Biodiesel B5 is a renewable fuel made from 5% biodiesel (made from used cooking oil) blended with 95% petroleum diesel. It provides environmental benefits like reduced emissions and is supported for use in diesel engines by major manufacturers. Lootah Biofuels produces Biodiesel B5 by collecting used cooking oil, converting it to biodiesel, and blending it with petroleum diesel. They distribute B5 through fuel stations in Dubai and offer it at a lower price than conventional diesel to customers. Using B5 provides savings for customers while helping reduce waste and carbon emissions compared to petroleum diesel.
