Average AdBlue / Diesel Emission Fluid (DEF) to diesel consumption is estimated by various vehicle manufacturers at approximately 5.0 %, i.e. every 100 litres of diesel consumed, 5 litres of AdBlue/DEF will be consumed.
From our vast experience with Singapore fleet owners and vehicle dealers we roughly estimate the AdBlue / DEF consumption of various Class 5 Commercial Selective Catalytic Reduction (SCR) Vehicles (Euro 4 / 5). Actual AdBlue/DEF to diesel consumption is well below the 4.0 % region.
How much AdBlue do you need? Below are general estimation of the AdBlue/DEF monthly consumption, in real cases actual consumption may defer.
20 – 30 litres per month for school buses
40 litres or more for shuttle buses
Long Distance Buses
40 litres or more for long distance travel buses
Tipper Trucks and Prime Movers
20 – 50 litres or more depending on utilization rate
