My service light is showing to change the oil now although it was only done 600 miles ago. Should I change it again and what brand/spec. Can I use a standard Castrol 5W-30 oil or is it more specific than that?
Can the service light be reset without a OB2 reader?

With a DPF it needs to be C1 specification - I used Millers Oils Trident Professional C1 5w-30 Fully Synthetic Engine Oil as Castrol wasn't available at the time in the correct spec. You don't need to reset via the OBD port, have a look in the WSM (link in the Wiki) for details of how to read & reset the oil level & service interval reset

Myself and I think Kot use this.

Yep C1 it is, and PETRONAS is good enough for Lewis Hamilton and co.
Opie oils were doing 20% off

600 miles is crazy though, who did the service reset?
being paranoid on fuel dilution I personally would change the oil so you know its done, do a search and get the sealy vacuum pump.

Service reset  2018 SE SDV8 4.4 Byron Blue

600 miles and needs another oil change. Thats mad even by ffrr standards. I’d be doing mine once every two or three weeks at that rate  2016 4.4 diesel

I don't mean to hi jack the thread but I have some some oil left over from changes I have done (I always get 10L but my Range Rover takes less), some Smith and Allan some Castrol and I was thinking of the offer from Opie for next time(Petronas).Can it be safely mixed if it's all C1 5-30W and fully synthetic. Or should I stop hoarding and take it to the tip, Geoff

It depends how long it takes the OP to do 600 miles...

Then there is a concern, either the oil level is not reading correctly, there is a sensor issue with the DPF regen or the last oil change was not reset correctly. Use this oil change as a baseline and monitor the service interval countdown. would also be helpful to do a full vehicle DTC read, if you have the capability.

DTC?

Diagnostic Trouble Code - 'fault code'.

Reset saying 16030 miles until service, so will keep an eye on it.
