I really wasn't sure where to post this as it's a bit of a mish mash of stuff :serious:


So I've owned my Navara NP300 for a little over 3 weeks now and I must say it's absolutely brilliant. Already been on one camping trip and it just consumed all the camping gear we needed with a ton of room to spare. Mine benefits from a Pegasus4x4 canopy with side windows and central locking which is just ace.


My previous car was a 2016 Nissan Pulsar Tekna which was a fabulous small family car - a much under estimated vehicle. Owned from new and sold with a little over 14k on the clock .... I don't drive much.


First impressions of the Navara were .... wow, it's huge!! It's a bit bouncy around the corners, the gearbox / gearchange isn't quite as slick as the Pulsar, pulling out at junctions / onto roundabouts takes a little more time and thought. You get a great view sat up high, it's a very leisurely drive ... can't exactly make a quick getaway in it. It's an altogether different driving experience for sure.



I can't really say much about fuel consumption just yet - been a mixture of long and short journeys and it's showing 37mpg at the moment.


I've read plenty of threads on here about all sorts but was interested about the chassis and rust - mine doesn't seem to bad. But I did notice the amount of areas where mud and crud can collect so spent an hour washing this out with a hose pipe - rear mudflaps, up in the rear wheel arches etc. Can't imagine wet / damp mud sat there for months will do it any good.


I plan on changing oil / oil filter asap just because two years seems a long time between services, but got rained off last weekend. One thing I wasn't sure on is what kind of bolt head is used for the oil drain plug, am sure I saw a YouTube video and it wasn't a standard socket? Anyone help me please?



If I can I might take a look at the brake discs / pads, mines a 2016.5 Navara with 25k on the clock and not sure how long these should really last for. Obviously it all depends on driving I suppose.


The only thing I don't like so far is having to leave it on the drive, I've always put my car in the garage as I don't need a car for work. But at a bit over 5m in length it's just a bit to big ... oh well, there's worse things I suppose.


Overall, very happy with my new vehicle :smile2:

Moved to Navara chat.

The general rule is to change the oil at service intervals, if you don't do the miles, change oil annually.

Pretty sure it uses the Renault key for the sump plug. Amazon do a set of 5 sump plug keys for £7....

I too change my oil every 8 -10k.... 2 years is way too long with a modern Diesel engine.... yes the oil itself is well capable of lasting the 2 years but with many interrupted or incomplete DPF regeneration cycles, the oil is contaminated with unburned fuel. It is very wise to change annually if you are a low mileage user with lots of start stops. It’s the hardest mileage a car can do. I do around 10-12 k yearly all local trips no motorways ever.... so I drop mine around 8k which seems mid way to the next main service.


My brakes were totally finished at 17k miles. Being auto and with the above style of driving I cannot see them lasting any longer next time either!

If yours has been a motorway cruiser then they may have lots of life left... well worth checking them and the width of your disks....mine were down to 25mm which is almost at the point of failure... just slip a wheel off and have a look.

The length is surprising! I think mine is longer than my old Ford transit custom LWB 6 seat double cab.... not many garages can accommodate them.

Hope it continues to please....safe driving. :)

Hi there fellow leeds dweller, where abouts?are you im in seacroft!(killingbeck side)
I do around 15k a year (50/50 motorway / A roads and generally change my oil at the beginning of summer then again at the back end of summer! But shes done 160k so shes a senior citizen now lol and i get my oil free from work :)
Yea they are long trucks but fortunately ive a 40 foot drive so it swallows it up no problem.

Some on here reckon 8 to 10k is way too long and change the oil every 2 to 3k.
Have you shares in an oil company or something . Nissans 18k is sooner than needed in reality with modern fully synthetic oils. I went on a Mercedes course last year for an industrial engine they were adamant that changing oil sooner than the service interval caused more problems than it going longer as their intervals already carry a safety margin. We use oil testing routinely on the farm as CAT tell us when the oils need changing on their engines and transmissions as there is no fixed service intervals its not unusual to have 800 hr service intervals with these type of engines(Worked hard) equivalent to 30k mile in a pick up.
Im afraid the old changing the oil at shorter intervals is very retro .

