CNG in a diamond

Compressed natural gas: natural gas or methane supplied as a gas by compression. On a vehicle, a CNG diamond means it can be filled with it.

What to do

Fill only from a nozzle whose diamond shows CNG if your vehicle's diamond shows CNG. CNG is not LPG: they are different gases with different identifiers.

What it looks like
The letters CNG in bold inside a diamond, black on white.
Where you find it
On the nozzle and dispenser of a CNG refuelling point; next to the gas filler of a vehicle that uses it and in its manual.
Kind
gaseous-type fuel
Set by
EN 16942:2016+A1:2021, identifier for gaseous-type fuels (a diamond), required by Directive 2014/94/EU Article 7; in the UK, SI 2019/421 Schedule 1, Part 3

Can my car use it?

“You will only need to match the label of your vehicle with the corresponding label on the fuel pump.”

“The European legislation requires the labels only for new vehicles placed on the market for the first time or registered as of 12 October 2018.”

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

  • UK law: CNG is 'natural gas or methane supplied as a gas by means of compression'.
  • The Commission counts natural gas, including biomethane, in compressed form among alternative fuels, and notes that 'in some cases CNG, LNG and LPG can be of 100% fossil origin'.
  • A vehicle that can also run on petrol carries both the diamond and the petrol circle (SI 2019/421, regulation 5(2)).

What it does not mean

CNG does not mean LNG (the same gas liquefied by cooling) or LPG (liquefied petroleum gas).
