Fuel consumption at 15 tonnes

Hey… hope someone can help me… I’m looking for fuel consumption data from certain trucks. The manufacturers are very covered. I already know that the consumption is very dependent on the vehicle (un/loaded, driving mode, etc.), but there must be average or minimal/maximum consumption data. Work in a construction company and we are currently catching up with various offers. The vehicle itself is a truck with a loading crane behind the cab . MB Atego 177PS MAN TGM 240PS DAF LF Series 220PS Iveco Eurocargo 182PS Renault Midlum 220PS Nissan Atleon 251PS Volvo FLL 256PS Would be cool if someone here knew some data. MfG Johnny
