Well researched and written Steve. It will be interesting to see how many oils fall into the category as suitable for the ZD30. I also believe that some of the mods that many of us do, may require the use of different oils to those recommended by the oil companies.

 

Good point Chaz,

Blocking the EGR cuts down on the carbon that makes its way into the oil. CI-4 oils were developed to handle the added carbon and deposits of EGR systems. The carbon deposits are held in suspension by the oil and circulate through the oil system. I have been told that this carbon acts like a mild abrasive ( in a good way ) that helps to keep clean the bores and other internal engine components.

If blocking the EGR system I would definitely extend the drain interval beyond the commonly accepted 5000 km oil change. Just because the oil looks black and dirty does not necessarily mean that it has had it.

Thanks for your feed back Chaz and I welcome anything you have to add to increase our understanding of crank case oils.

Regards,

Steve.

Great thread. A lot to digest. Thank you all for the info. I just bought a 2010 zd30crdi, 200k klm, fully kitted with NADS. Is this list still a good guide in 2021?

 

I had a table to upload but due to the size I was unable to post it. If anyone can help me out uploading the table please PM me.

I added the Delo 400 Multigrade to the list as a reference. It is not listed as a recommended oil for the ZD30 CRD in any of the oil company's lub guides but as has previously been mentioned is a great CI-4 oil.

If you have any updates or additions please add to the list.

If you have used any of these oils it would be great to hear of your experience and recommendations.

Steve.

 

Good info Steve. I have been using Mobil1 5W50 for quite a few years in my ZD30 Patrol at 10K intervals and couldn’t say a negative thing about it.

Personally, I’d prefer a blend with a 40c cSt closer to 100 and 100c cSt closer to 20, so I’ll be switching to Penrite SIN 0W50 at the next change with a cSt at 40c of 108 and 100c at 18.7.

 

ZD30 oil

Good info Steve. I have been using Mobil1 5W50 for quite a few years in my ZD30 Patrol at 10K intervals and couldn’t say a negative thing about it.

Hello Chaz. I'm Jay from the Philippines. I just ask wanna you if the Mobil1 5W50 you are using is a synthetic blend. Tnx.

 

Hi there
I have a 2007 3lt model I'm bout to do my first service since buying and would like to know what you would recommend me to use
Cheers

 

Hi New4x4owner,

You have a large choice of suitable oils depending on how deep your pockets are and if you have modified the engines emission system or not. Mobil1 in 5W50 and Castrol Edge are good choices or Penrite HPR Diesel5 and Castrol Magnatec as a minimum.

 

I have"nt any mods and I think nothing has been done previous are those still good to use? I'm not worried about price
Cheers for your help

 

Hi Chaz,

Right now I have not block the EGR. But as I read the forum I'm planning to get this done so that I can use a synthetic blend. Anyway a big tnxs for the info. I keep you post.

Regards,
Jay

 

JASO Engine Oil Standards 01 July 2012 has been issued.

See "JASO list of DH-1 Oils" link in post #1 for latest revision.

Regards,

Steve

 

Just for a bit of light reading see link to the revised JASO Automotive Diesel Engine Oil Standard.

http://www.jalos.or.jp/onfile/pdf/DH_E1205.pdf

The Nissan Patrol ZD30 owners manual lists the JASO DH-1 oil specification as suitable for our engines. DH-1 classification is designed for "D" diesel engines with long term exhaust emission regulations.

There are two additional JASO diesel oil classifications, DH-2 ("D" diesel "H" heavy duty truck bus) and DL-1("D" diesel "L" light duty passenger car) which are recommended for engines with Diesel Particulate Filters DPF.

The major difference between the DH-1 and DH-2 / DL-1 classifications that I can see is with reference to the limit placed on the phosphorous content. The DH-2 and DL-1 have a max phosphorous limit but the DH-1 does not.

I think that phosphorous is an anti wear additive but has a detrimental effect on the catalytic converter. Hence the recommendation for a DH-1 oil for the ZD30 in the Patrol.

It is hard to find an oil sold in Australia with a DH-1 certificaiton but we can use the specifications in the document to help choose oils that would meet the DH-1 classification.

 

A good read comparing CJ-4 v CI-4 oils. Also talks about the effects EGR has on engine oils.

Motor Oil for Diesel Engines

 

What oil should I use in my ... is one of the most frequently asked questions on this forum and the simplest answer is as per the major oil companies on line lube guides. This is based on the requirement of the engine manufacture. For the GU ZD engine that is: API CE, CF, CF-4 or JASO DH-1. For viscosity number refer to the SAE chart.

The primary purpose of engine oil is to remove heat. It does this by flowing through the engine picking up heat and transferring this heat to the sump / oil pan for dissipation.
If the oil is too thick it will not flow at the optimal rate and therefore spend too long in the hot section causing a hotter operating engine and heat stress on the oil.

Once the oil reaches a temp of around 130 deg C it starts to break down or denature.

The second priority of engine oil is to lubricate. It does this by providing a thin film of oil on moving parts to form a barrier or slip surface to lessen the effects of friction. Additives such as phosphorus and zinc etc are added to improve and aid this lubricating barrier.

Now, to comply with environmental targets, engine manufactures fit EGR, Catalytic converters and DPF’s. (Note the ZD engines fitted to our Patrols don’t have DPF’s). To prevent the rapid deterioration of the Cat and DPF’s and to reduce emissions the oil companies have to remove or reduce the amount of additives.

The link at post #17 above talks about the reduction of additives in the latest and greatest oils as the oil companies modify their oils to comply with the latest emission standards. If you use a higher spec “latest and greatest oil” in your engine you may be paying a premium to kill your engine with kindness.

