We understand that you want help to reduce the impact of driving your car. And globally, we have exciting plans to increase the amount of lower emission fuels we offer(1). So now we’re launching Esso Supreme 25% Renewable Diesel, with 15% lower life cycle GHG emissions than our regular diesel(2).
Currently available at 20 Esso stations in South East England, and suitable for all diesel engines without adjustments, our latest diesel include 25% premium renewable content, and our proprietary Esso Synergy additive.
Not what you might have expected from Esso, but a convenient step in the right direction.
Esso Supreme 25% Renewable Diesel: Benefits
15% Lower Emissions
The fuel has 15% lower life cycle greenhouse gas emissions (GHG) than our regular diesel(2). If you use 50 litres of Esso Supreme 25% Renewable Diesel, the lifecycle GHG emissions associated with fuelling your vehicle will on average be 25 kg less than if you had used 50 litres of Esso Synergy diesel(3).
Two round trips from London to Edinburgh of emissions prevented
15% lower lifecycle GHG emissions means that for the average UK diesel car driver, using Esso Supreme 25% Renewable Diesel instead of regular diesel can prevent approximately 1,410 miles worth of lifecycle emissions associated with fuelling that vehicle per year(2). That is equivalent to over two round trips from London to Edinburgh(5).
We use the methodology outlined in the amended Renewable Transport Fuel Obligations Order 2007 (SI 2007/3072) as amended (“RTFO”), which includes contributions from N2O and CH4, expressed in CO2 equivalents (CO2e). The life cycle GHG saving from biofuels and bio liquids (e.g. HVO) is calculated by comparing the carbon intensity of the HVO fuel with a fossil fuel comparator, using RTFO default values for the renewable and fossil fuel comparators. In this case, the expected life cycle GHG emission saving of 15.2% for Esso Supreme 25% Renewable Diesel containing 25% HVO was calculated against the equivalent figure for regular diesel containing up to 7% fatty acid methyl ester (FAME).
GHG saving of biofuels & bio liquids = (E(F) – E(B) )/E(F)
E(F) = total emissions from the fossil fuel comparator
E(B) = total emissions from the biofuel or bio liquid
E(B) = E(HVO)
In the case of biofuels, life cycle GHG emissions will also include the emissions associated with cultivating, and harvesting the feedstocks used to make them. GHG emissions include carbon dioxide (CO2), methane (CH4), and nitrous oxide (NOx).
Renewable fuels have lower life cycle GHG emissions than their conventional counterparts because the carbon in those fuels comes from a renewable energy source (for example biomass, oil extracted from plants, or used cooking oil). In those cases, the carbon from those sources has been drawn from the atmosphere to feed the plant’s growth, and when the fuel is burned, that carbon is returned to the atmosphere without a net increase in atmospheric carbon. The important thing to remember is that it’s across the overall life cycle that the environmental impacts of biofuels are compared to conventional fuels, not at the vehicle exhaust emissions at the end of the chain.
Esso Supreme 25% Renewable Diesel meets the BS EN590 specifications and works in all diesel engines marked as compatible with B7 fuel. It can be used interchangeably with other diesel fuels, and does not require any engine modification. It will not impact the warranty of a vehicle engine marked as compatible with B7 fuel.
Pure HVO contains approximately 4-5% less energy per litre than conventional diesel, though this impact is diluted for blends of HVO. Esso Supreme 25% Renewable Diesel contains a minimum of 25% HVO, blended with conventional diesel and our proprietary Esso Synergy additive. It meets all BS EN590 fuel specifications. We therefore expect minimal impact to fuel economy.
B7 labelling means that Esso Supreme 25% Renewable Diesel can be used in engines marked as compatible with B7 fuel.
Esso Supreme 25% Renewable Diesel contains our proprietary Synergy additive, designed to help clean vital parts of your engine, including your car’s fuel injectors. A cleaner engine means better performance.
Yes, this product contains our Esso Synergy additive and is part of the Esso Synergy fuels family. The Esso Synergy additive in Esso Supreme 25% Renewable Diesel provides the same great protection and cleaning power as the additive in our regular diesel to protect your engine.
Hydrotreated vegetable oil (HVO) is a renewable fuel that can be made from a variety of feedstocks including vegetable and animal oils and fats, or residue feedstocks (such as used cooking oil). It is carefully refined to become a high quality fuel component regardless of the original feedstock.Does Esso Supreme 25% Renewable Diesel contain palm oil?
Esso Supreme 25% Renewable Diesel does not contain palm oil. To supply the HVO used in Esso Supreme 25% Renewable Diesel, we purchase independently verified, RTFO compliant, waste and residue feedstock, such as waste or used cooking oil (UCO).
Esso Supreme 25% Renewable Diesel has all the great advantages that our customers have come to expect from high quality Esso fuels, but with the added benefit of 15% lower life cycle greenhouse gas (GHG) emissions compared with our regular diesel(1). However, it does cost more to manufacture because the renewable component of the diesel – the HVO - costs more than conventional diesel.
The petrol station owners who run Esso branded forecourts set their own prices for this product, however the HVO blend components of Esso Supreme 25% Renewable Diesel cost more than normal diesel so this product does cost more than regular diesel to manufacture. Consumers can therefore expect to pay a little more per litre for the renewable benefits of this fuel compared to conventional diesel.
Esso is piloting an alternative premium diesel containing our Synergy additive, that provides Retail customers with lower life cycle greenhouse gas emissions compared to our regular diesel(1), but with the same great protection. We think customers will be delighted with this new premium fuel, however we continue to sell Esso Supreme+ Diesel at most other Esso service stations. To find an Esso station providing Esso Supreme+ Diesel, please visit https://www.esso.co.uk/en-gb/find-station/
If the pilot is successful we will consider further expansion to make this product available elsewhere in our network.
Filling up your vehicle with Esso Supreme 25% Diesel is a great way you can make an immediate change. However don’t forget that there are other, simple steps you can take to help improve the fuel efficiency of your vehicle and help lower your fuel bills too! Follow these five steps to drive more efficiently:
- ensure your tyres are correctly inflated,
- accelerate and brake smoothly,
- remove the roof rack from your car when not in use,
- drive with the windows up, and
- remove excess weight from your vehicle

(2)Comparison is versus regular Esso Synergy Diesel. Esso Supreme 25% Renewable Diesel contains a minimum of 25% renewable diesel. Choosing Esso Supreme 25% Renewable Diesel instead of regular Esso Synergy Diesel results in 15% lower greenhouse gas emissions when comparing the emissions over the life cycle of each fuel. Fuels vary both in their total life cycle emissions (i.e. from production to use or “well to wheel”) and in how the emissions are distributed throughout that life cycle. The methodology for calculating life cycle emissions and emissions reduction follows that outlined in the Renewable Transport Fuel Obligations Order 2007 (SI 2007/3072) as amended (“RTFO”).

(3)Esso Supreme 25% Renewable Diesel has 15% lower life cycle greenhouse gas (GHG) emissions than our regular diesel (1). Calculations indicate that every 50 litres of Esso Supreme 25% Renewable Diesel used would, on average emit 133.7 kg of GHG emissions (expressed in CO2 equivalents, or CO2e) over the total lifecycle of that product. This compares with 50 litres of Esso Synergy regular diesel (B7), which would emit 159.1kg CO2e over its total lifecycle.
