The recommended oil, the AP-L 5W-30 spec is ACEA C2; PSA B71 2290. Meets the requirements of Fiat 9.55535.S1
The ECT C3 5W-30 spec is ACEA C3; API SN; MB Approval 229.51, 229.31; BMW LL-04; GM dexos2TM; Chrysler MS-11106
The ACEA website states
ACEA C2 Stable, stay-in-grade oil intended for use as catalyst compatible oil in vehicles with DPF and TWC in high performance car and light van diesel and gasoline engines designed to be capable of using low friction, low viscosity oils with a minimum HTHS viscosity of 2.9mPa.s. These oils will increase the DPF and TWC life and maintain the vehicles fuel economy. Warning: these oils are unsuitable for use in some engines. Consult owner manual or handbook if in doubt.
ACEA C3 Stable, stay-in-grade oil intended for use as catalyst compatible oil in vehicles with DPF and TWC in high performance car and light van diesel and gasoline engines, with a minimum HTHS viscosity of 3.5mPa.s. These oils will increase the DPF and TWC life. Warning: these oils are unsuitable for use in some engines. Consult owner manual or handbook if in doubt.
None of that means anything to me but I think it might be better to follow the advice on oil manufacturer website, yes?
