This came up on my fb site yesterday. Member bought a ZD and changed the filter straight away under our instruction. Oil hadn't been changed in 40,000km.

OOHHH Oh Oh.

I have been changing every 5000km and initially I used to only do the filter every 10,000 as suggested by my Nissan dealer's service center as that is what they did. But then I started cutting the filters open to see what was in there. Well about three or four years ago I found a few bits of silver metal flakes in the filter so I figured bugger it, I will do oil and filter every 5000 and cut the filter open to inspect, just to give some prior warning if something were to crap itself.

 

I change oil and filter every 10000km, catch can and EGR blocked.

 

I follow the 5000K mark or 1 year if the car sits longer unused. My use of the car belongs to the severe driving conditions (mixed short trips, stop and go, offroad and long trips as well). Oil is cheap compared to other components. I used BP Visco 5000 and recently changed to Mobil 1 Delvac both in 5W-40. I managed to find someone who does the oil analysis in my country but almost every attempt was fail up to the recent research that seems promising.

In Australia, severe conditions are 5,000km or 6 months. I do less than 3,000km a year but refuse to believe the oil will go "off" in 6 months when the car is parked in the garage not going anywhere. I change my oil every 12 months using a good quality full synthetic.

BTW mine's a CRD not a DI.

 

can any one let me know if i change the oil at 7500, but 12 months will be OK. i was told in Europe many car company let the oil change to 15,000k / 12 months? i am using 5-40 sime syn oil. but i am thinking to change to nulon 10-40 full syn oil in next change.

 

Yes that is ok.

I'm always on the 5,000km mark. I service myself so it's not really expensive to do and only takes an hour max

 

My comment that the other thread was for TD42 only was because the original poster has a TD42, and in regards to bypass filtration and oil sampling, the only info I know is for the TD42. I would be reluctant to make any suggestions to anyone with a ZD30, as I do not know much about them. I did not want my comments taken out of context.

I think having a separate thread for 3 litre engines is certainly valid, as I would guess that the results of oil sampling etc could be very different. Even between the ZD30 and the CRD you could very easily find quite different results. If anyone has used a bypass filtration set-up on a 3 litre, or done any oil sampling the results could be very interesting.

 

Every 10,000km or once a year what ever comes first.... Since fitting EGR block the oil stays MUCH cleaner as we all know.

 

Damn, Ive got 500k to go and I will be doing my 3rd in less than a year :shock:.

 

Yearly usually comes up before 10,000km here...

I need to get out more. :lol:

 

All those regular services... and How is your motor going?

 

Servicing has nothing to do with it , mine was serviced every 5,000k right up until it grenaded :headwall:, now I've doubled the K's mainly on 10,000k services.

 

O yes.... Bloody ZD30's

 

So... what is the point of 5000km services if there going to grenade anyway?

Since i was old enough to spin a spanner it has always been 10k services... Well untill i stepped into the TD Patrol world... Chit my old TB GQ loved it 20k services. :lol:

 

Currently doing 10,000 km a month. Service every 3 weeks, 7500km, with oil and filter. Air filter every 3rd service. Fuel filter is aftermarket every 5 services.

 

10,000km a month? That is crazy... I don't even do that a year.. :lol:

Are they work related km's?

 

So what do people do when they go on extended long distance trips all over the country? For instance, I'm in Melbourne and my sister lives in Townsville. I'd love to take the Patrol up there one day, but that's a 5,500km round trip excluding sightseeing, so if I was doing 5,000km services I'd have to do an oil change along the way...?

That's the biggest issue I have with Australian service intervals. It doesn't make sense to me considering the operating conditions of 99% of the country's vehicles.

I can only comment based on my own experience and knowledge. AFAIK ZD30 first appeared in South Africa in 2001 in D22. It was launched with 7,500km service intervals because at that time the sulphur content of diesel in the country was 500ppm. A few years later, 50ppm became generally available and service intervals were increased to 15,000km as a result.

Operating conditions in South Africa are very similar to Australia apart from the longer distances. But 80% of South Africa is above 1,200m AMSL and speed limits are higher (and often ignored). So people can sit at 140km/h towing a 2ton trailer at an ambient of 35C and altitude of 1,200m.

