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.

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

 

[yrrab]

thank you

 

[yrrab]

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

 

[yrrab]

Most inferior oils need a higher viscosity when cold so that they don’t thin too much at operating temps.

Is this measured with the viscosity grade index



Thank you again Steve for your help information

I'v not long own a early 07 nissan serviced it for the first 80000
its looking at the 90000 thinking of doing it myself

Another advantage of having a higher cSt number at 100 deg C you may have a bit more play if the viscosity additives start to brake down

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.

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👍

 

[luckyyrr11]

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,

 

[gavcan01]

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.

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 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!!!

After reading all the posts and trying to take in all the information, trying to wrap my head around it, constantly looking things up, I feel like I will end up needing a giant chalkboard filled up with numbers and stats.
I can imagine my wife finding me in the garage with me in the corner covered in oil muttering about the difference in brands and grades.

You really can't go past Delo MGX 15w40 these days, works well in any ZD30, have been using it for years after trying many, I won't touch synthetics, have seen issues with sludge.

Lol, there are many opinions out there, we can only advise based on our experience, I do a lot of trips so there is a fair bit of experience there.

Mate I've been looking everywhere to find this "Liquid Gold", "Black Tea", "Blood of the Earth". Would you mind pointing me in the direction of where I can buy it?
