**Comparison is versus regular Esso Synergy Diesel. Esso Ethos+™ 25% Renewable Diesel contains a minimum of 25% renewable diesel. Choosing Esso Ethos+™ 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”).

[H1] Frequently Asked Questions

[H2] Fuel

Ethanol is a renewable fuel produced from plant materials.

E10 is the standard (95 octane) regular petrol sold at all forecourts. It contains up to 10% renewable ethanol, a low carbon fuel that can be blended to reduce the amount of fossil fuel in petrol.

The government mandated in September 2021 the switch to E10 petrol to help reduce carbon dioxide (CO2) emissions associated with petrol vehicles. E10 fuel is already widely used around the world.

E5 petrol contains up to 5% ethanol by volume and E10 contains up to 10% by volume. All Esso's Synergy fuels contain additives to help clean, protect and enhance your car's engine, however Esso's Synergy Supreme+ 99 E5 fuel contains a double dose of additive. Esso Synergy Supreme+ 99 contains up to 5% ethanol.

All petrol cars manufactured after 2011 can use E10. If you are unsure you can check using the government E10 compatibility checker , which covers cars, motorbikes and mopeds. If your specific vehicle is not listed, consult your manual, or contact your vehicle manufacturer. If in doubt, the government’s recommendation is to continue using E5 petrol (Esso Synergy Supreme+ 99).

Check the government's E10 compatibility checker to be sure, but it is expected that a number of older cars, classic cars and some mopeds are incompatible with E10 petrol. If in doubt use the E5 grade, Esso Synergy Supreme+ 99 which is available at most sites.

Esso Synergy Supreme+ 99 which is E5 is unchanged and available at most Esso service stations despite E10 being introduced.

Yes you can, Esso Synergy Supreme+ 99 is available at most Esso sites, please check here for availability.

Yes, E10 petrol is still available at all of our sites, and E5 Esso Synergy Supreme+ 99 remains available at most Esso service stations despite E10 being introduced - please check here for availability.

All fuels are clearly labelled at the pump and on the nozzle you'll see E5 or E10 clearly shown.

If your vehicle is compatible with E10 petrol it is perfectly safe to use E5 or E10 fuel, and to use a different fuel subsequently, e.g. if you use E5 on one fill and then E10 on the next.

Using a single tank of E10 petrol in a vehicle that is not compatible should not be a major problem. Just make sure you fill up with E5 petrol next time. Unlike putting petrol into a diesel engine, you shouldn’t need to drain the tank, see https://www.gov.uk/guidance/e10-petrol-explained for details.

https://www.gov.uk/guidance/e10-petrol-explained

Some other petrol-powered equipment may not be compatible with E10 petrol including boats, petrol-powered garden equipment or machinery, such as lawnmowers and chainsaws. Owners and operators should check their manual or ask the manufacturer or dealer before using E10. If in doubt, the government’s recommendation is to continue using E5 petrol (Esso Synergy Supreme+ 99).

From September 2023 our Synergy Supreme * 99 transitioned to contain up to a maximum of
5% ethanol at all Esso pumps irrespective of which part of the country they are located. The
labelling at our pumps will remain as E5 for Synergy Supreme * 99 unleaded.

The octane rating of petrol is a measure of its resistance to knock, with higher octanes more resistant to knock. Petrol engines work by compressing air and fuel, then igniting the mixture with a spark. Certain engine conditions can cause all or part of the mixture to ignite on its own without the spark, creating what’s called “knock” in your engine. Fuels can be blended to meet different octane ratings at the refinery or fuel terminal.
The majority of today’s petrol vehicles are designed to run on regular octane fuel (95). However, using higher octane fuel than the minimum required can benefit fuel economy, power and acceleration even in vehicles calling for regular fuel. Engine design features like higher compression ratios and forced air induction (e.g. turbochargers or superchargers) can make engines more responsive to octane. The benefits achievable with higher octane depend not only on hardware design but also on the car’s calibration and the user’s driving style.

Our Synergy regular petrol has 95 octane, while our Synergy Supreme+ 99 is a 99 octane petrol.

Our Supreme+99 formulation actually now contains more than 2x the detergent molecules of our regular unleaded grade.  The cleaning benefits of fuels are not directly correlated with the concentration of cleaning molecules in the fuel.  Testing shows our new Esso Synergy Supreme+ 99 unleaded formulation helps keep your engine 3x cleaner than Esso Synergy Unleaded 95 and Esso Synergy ™ technology now also features three distinct detergent ingredients.  Esso Supreme+ 99 protects your engine against deposits, corrosion and wear.*

[H2] Ethos+™ 25%

Esso Ethos+™ 25% renewable diesel is the new name for Esso Supreme 25% Renewable Diesel. Esso Ethos+™ 25% Renewable Diesel is a high quality diesel fuel made with a minimum of 25% premium renewable content - hydrotreated vegetable oil (HVO). The HVO we use is made from used cooking oil that is refined into a high quality fuel component and blended with conventional diesel and our proprietary Esso Synergy additive. It is intended for use in the same applications as conventional diesel. Esso Ethos+™ 25% Renewable Diesel has 15% lower life cycle greenhouse gas (GHG) emissions than our regular diesel (1).

