REG Ultra Clean™ Diesel — The Perfect Blend

The latest innovation in renewable fuel is a blend of biodiesel and renewable diesel that creates one of the lowest carbon intensity liquid fuels available. Patent-pending REG Ultra Clean™ Diesel combines the best properties of both fuels including biodiesel's added lubricity and renewable diesel's high Cetane and low Cloud Point. Then there are the significant emissions benefits from blending renewable diesel with biodiesel. It's no wonder that REG Ultra Clean Diesel is an approved fuel by the California Air Resources Board (CARB), one of the most progressive clean air agencies in the world.

Features and Benefits

FeatureBenefit
Reduced emissionsThe best of both fuels’ emission profiles combine to significantly reduce total hydrocarbons (more than 20 percent), particulate matter (more than 40 percent), carbon monoxide (more than 25%) and NOx (by 10%) compared to petroleum diesel.* 
High performanceHigher Cetane for better performance, added lubricity for reduced engine wear, lower aromatics for improved public health and excellent Cloud Point for good cold-weather usage. 
Ease of useCan be transported, stored and handled without any changes to a petroleum diesel delivery and storage infrastructure.
Strong supplyWith renewable diesel demand outpacing supply, blending in biodiesel can help stretch renewable diesel allocations while still offering an extensively renewable product.  
CARB ApprovedApproved for year-round use by the California Air Resources Board, which oversees the state's Low Carbon Fuel Standard (LCFS).
