6000 mile oil change intervals, no?

Flatulentoldgoat

Can't remember but I read somewhere that an oil filter is only good for 4-6k miles. Well, my friends van is at 6k miles and he mostly does motorway driving with a very light load. It's a Nissan NV200 with the diesel engine.

I reckon 10-12k miles sounds more reasonable. What's the verdict?

For the record I think changing the filter and not the oil as well is utterly pointless so for arguments sake do both at 12.

What does the Nissan service schedule recommend?

There was a thread on this a while back, unfortunately it's fallen all the way down to page 2.......................oh well.

Too long, probably, for the sake of lower ownership costs and never mind longevity.

4-6k is overkill these days, otoh.
I'd be going around 10k or so - it also makes it easy to keep track of when it's due, if you align it with an odometer roundieth.

Fair points, where I'm confused is the book of words appear to state X miles or 12 months, whichever is sooner.

I have a strange feeling that oil sat in the sump doesn't go 'off' after 12 months.

It does.

Maybe not after precisely 366 days, any more than it does after X+1 miles, but it certainly does over time. The whole point of periodic changes is to pre-empt that deterioration.

My 7K Mile Ford Transit Courier Ecoboost 1.0 has 18K Service intervals !  Although it does say that oil changes may be needed more frequently than that.

The " change engine oil " warning message came on the other day, so gonna change oil and filter this coming week.

Use it for courier work, lot of stopping/starting so has a harder life than the average. Im planning on changing the oil every 6 or 7 K to hopefully keep it sweet.

I think that a lot of vehicles that have high oil change periods ,18k miles etc use higher quality oil ,i know my  Mercedes Sprinter van was 18 thousand miles but i am sure the Merc dealer used fully synthetic oil ,as it was under under extended warranty the company i worked for had an agreement where it was dealer serviced /maintained .

That's really not a good idea, but your choice.
Oil = cheap
Engines = Expensive

For the sake of £50 its not worth the risk, especially with a car with a timing chain.
I've worked in Motorsport for years. Trust me on this.

Depends on the oil you put in. I don't use anything but name-brand semi or full synth.

~10k intervals have been standard since the 90s, on engines that have gained a reputation for outlasting the car they're in. Personally, I think it's a comfortable compromise interval.

Obviously, stuff that's used less frequently than a daily-driver, or gets a lot of short-journey use should probably be changed on a time-based interval.

I have to disagree with you on this.  Yes, an oil change is peanuts in comparison with a dead engine.  But Adrian is advocating changing the oil more regularly than the service schedule specifies.  And for "normal" operating conditions, and with a reasonable quality oil, 10K miles is, I would say, perfectly reasonable.  6000 miles was recommended when I was young, but that was 30-odd years ago - oils have had a lot of development money spent on them in the interim.

You say you've worked in motorsport - I'm perfectly willing to accept that more frequent changes are the norm there, but that would hardly be described as "normal operating conditions".  I would imagine the engines take a hell of thrashing and run a lot hotter than your average family saloon.