Considering the good quality of diesel fuel (10ppm) in Australia, I find it very difficult to understand the justification of servicing a ZD30 every 10,000km, let alone 5,000km. I still stand by what I said earlier. Manufacturers in Australia are gouging motorists by over servicing their vehicles. It's nothing more than a money making scheme.

 

So what do people do when they go on extended long distance trips all over the country?

I take oil and filters and several plastic buckets. I stop and change oil in truck bays or gravel pits. Pour oil back into the containers and drop off at a Council facility or Super Cheap Auto when I buy my next lot of oil. It is a pain but for long distance travel, I figure it is better to do it that way then I am self sufficient, and if I ever got water in the motor during a water crossing etc. then I can do it myself, not need to go to a dealer.

 

Ok. Just came across this. Sadly I'm the owner of that oil filter in the picture. Luckily from the advice I've received everything should be ok. Fingers crossed.
Probably not the right spot for this but blocking the erg would also help keep the oil cleaner. Is this true? If so what else would need to be done before doing the block or can you just block it with no ill effects?

Just block it, as said in my OP, it was the EGR block that made me look towards longer schedules 7500 then after tests onto 10,000, before that the oil would be black as and foul smelling by 5000.

Yes, absolutely I've done that many times. Next year I'll be doing a 12000k round trip so at least 1 service while out in the scrub .

 

I dont keep the oil more than 5.000k.
Now i only have 3.000km with the current oil (10W-60), but the winter is coming and -15/-30oC is not unusual so i'll keep it until the end of november and drop it. Dont think i will do more than 1.000km by then .. so it will be 4.000km.

 

May i ask why are you using 10-60w oil for cold winter? is there any reasons such as oil pressure etc? as we are using 5-40w in a much warmer climate here in australia. but i do find that the oil pressure at operating temperature is a bit lower than the delo400 which is 15-40w.

 

In winter i use 5W-40 .... but until November the temperature wont drop to bellow 0 (or at least it shouldn't) ... in November, no matter what, i'll switch to 5W40.

PS. Usually, where i live in Romania, snow tends to appear in the 2nd half of December or January. Usually. After snow, freezing cold is almost a rule. Some snow you can expect in early February. After March , it is safe to return to 10w60....

 

One of the reasons I fitted a bypass oil filter was for convenience. Sure there are some cost savings as well, but 5000km comes around quickly, and when on a long trip you can almost guarantee you will need an oil and filter change mid-trip. Having to do changes so often was my main reason for changing to a bypass system.

Any reason why no-one has mentioned it for the 3L engine? For you blokes going on long trips it would be a benefit I would have thought.

 

What oil bypass are you talking about ?
Romania is a small country compared to Australia, a 5.000km trip would mean to circle around my country, wich i cannot see any reason to do. The closest mountain is 120km away from me, but what happens on that mountain is another story. Long climbs, mud ... different story.
Anyways...what oil bypass mod are you talking about ?

 

In our case, a bypass oil filter is a filter fitted in addition to the factory full flow oil filer. A bypass filter will filter a small volume of oil, but to a very high level. So, you would fit a remotely mounted bypass filter, and run oil lines to a and from the engine to filter the oil. Just like in the photo above.

Some engines will have these filters fitted from the factory, but most passenger vehicles do not have them.

 

zd30 cannot ( very hard) to do oil bypass due to the oil filter design......

 

I believe ive seen it done on a ZD30.

I'm not sure I see the point of it really, I couldn't be bothered and I do a lot of trips.

 

Each to their own I guess. I found that 5000km can come around real quick, and I seemed to be constantly getting close to my next service all the time. Servicing every 10,000km for me makes it much easier, and of course on a long trip it can be avoided while away.

In your case your water injection should have a positive effect on your oil too.

 

I was doing 5k changes but now I'm doing oil and filter @ 10k. Delo 400 and genuine filter every time.

 

I'm up to my 3rd service since blocking the EGR. Normally by 5000km the oil is thin and black. Have done 4000km and the oil on the dipstick is still a nice golden colour. Will drop it at 5000 again to confirm, but may increase the interval if it's good.
