks B99 (99% biodiesel / 1% diesel) or B75 (75% Biodiesel / 25% Diesel) during the winter.
The use of biodiesel to extend diesel fuel and improve lubricity is growing rapidly. Biodiesel is produced from oils such as palm and soybean or from any fat. Biodiesel is processed (transesterification) and must meet strict industry specifications (ASTM D6751) and must be registered with the EPA before sale and distribution.
