10W-40 is perfect for Australia. LR specified this for -10°C to 50°C climates.

On a very hot days I tended to find 5W-40 had very low oil pressure at idle, and on cold Perth mornings 15W-50 used to generate very high oil pressures until the engine warmed up.

I would think 15w-50 would cause drag when cold on the TD5, but if I remember correctly yours had quite high k's

Apologies to the OP as we are digressing.....[emoji3]

Yes - had over 450K at the time I tried the 15W-50. Originally to improve oil pressure over summer, but then found it was too thick for winter.

But this is idle chat filling in time.

IVe seen random missfires caused by a poorly handled injector harness having cracked wiring ad the injector plugs, might be worth a look.
