European foreword
This document (FprCEN/TS 18227:2025) has been prepared by Technical Committee CEN/TC 19
“Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”,
the secretariat of which is held by NEN.
This document is currently submitted to the Vote on TS.
The purpose of this new document is to provide scope for fuels containing higher levels of oxygenates
(greater than 3,7 % (m/m) oxygen) as an enabler to help decarbonise the petrol-fuelled ICE light-duty
vehicle fleet in Europe.
At the time of publication of this document, the marking at the pump of this product is not in line with the
requirements of the European Fuel Quality Directive 98/70/EC [1], including its Amendments [2], [3],
[4], [5], [6], [7] and [13] and the Alternative Fuels Infrastructure Directive Regulation [17].
At the time of publication of this document, petrol with a higher ethanol content than 10 % (V/V) or
oxygen content higher than 3,7 % (m/m) is not allowed on the market in EU countries according to the
Fuel Quality Directive (FQD) [1], therefore revisions to the FQD in these aspects would be required to
enable E20 petrol to be sold in the European Union.

1 Scope
This document specifies requirements and test methods for E20 petrol marketed and delivered as such,
containing a minimum oxygen content of 3,7 % (m/m) and a maximum of 8,0 % (m/m). The fuel has a
maximum of 20,0 % (V/V) ethanol.
It is applicable to fuel for use in spark-ignition petrol-fuelled engines and vehicles.
This document is complementary to EN 228, which describes unleaded petrol containing an oxygen
content up to 3,7 % (m/m) and a maximum ethanol content of 10 % (V/V).
NOTE 1 For general petrol engine vehicle warranty, E20 petrol might not be suitable for all vehicles and it is
advised that the recommendations of the vehicle manufacturer are consulted before use. E20 petrol might need a
validation step to confirm the compatibility of the fuel with the vehicle, which for some existing engines might still
be needed.
NOTE 2 For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent
respectively the mass fraction, µ, and the volume fraction, φ.

4 Sampling
Samples shall be taken as described in EN ISO 3170 or EN ISO 3171 and/or in accordance with the
requirements of national standards or regulations for the sampling of unleaded petrol. The national
requirements shall be set out in detail or shall be referred to by reference in a national annex to this
document.
In view of the sensitivity of some of the test methods referred to in this document, particular attention
shall be paid to compliance with any guidance on sampling containers, which is included in the test
method standard.
It is essential that for sampling of unleaded petrol the containers used to take and store the samples
before testing are not contaminated, especially with lead and/or sulfur.
5 Pump marking
Information to be marked on dispensing pumps and nozzles used for delivering E20 petrol and the
identifier (shape, colour and size) shall be in accordance with EN 16942.