Engine manufactures have taken all of the above into consideration and specify the SAE viscosity rating and oil grade accordingly.

The Nissan workshop manual “Supplement for Australia” dated Sep 2007 in the MA Recommended Fluids and Lubricants lists API CE, CF or CF-4 and JASO DH-1* for the ZD engine. *For further details, see SAE Viscosity Number.

So the two things you may consider when choosing engine oil are:

1. SAE viscosity rating for the climate you are operating in and ;

2. The oil class or grade.

I am now using Delo 400 “Multigrade” 15W-40 and carry out oil and filter changes at the maintenance interval for severe driving conditions of 7500 kms.

As always if you see an error in my post or have additional info feel free to add.

Steve.

 

Hi
I have interests in a oil with a ACEA of A3/b4 it does not have A3/B3 on the tech sheet

I having trouble understanding the differences between the ACEA a3/b3 and A3/B4
My understanding there not alot? When it comes to were and tere.


Can some tell me if this is true.

 

Hi yrrab,

ACEA "Ax" category oils are for gasoline engines, "Bx" oils are for diesel engines, some oils cover both Ax/Bx. See the link under ACEA in post #1 for more info.

Steve

 

this may sound silly but so i know i'm understanding it wright

the high the um number (2.7 wear section) means more were on the areas?

the 2.8 ring sticking ASF numbers lower are better or worse?

sorry I haven't look this closely at oil before

 

thank you

 

Thank you for the informative post

I have been finding it hard to get my head around why its better to have a higher number at cSt @100 deg C, when the preferable number is in the early teens.
But I think I have it now.
Please feel free to tell me if i am wrong.
I was under the impression that the higher the cSt meant more restriction in the oil.
I assume the engine has a tolerance for the cSt at 100 deg c
I think the lower preferred (manufacture) cSt@100 number it at the bottom end of the tolerance. As the lower number may produce better fuel consumption and lower emission?, But the higher the number may be better on lubrication but not as good on emission and fuel consumption.?

 

Hi yrrab,

Yes the higher the um (micro meter) number the greater the wear.

The ASF unit is beyond my level of knowledge so I will leave that to the more learned on this forum.

cST Centistikes is a measure of oil viscosity. Engine oil data sheets give us cSt @ 40 deg C and 100 deg C as this provides the rough temp range of the engine oil.

For more info see

Viscosity

In your last post you are correct in your understanding of the effects in changes to the cSt @ 100deg C has on fuel consumption but engine wear and oil degradation would be a factor.

What engine do you have in your Patrol?

Steve

 

Old thread I know, but thought of putting it here than in a new thread.

I also noticed in my Owner's Manual the oil spec says it needs to be API OR JASO DH-1

And the following link is the only one I found specify oil grade/type based on the series number and it suggests 15W-40 for my 2012 CRD.

Peak Lube Guide | PEAK OIL

 

OK, a bit further reading if you have the time:

http://www.widman.biz/uploads/Corvair_oil.pdf

And after reading through several information online I come to the following conclusion:

Always select the grade as per the manufacturer


BUT... giving the following important consideration:

comparison of cST from SAE for the given grade


Just a bit of explanation on this regard;

1. The design and manufacturing of the motor never going to be understand by a consumer. So here I am happy to assume Nissan is correct in specifying the correct grade for the motor.

2. This does not mean to buy OEM oils. All it is required to do is to compare the oil market to suit what Nissan specified.

From these this is what I have decided:

1. for 5W-30 (Nissan spec) the oil need to fulfill the following (happen to find one on the internet)

http://www.oilandenergy.com.au/wp-content/uploads/2016/06/SAE-Chart-768x576.png

From this table I need to make sure the oil I am selecting for the motor is meeting the criteria.

So far I have used Penrite 5W-40 HPR5 Diesel but from the spec id does not meet this criteria from the Manufacturer.

So now I am changing my oil to meet these specific criteria and may be going to go with full synthetic as well.

Disclaimer:
This is only my decision and may not reflect a true or correct reflection of engineering background and I do not take any responsibility for the any damage caused because of your decision based on the above information.

 

Hi, can anyone advise if the following oil is suitable for my 2013 CRD engine? Mate can get it cheap thru his work👍

 

hi all , ok so here we go again about oil and what to use lol ,something to ask , has anyone tried the Delo 400 LE SAE 15W-40 oil , is it ok to use in 2009 CRD .or is it better to stick to the Delo 400 SD SAE 15W-30 , they say it is ok for CRD and EGR any help would be great thanks,

 

Digging this one up once again. I know there are many different oils which will work some better than others. Just want to share my experience.
Just purchased my 2011 CRD and about to flush and use Nulon 5W30 long life Diesel (SYND5W30), I used this in my 2000 Landrover D2 Td5 and instantly received and extra 50-90 km out of a full tank of fuel (95l) over whatever oil was in the engine at the time. Only used that oil from then on in and held up great over the time I had the vehicle which included a trip around Australia and living in Mt Isa for a year. Engine was smooth and oil had consistent performance from start to finish of its 7500km cycle, probably would have been fine to extend the change out to 10k.
The rating that matches the ZD30 is API CF. You can search by oil spec on the Nulon website which is handy. I have also confirmed with Nulon it will be fine to put in the Patrol.
Ill post my findings in here when its done maybe it will help someone else.

Cheers

 

This is the oil they use at my local dealer for my 2011 CRD. Sells at $60 for 5L. May help someone choosing an alternative.

 

I have run penrite 15w50 on my crd for last few years without any issues at all. Car has 250odd on clock and has catch can egr block etc and running 21psi and tuned. I used to do 5k changes but lately been going closer to 10 and oil still comes out nice and clean!!!
