Questions we are frequently asked
-
Red diesel (also known as gas oil) is a rebated fuel designed for off-road use. It’s chemically similar to standard diesel but dyed red to distinguish it and
indicate a lower rate of duty.
-
Red diesel should be stored in a suitable, bunded tank that meets current regulations. Good storage helps prevent contamination, reduces the risk of theft, and ensures you stay compliant.
