Was looking for oil for my runabout and bought millers oil from cam skill XFS 5W40 Fully Synthetic only problem is its high performance oil, will it be too thin for the clio ?
The fact that it's a "high performance" oil has no bearing on how "thin" it is. The 40 is the important number - check your handbook, but I'd think a 5/40 should be fine for a Clio.