"they were adamant that changing oil sooner than the service interval caused more problems "


Can't believe that for a second, on what grounds????

This is just a feeling I have, but you may struggle to convince people of that...

When I say "people", that may include Mercedes.

Ah well ,they have more faith in modern lubricants, It came a bit out of the blue ,along with not cleaning air filters till the warning comes on . Guess it helps if here it direct from them.
The damage caused by running an engine with an empty filter is deemed more detrimental than any perceived problems with extended oil changes. Are you suggesting Mercedes would sanction longer change cycles just to wear out their engines. I think people struggle to get their heads around how much better modern fully Synth oils than what they were used to in their youth. In theory modern oils could do the whole service life of a vehicle if not for contamination, and thats where routine oil testing comes in for a 1/3 of the cost of an oil change you can know pretty much what evers going on in your engine . Guess many of the herd who changed their timing chains out of a belief they all fail would have been more enlightened by a £25 test to check the oil than the cost of replacement. You pick up so much early .
Oh and the answer to the air filters is ! the dust acts as an extra filter medium and only needs putting right when the air flow drops below the engines need.

So in short, it's bad practice of preparation of the filter in this case - not the oil change itself. Nice back-track!

I won't get into a debate, but engine oils also clean and cool, (two factors which often get missed); dirty oil cannot do this efficiently.

Testing of oils was initially introduced many years ago, and was intended as a preventative maintenance measure with regard to the engine, not the life/condition of the oil, which was changed at interval. Picking up higher levels than expected of one type of material during a lab test on an oil sample may indicate need for attention in a certain location, for example.

I can imagine the salesman pitch at this Mercedes marketing event, common undertone of "buy our engines, you don't even need to change any filters or oil" vibe. Absolute spiel. Fact is, they wear the same as any other two metal surfaces, passing closely, protected by a film of (clean!!) oil. They're trying to flog engines/machines, and in the process, making sure you learn how to nicely wear them so they don't last too long. And since you mention it, yes, I would suggest that Mercedes (and every single other producer of absolutely anything) would concern themselves with profit. After all, it's the same reason everyone's Nav chassis rots so fast.

Synthetic oil or not, makes no odds, it gets dirty. End of.

Changing your oil does good, people! Not bad.

Read my post more carefully as I didnt mention sales people anywhere,dont assume. Testing of oil picks up the contaminants that you say would be released by the cleaning action the very reason every vehicle on the farm is checked on a rolling cycle. Still I guess Mercedes and FTP are renowned there reliability and longevity for some reason. I am all for changing oils at the correct intervals but do not understand the mentality of changing them sooner as I merely pointed out there is no point and the perceived benefits may be out weighed by the down sides and not least expense . Money spent on oil samples is better spent in my view as you pick up so many things that may be brewing. Still I guess we may be a bit more careful with a 40k engine in a forager.

Still beats me why were still in essence using paper oil filters?
I mean come on ive seen filters so good (albeit expensive) that you can filter sewage water and make it clean enough to drink! so surley with the price of oil constantly going up its time to implement some of this technology jnto automotive oil filters so that we can genuinely have "lubrication for life" oil

@popsdosh Ah, c'mon now, you were at a sales event, free Mercedes mugs and pens!
@gfromleeds I think it's down to pressure. I know the type of fine filters you speak of, but I am pretty sure it takes an enormous pressure to overcome just how fine they are. That being said, "they" could just build a more reliable, higher pressure oil system?!

Did you get your servicing done?

For various reasons I only managed to get this done yesterday. Fairly straightforward, the oil filter was a challenge, just so little room to get the 27mm socket on and moving. But got there in the end. Only minor cockup was me spilling some oil when filling it back up which promptly ran over various belts and bits of the engine and onto the drive. So then spent a while trying to clean that up.


Next time it will be a much smoother job :smile2:

Ah not too far then
We've got a few members in and around leeds now so thinking in the near future setting up a "meet" possibly at squires cafe bar near the A1 jct42
Is that something you'd be up for?
