Hi,
What is your opinion on the most effective FBC? I have a 59 plate Mazda 1.6d which has the Ford PSA engine and uses eolys fluid. I believe this is cerium oxide. Is iron oxide or platinum oxide a more effective FBC? I'm not sure if this PSA engine also uses post injection to heat the exhaust gas, would you know?
Regards,

Thank you for your questions. I believe the most effective FBC is cerium oxide because it is a catalyst for soot removal by both oxygen and nitrogen dioxide gases in the exhaust. This is not true for iron and platinum so they are less effective. Over the years there have been 3 generations of Eolys fluid which have used both cerium and iron chemistry. Your car uses Eolys 176 which contains both iron and cerium oxide. The PSA literature suggests your car does have post-combustion fuel injection but I don’t know for certain.
