Blends[edit]
Biodiesel sample
Blends of biodiesel and conventional petroleum derived diesel are products most commonly distributed for use in the retail diesel fuel marketplace. Much of the world uses a system known as the "B" factor to state the amount of biodiesel in any fuel mix:[5]
100% biodiesel is referred to as B100
20% biodiesel, 80% petrodiesel is labeled B20[1]
5% biodiesel, 95% petrodiesel is labeled B5
2% biodiesel, 98% petrodiesel is labeled B2
Blends of 20% biodiesel and lower can be used in diesel equipment with no, or only minor modifications,[6] although certain manufacturers do not extend warranty coverage if equipment is damaged by these blends. The B6 to B20 blends are covered by the ASTM D7467 specification.[7] Biodiesel can also be used in its pure form (B100), but may require certain engine modifications to avoid maintenance and performance problems.[8] Blending B100 with petroleum diesel may be accomplished by:
Mixing in tanks at manufacturing point prior to delivery to tanker truck
Splash mixing in the tanker truck (adding specific percentages of biodiesel and petroleum diesel)
In-line mixing, two components arrive at tanker truck simultaneously.
Metered pump mixing, petroleum diesel and biodiesel meters are set to X total volume, transfer pump pulls from two points and mix is complete on leaving pump.
