XTL

XTL in a square

Paraffinic diesel fuel: diesel made by synthesis or hydrotreatment rather than refined from crude oil in the usual way. On a vehicle, an XTL square means it can use paraffinic diesel.

What to do

Fill from an XTL nozzle only if the label by your filler flap or in your manual shows XTL. A diesel car labelled only B7 or B10 is not labelled for XTL.

What it looks like
The letters XTL in bold inside a square, black on white. There is no number.
Where you find it
On the nozzle and dispenser of a pump that sells it; next to the filler cap or flap and in the manual of a vehicle labelled for it.
Kind
diesel-type fuel
Set by
EN 16942:2016+A1:2021, identifier for diesel-type fuels (a square), required by Directive 2014/94/EU Article 7; in the UK, SI 2019/421 Schedule 1, Part 2

Can my car use it?

“The information inside the shape indicates the maximum biofuel content in the fuel that is recommended for use by the vehicle that is equipped with the new label.”

“Vehicle manufacturers do not recommend fitting the labels to older vehicles. Please contact your local dealer if you need advice on which fuel is recommended for use in your vehicle.”

Check your vehicle's manual or the label inside the filler flap. We do not say which makes or models can use this fuel.

Official guidance:

In detail

  • The Commission: 'the XTL stands for synthetic diesel and indicates that it is not derived from crude oil'.
  • The operators' guide adds that XTL is paraffinic diesel 'manufactured from renewable or fossil material' by synthesis or hydrotreatment, quite similar in composition to fossil diesel, to the fuel standard EN 15940, which allows up to 7% FAME to be blended in.
  • UK law: 'the symbol for paraffinic diesel fuel is "XTL"' (SI 2019/421, Schedule 1, Part 2, paragraph 2(g)).

What it does not mean

XTL is not a biodiesel percentage, and 'not derived from crude oil' does not by itself mean renewable: the operators' guide says it can be made from renewable or fossil material.
