Practical Information -> Compatibility of fuels for Your Citroen C5 SUV 2020

Practical information  
When a petrol filler nozzle is introduced into  
the fuel filler neck of a Diesel vehicle, it comes  
into contact with the flap. The system remains  
closed and prevents filling.  
Compatibility of fuels  
The only fuel additives authorised for use  
are those that meet the B715001 (petrol)  
or B715000 (Diesel) standards.  
Do not persist but introduce a Diesel type  
filler nozzle.  
Diesel at low temperature  
Petrol fuels conforming to the EN228 standard  
containing up to 5% and 10% ethanol  
respectively.  
At temperatures below 0°C (+32 °F), the  
formation of paraffins in summer-type Diesel  
fuels could prevent the engine from operating  
correctly. In these temperature conditions, use  
winter-type Diesel fuel and keep the fuel tank  
more than 50% full.  
It remains possible to use a fuel can to fill  
the tank.  
Travelling abroad  
Diesel fuels conforming to the EN590,  
EN16734 and EN16709 standards respectively  
and containing up to 7%, 10%, 20% and 30%  
fatty acid methyl ester respectively. The use of  
B20 or B30 fuels, even occasionally, imposes  
special maintenance conditions referred to as  
"Arduous conditions".  
At temperatures below -15°C (+5 °F) to avoid  
problems starting, it is best to park the vehicle  
under shelter (heated garage).  
As Diesel fuel pump nozzles may be  
different in other countries, the presence  
of the misfuel prevention device may make  
refuelling impossible.  
Not all Diesel vehicles are fitted with  
misfuel protection, so before travelling  
abroad, we recommend that you check  
with a CITROËN dealer whether your  
vehicle is suitable for the fuel pumps in the  
country in which you intend to travel.  
Travelling abroad  
Certain fuels could damage your vehicle's  
engine.  
In certain countries, the use of a particular  
fuel may be required (specific octane  
rating, specific trade name, etc.) to ensure  
correct operation of the engine.  
7
Paraffinic Diesel fuel conforming to the  
EN15940 standard.  
For all additional information, consult a dealer.  
The use of any other type of (bio) fuel  
(vegetable or animal oils, pure or diluted,  
domestic fuel, etc.) is strictly prohibited  
(risk of damage to the engine and fuel  
system).
