Our best-ever diesel is designed to work well in all diesel engines and especially the latest ones with sophisticated fuel injection systems.

Cetane is the key measure of diesel fuel combustion quality. It relates to ignition delay - the time between fuel injection and combustion. Good quality combustion occurs with rapid ignition, and then smooth, complete fuel burn.

With a cetane number of 55 minimum, significantly higher than normal, BP Ultimate Diesel burns more smoothly and completely than ordinary fuel. So it releases energy more efficiently, which contributes to better engine performance

But if you are lucky enough to not notice the difference. Keep using the cheaper Diesel.