Esso plans to play a leading role in the energy transition by providing products to help customers reduce their emissions. Research also shows growing customer demand for lower GHG emission fuels, and so we are choosing to trial an alternative premium diesel containing Synergy additive. This alternative diesel offers the same great protection as our regular diesel, but also provides potentially lower life cycle greenhouse gas emissions. By trialling Esso Ethos+™ 25% Renewable Diesel we are offering customers an additional choice for their fuelling options that requires no change to their vehicle – it’s an immediate ‘drop-in’ solution.

The product is available at 35 stations in South East England. Check availability here: https://www.esso.co.uk/en-gb/find-station/

We will continue to explore opportunities to expand the network further and will announce new sites as and when the product becomes available in them https://www.esso.co.uk/en-gb/find-station/

Esso Ethos+™ 25% Renewable Diesel is a drop-in replacement for conventional diesel that meets EN590 specification requirements and is suitable for all diesel engines. Esso Ethos+™ 25% Renewable Diesel does not contain fatty acid methyl ester (FAME).

Renewable fuels are produced from a renewable energy source. Examples are fuels made from biomass such as wood or crop waste, from oil extracted from plants, or from previously used materials (such as used cooking oil, or animal fats). In the case of renewable diesel, those renewable energy sources are carefully refined to become a high quality fuel component.

Esso Ethos™ Renewable Diesel is our branded renewable diesel product. Renewable Diesel is a recognized term for what is often referred to HVO or HVO100 (shorthand for hydrotreated vegetable oil). “Ethos” reflects our belief that our renewable diesel product solution is an important forward-looking addition to our diesel portfolio, combining the quality and performance of Esso’s diesel heritage with the added potential for lifecycle greenhouse gas emissions reduction.The latest addition to our diesel family is formulated with a minimum of 25% Esso Ethos™ Renewable Diesel. The renewable content helps reduce the life cycle GHG emissions by 15% when compared to our regular diesel (1). The “+” in Esso Ethos+™ 25% Renewable Diesel refers to the formulation of this product with our Esso Synergy additive technology. Esso Ethos+™ offers the same great protection and cleaning power as our regular diesel to protect your engine.

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 Ethos+™ 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)

Life cycle greenhouse gas (GHG) emissions calculations consider all emissions associated with the fuel, including the extraction or sourcing of the raw materials, its production, distribution and use. Lifecycle greenhouse gas emissions are also often referred to as the carbon intensity (CI) of fuel. Such a calculation provides a useful way of comparing the GHG emission benefits of different products, helping customers better understand the choices they are making based on the full impact of that product.
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 Ethos+™ 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 Ethos+™ 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 159.1 kg CO2e over its total lifecycle.

Esso Ethos+™ 25% Renewable Diesel is a high quality diesel fuel, which includes a premium renewable ingredient to help deliver 15% lower life cycle greenhouse gas emissions (1) when compared to our regular diesel. It is formulated with care to ensure that it delivers the same great protection and cleaning power for your engine. It is a drop-in fuel, meaning it is suitable for use in all diesel engines marked as compatible with B7 fuel – simply drive your diesel vehicle to one of the 20 service stations taking part in the trial and fill-up with Esso Ethos+™ 25% Renewable Diesel.

Esso Ethos+™ 25% Renewable Diesel meets BS EN590 specifications, the same as both regular and premium conventional diesels. It is called a ‘drop-in’ fuel as it is suitable for all diesel engines, and can be used interchangeably with regular or premium diesel.

Esso Ethos+™ 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 Ethos+™ 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 Ethos+™ 25% Renewable Diesel can be used in engines marked as compatible with B7 fuel.

Esso Ethos+™ 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. The Esso Synergy additive in Esso Ethos+™ 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.

Esso Ethos+™ 25% Renewable Diesel does not contain palm oil. To supply the HVO used in Esso Ethos+™ 25% Renewable Diesel, we purchase independently verified, RTFO compliant, waste and residue feedstock, such as waste or used cooking oil (UCO).

Esso Ethos+™ 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 gree

[H2] What’s in our Synergy regular diesel?
Our fuel engineers spend hours and hours testing different ingredients and formulas, because they know the smallest change can make a difference. Like the molecules in our regular Synergy diesel that have been specially designed to help clean vital parts of your engine (like your car’s fuel injectors) and help look after your engine. You may have heard that nasty engine deposits can build up in your engine over time which prevent your car from performing at its best and can reduce your fuel economy. In fact, when we tested Synergy diesel on everyday cars it helped improve fuel economy by an average of 1.8%.***

[IMG: Two circles (plain and patterned) with the two kinds of diesel, Diesel and Supreme+ diesel]

[H2] What’s in our Synergy Supreme+ premium diesel?
Our Synergy Supreme+ Diesel has double the detergent additive than our regular diesel. This means it gives your engine a deeper clean, to better remove nasty deposits and improve the amount of power and responsiveness you get. There are other benefits to Supreme+, including less wear and tear, a clean fuel injector, better protection from corrosion, and less chance of clogging. It also helps the fuel burn more efficiently so you get better fuel economy†.

