what grade of oil should I be running in a Nissan navara stx

This answer was rated:

what grade of oil should I be running in a Nissan navara stx 2006 model 2wd presently the service station put in 15w 40

Hello, I hope the following is of assistance.

The recommended oil grade for this engine is 5W-30. If the vehicle has a DPF then 15W-40 certainly shouldn't be used, this oil is only recommended in this engine if there is no DPF fitted and the engine is subjected to extremely cold conditions.

I hope this helps but if I can assist further let me know and I'll reply as soon as I'm able to.

Best wishes,

Sean.

thank you for the lead so far, this model 2006 as far as I know dosnt have a dpf, so are you saying 15w-40 is ok, I had seen where a directive from Nissan suggested 15-w 40 shouldn't be used, that 10w-40 was the better oil to go to as it didn't wear certain components to the same extent as the 15w-40, in saying that also I take it that 5w-30 is ok whether it has dpf or not , I would be pleased if you can get back to me as soon as possible many thanks

Hello again,
the recommended oil is 5W-30, regardless of a DPF, allother grades are only advised for extreme climate conditions not seen in the UK.
I hope this clarifies things for you.
Best wishes,
Sean.
