Hi all

Just bought this car, 05 plate though I collect it last week put first batch of 30% biodiesel .
run succesfully? I know that Citroen allow a mix of 70/30.
I understand that it rots rubber pipes, any concerns with this?
Could I put more percentage biodiasel with out the feel of damaging car in long term?
Has anyone else got a C4 what are you doing
Thank you for responses!

Hi DannyEnglish,
I purchased a demo C4 about a year ago and tried B20 to start with but shortly moved to B100. My C4 had only consumed 1 tank of diesel so I have had no problems with fuel filters blocking up due to a build up of gunge from prolonged use of Diesel. No problems whatsoever with 15,000km of driving on mostly B100.

There are others on this forum with C4s and C5s so do some more research. Also the C4 uses the same engine as peugot?? 307 1.6.

Enjoy. Its a wonderful car.
