Its not just fuel.
Cetane number is the key measure of diesel fuel combustion quality. The number relates to the ignition delay - the period that occurs between the start of fuel injection and the start of combustion. Good quality combustion occurs with rapid ignition followed by smooth and complete fuel burn. The higher the cetane number, the shorter the ignition delay and the better the quality of combustion.
As it happens BP has one of the highest cetane readings available in the UK.

What is Shell V-Power Diesel like? I have started using it and again have seen a slight improvement in MPG.
