E10 Fuel Efficiency

The majority of us are using E10 fuel in our cars now. For the unlucky ones that cannot due to engine damage, it has been an expensive few months as the E5 Super Unleaded alternative is around 10-12p a litre more. This has impacted around 700,000 cars that. However, some are worried they might not be getting the same mpg due to E10 fuel efficiency.

What actually is it?

The component is ethanol. That is what has change in our fuel, from 5% to 10%. An article in the mirror stated that some motorists have noticed having to fill up slightly more often than before. One motorist said, “You get less mpg because the new fuel is less efficient”.

An message from the Gov.UK website stated, “You may see a reduction of around 1% but it is unlikely to be noticeable in every day driving.” The message then went on to say fuel efficiency would be more greatly impacted by under-inflated tyres, aggressive driving styles and carrying a roof rack on your car. However, there have been some real-world tests conducted by drivers and they have found it to be as much as 9% less efficient.

Why have we made the switch?

The reason we made the switch to E10 is due to it being more environmentally friendly. This is due to two reasons. The first is from on-the-road greenhouse gas emissions being reduced by around 6% but secondly, in the manufacturing process. Ethanol is mainly produced from processed corn, compare this to the process of drilling for oil and refinement and you can see why it is a less environmentally damaging process.

What are the alternatives?

That is not the end of the story though, synthetic fuels have been developed that are not made from traditional fossil fuels. These fuels have been compared, measuring Real Driving Emissions and within a lab setting.

One finding from the comparison was that larger particles emitted from vehicles using the synthetic fuels was reduced by around 85%. However, the weight of NOx emissions created from synthetic ‘e-fuels’ and E10 on the road have found to be around the same and in some cases marginally higher. These are the fumes that contribute to severe respiratory problems and form acid rain.

Two out of three of the synthetic fuels tested were found to create around double the quantity of ammonia. High levels of ammonia inhalation can cause their own set of respiratory problems. Julia Poliscanova, senior director for vehicles and e-mobility at T&E said, “As long as fuel is combusted in engines, toxic air will persist in our cities.”

Is there a solution?

Every year in the UK, 36,000 premature deaths are caused by air pollution, that means the only way to combat this is not non-emitting vehicles. The move to EV is a step in the right direction as they do not produce any on-the-road emissions and if the electricity to power them is from a sustainable source- then there are emissions slashed there too.

How can we help?

If you are thinking of swapping the petrol pump for the charging plug, then we have some options for you at Van MonkEV and VM Vehicle Solutions. We can discuss the options we have for you and make EV a viable option.

As always, thanks for reading and we hope to speak soon!
