I would never run 5w30 unless living in the artic. 10w40 summer= better cooling as it carry away heat better to the oil cooler and 10w 30 winter.got 300k on 1 engine petrol and 200k on a diesel and never did a thing to them other than 6k between oil changes.Some times that was every 6 weeks. fuel filter once a year and air filter once a year that is it. I really laugh at how you all have hgf and cooling issue with you cars. just un real.

5/30 is -30 to 35 so well within temp ranges we get in the uk, never above or below that?

5W-30 remember your 3.0L has a DpF and the it must be a C1 spec, this means low ash and helps the DpF not clog up to fast.
