Clio 1.4 16v oil grade?

[potter88]

Anybody know the preferential oil grade for these engines and whether part or fully synthetic?

I stay in south africa so its a hot climate, been running castrol 10w 40 for 12 years with out any problems... briefly tried 5w 30 which made it run very tappy... but it is recommended for the colder climates... so depends... cant go wrong with fully synthetic 10w 40 though

A UK X65 vehicle with a K4M will be fully synthetic 5w/40 to RN0700 or RN0710.
