weight of diesel per litre

Diesel fuel weighs approximately 0.832 kilograms per litre, but don't get too precise—temperature and formulation can tweak that number slightly. It's denser than petrol, which clocks in around 0.74 kg/L, so your diesel tank holds a bit more mass for the same volume. This density is why diesel engines often deliver better fuel economy and torque. Remember, always check the latest specs from your supplier or official sources, because fuel formulations can vary.
