A few years back, our customers sought advice on poor fuel economy during winter months, particularly with diesel-powered vehicles. This phenomenon is easily explainable. The reason is that many fuel companies around the colder parts of the world, the UK being one of them, switch fuels during winter. This usually occurs in the UK around November.
This is necessary because it provides greater protection against gelling and waxing, typically providing additional protection of up to minus 15 degrees centigrade, as opposed to the standard minus 5 degrees during colder spells. The downside is that this fuel usually has a lower BTU (energy) value than the summer equivalent. This results in less energy being produced during the combustion process, and thus your engine requires more right foot to attain the same level of accelerative or cruising effort.
There isn’t an immediate solution other than to use a high-quality combustion modifier or fuel catalyst additive to help maximize the energy capability of the fuel. No additive can increase the BTU of fuel, but you can ensure you get the most out of it and ensure it’s not wasted in the form of excess emissions or particulates. Also, diesel engines are more susceptible to carbon build-up during winter months as the engine takes longer to get up to temperature, which can ultimately lower the MPG.
A diesel additive with combustion improvers can provide a much cleaner burn (even during engine warm-up conditions) with the added benefits of cleaning and lubricating the fuel system, preserving the fuel, and protecting against water and other contaminants.
