Meanwhile back to the TLC on my Navara......
.....every year since I bought it I do an OIL SERVICE every year regardless.
Even though Nissan says 24 months or 24,000 miles I think it important to do it with a DPF vehicle

Did you know that it stops doing a DPF Regeneration IF it detects that the engine oil needs to be changed?
Dropping the oil is easy with the truck over my pit.
But it's been 2 years since changed the oil filter. The main stealer did it last year......
On the NP300 the oil filter is on the front of the engine which is accessed from below after removing these TWO under trays
Another reminder of why I hate and don't trust Main Stealers.
There should be 4 plastic body clips locking the bottom of the bumper to this big under tray
All missing no wonder my bumper lower edge was floppy

Under trays off and there's the filter. Sandwiched between the bottom hose, anti-roll bar and power steering hose
Anyway bit of basic spannering saw the job completed in my nice warm workshop.