[H2] Frequently Asked Questions

Ethanol is a renewable fuel produced from plant materials.

E10 is the standard (95 octane) regular petrol sold at all forecourts. It contains up to 10% renewable ethanol, a low carbon fuel that can be blended to reduce the amount of fossil fuel in petrol.

The government mandated in September 2021 the switch to E10 petrol to help reduce carbon dioxide (CO2) emissions associated with petrol vehicles. E10 fuel is already widely used around the world.

E5 petrol contains up to 5% ethanol by volume and E10 contains up to 10% by volume. All Esso's Synergy fuels contain additives to help clean, protect and enhance your car's engine, however Esso's Synergy Supreme+ 99 E5 fuel contains a double dose of additive. Esso Synergy Supreme+ 99 contains up to 5% ethanol.

All petrol cars manufactured after 2011 can use E10. If you are unsure you can check using the government E10 compatibility checker, which covers cars, motorbikes and mopeds. If your specific vehicle is not listed, consult your manual, or contact your vehicle manufacturer. If in doubt, the government’s recommendation is to continue using E5 petrol (Esso Synergy Supreme+ 99).

Check the government's E10 compatibility checker to be sure, but it is expected that a number of older cars, classic cars and some mopeds are incompatible with E10 petrol. If in doubt use the E5 grade, Esso Synergy Supreme+ 99 which is available at most sites.

Esso Synergy Supreme+ 99 which is E5 will be unchanged and available at most Esso service stations now E10 is introduced.

The octane rating of petrol is a measure of its resistance to knock, with higher octanes more resistant to knock. Petrol engines work by compressing air and fuel, then igniting the mixture with a spark. Certain engine conditions can cause all or part of the mixture to ignite on its own without the spark, creating what’s called “knock” in your engine. Fuels can be blended to meet different octane ratings at the refinery or fuel terminal.
The majority of today’s petrol vehicles are designed to run on regular octane fuel (95). However, using higher octane fuel than the minimum required can benefit fuel economy, power and acceleration even in vehicles calling for regular fuel. Engine design features like higher compression ratios and forced air induction (e.g. turbochargers or superchargers) can make engines more responsive to octane. The benefits achievable with higher octane depend not only on hardware design but also on the car’s calibration and the user’s driving style.

Our Synergy regular petrol has 95 octane, while our Synergy Supreme+ 99 is a 99 octane petrol.

Our Supreme+99 formulation actually now contains more than 2x the detergent molecules of our regular unleaded grade.  The cleaning benefits of fuels are not directly correlated with the concentration of cleaning molecules in the fuel.  Testing shows our new Esso Synergy Supreme+ 99 unleaded formulation helps keep your engine 3x cleaner than Esso Synergy Unleaded 95 and Esso Synergy ™ technology now also features three distinct detergent ingredients.  Esso Supreme+ 99 protects your engine against deposits, corrosion and wear.*

*Based on Esso Synergy Supreme+ 99 petrol compared to Esso Synergy regular petrol in port fuel injected engines. Esso Synergy Supreme+ 99 Unleaded Petrol claims based on (1) internal or third party vehicle engine testing; and /or (2) government publications; and/or (3) industry or scientific literature. Benefits may vary depending on factors such as engine type, driving style and fuel previously used. Concentration and availability of our proprietary additive package may vary due to factors beyond our control. Esso Synergy Supreme+ 99 Unleaded Petrol has a higher additive treat rate, compared to Esso Synergy Unleaded Petrol and contains more friction modifier. Esso Synergy Supreme+ 99 Unleaded is available at selected Esso branded service stations only.
**Comparison is versus regular Esso Synergy Diesel. Esso Ethos+™ 25% Renewable Diesel contains a minimum of 25% renewable diesel. Choosing Esso Ethos+™ 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”). Actual results may vary.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?

Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Esso UK provides a masterclass in how a legacy energy giant can navigate the ‘green’ energy transition without drowning in fluff. By grounding every environmental claim in specific RTFO formulas and technical specifications, the site manages to keep its BS score in the low 20s. It is a substance-first platform where marketing language is used only as a wrapper for technical and regulatory data.

To further reduce the BS score, Esso should: 1. Implement Person schema for lead fuel engineers to put names behind the research claims. 2. Replace unverified ‘review counts’ with direct API-integrated links to third-party review platforms. 3. Add sameAs property links to the Organization schema to connect the site to official regulatory filings or verified social profiles. 4. Convert the ‘internal engine testing’ footnotes into downloadable whitepapers or linked summary reports to provide a clear proof path for the ‘3x cleaner’ claim.

The site perfectly matches the Energy and Utilities category, specifically focusing on fuel retail and the ‘energy transition’ through renewable diesel trials and GHG emission disclosures. The content centers on fuel specifications, chemistry, and regulatory compliance (EN590, RTFO), confirming its role as a primary energy provider.

“The score of 24 is driven largely by the high substance-to-fluff ratio in the Fuels and FAQ pages, which offset the minor template penalties in the Loyalty section.
