why i asked as from 2008/9 a different dpf was fitted not requiring the fluid, so you car must one of the last ones requiring it, so the fluid up to 2008 is what you need.
holds 1.8 litres when empty
well its a 2009 1.6 econetic. it definitely has eolys. its on the service schedule and i also this week replaced my DPF, and its the one that needs eolys. i only know this as i phoned ford before ordering it off ebay. i believe the dpf you mentioned is a ceramic one? that doesn't need the eolys?
when i had the DPF replaced this week, the mechanic also said the eolys is empty, as it came up on his machine.
I'm pretty sure its the 176 I'm after.
thanks for the info though. i haven't been able to find out how much i needed.
