6x6 using oil

[Summiitt]

My 6x6 working up in the bush is using a bit of oil, it's doing about 1000km/week loaded and driven hard.. 135k on the clock, it seems too early to do a rebuild, thinking of going to a different oil, any suggestions welcome..

[350RRC]

Both the ones I saw at the Wombat weekend would be using a little bit too. No one seemed too stressed.

cheers, DL

[weeds]

How much is a bit??

If the wading plug in or out......?? If it on remove just incase the bell housing is filling.

[Summiitt]

2-3litres/10,000km..

[350RRC]

Sleep well.

Those engines could have spent quite some time idling too. Never a good thing for diesel engines in my book. Still 2 to 3 l/10,000km isn't excessive for the amount of work they're doing. ..

[Summiitt]

Yes I'm. Pretty sure they have done a ridiculous amount of idling, but we have tried to burn the muck out by working it hard.. Hoping the oil consumption settles down..

ITs a wreck, its only going to get worse and cost you a fortune in the long run.

I'll take it off your hands for nothing and wont hold its poor condition against you if you promise to chuck in enough spare oil for me to drive it up into the NT where such major oil consumption isnt a problem yet.

[87County]

You don't say what brand/type of oil that you're using. Sometimes changing to a different brand/grade/quality can reduce consumption.

[camel58]

My 6x6 was using oil out of the tappet cover breather. Pulled the black plastic box out and washed it in petrol put it back . I have done 20k and had no more problems .

That's not really very bad at all.
if it start burning that every 100 or 1000km it might be worth investigating.

see what happens after a few full oil changes and the crud gets washed out.
use a decent quality oil like Castrol RX super or Isuzu Gold 15w40.

The manual says SAE40 so I use Penrite HPR40 25W-70.

[Chris078]

hmm. I thought SAE40 OMD115 was 15w40. Certainly that is what everyone I have spoken to uses in their Perenties

[Davehoos]

Toyota dealer told us that the reason their product used oil was that we used dello 400 LE 15W-40. we advised to use a synthetic 5W-30.


The trial of a few new vehicles vehicles that we picked all used more oil with the 5W-30. and showed no other benifit in the 120K that we keep them.


The Isuzu we have make oil.

[isuzurover]

The manual says SAE40 so I use Penrite HPR40 25W-70.

Firstly that is a petrol oil, so not suitable for diesels.

Secondly it is far too thick.

Just double checked and the manual says SAE grade 40 (OMD 115) but that is 15w40.

Mick if you really are running 25w70 I'm amazed that motor has not had a failure of some kind. That oil is way too thick.
You should change it and enjoy a huge increase in power. Your oil pump will love you as well.

Apart from the viscosity issue, more important is that the oil he quoted is a petrol engine oil, which means it doesn't have the additive package (surfactants etc) to cope with all the soot that diesels put in the fuel. So the engine will be subject to accelerated wear and sludging issues.

The Perentie manual as published by the ADF says to use SAE40 oil.
Penrite HPR40 oil is SAE40.
I spoke to a Penrite rep, showed him the documentation and asked for his recommendation. He pointed to HPR40 oil. The Penrite rep I would suggest has a greater knowledge of oils than most.

Everyone is entitled to their opinion. You are and I am. I'm a fellow who wants opinion to be backed up by documentation. Verifiable documentation, not just someone's opinion written on a piece of paper.
I can produce the ADF advice to use SAE40 oil.
Ok, so you use a thinner oil. Where is the documentation that supports your choice?

I'm pretty sure they've stuffed up Mick. Reading through Penrites page on that product (http://www.penriteoil.com.au/products.php?id_categ=1&id_viscosity=162&id_products=589), it seems it's a petrol oil, not a diesel oil. Then there is the viscosity issue, which naturally now I'm looking for it, I cannot find the proper government page that describes the definition of OMD-115 but I can say I went through it and 15w40 was what it came out as.

How long have you been using that oil for?

[isuzurover]

HPR 40 CODE: HPR4001, HPR40005, HPR40020, HPR40060, HPR40205
Penrite HPR 40 is a premium 25W -70 non-friction
modified, high viscosity engine oil. ...
...
Penrite HPR 40 meets the requirements of API SL/CF.
...
Designed for use in older design, ... petrol engines
...
...
Also suitable for older naturally aspirated (non-turbo) passenger car diesel engines. Newer light commercial and four wheel drive diesel vehicles should use Penrite HPR Diesel or HPR Diesel 15 as appropriate.


The above is data from penrite's pdf.

You can see it is not a diesel oil - penrite say you "can" use it in old, light duty, non 4x4, diesels. It is only rated to API CF. Proper diesel oils like Castrol RX Super and Penrite HPR Diesel oil are rated to API CI-4 Plus which is several generations better in additives.

But by all means don't believe us and continue to destroy your engine...

And from someone who maintained the things for countless years...

omd 115 = 15/40 diesel engine oil.

nearest current civvie oil is caltes delo 15/40 but caltex rx super is also on the cards.


at the end of the day, almost any mineral 15/40w diesel engine oil is good for the omd115 spec.

[Svengali0]

For what it is worth, the 6x6 engine & trans fitted to my 130 towed 2.5 tonne to QLD (3k+ KM) and back last weekend without a skerrick of oil use. I use shell Rimula 15/40- as with all my diesels.
Just adding my two bob's worth.

[Blknight.aus]

HPR40 not suitable for the suzi unless your suzi is approaching what I might call "worn out"

http://www.penriteoil.com.au/Portal/product_images/web/HPR40005.png

25/70 is something I'd sling in a high speed light load diff.

from 10 seconds on their site I'd probably grab

http://www.penriteoil.com.au/Portal/product_images/web/PMO15005.png

that or

http://www.penriteoil.com.au/Portal/product_images/web/MONO40020.png

that
as a suitable replacement for omd115.

but Im a bigger fan of nulon and castrol oils.

[Trigger82]

I agree about the penrite rep been wrong.

Even going to penrites website and using the product finder its listing HPR Diesel for the engine which is still a 20w-60 but at least is designed for diesels.

So, does penrite have it wrong or does the rep?. Dont forget the reps only human and was probably just having an off day.

[rathgar]

Penrite HPR40 is not SAE40. On the label it says it may be used where SAE40 is specified. HPR40 is a multigrade oil. SAE40 would be a mono grade oil i.e Monotruck 40 which is the only one of the 3 oils that Blknight mentions only that states it is SAE40 on the label.
It wouldn't be the first time the ADF (User) documentation was incorrect or inconsistent. If you want documentation Mick have a look at what the manufacturer (Land Rover or Isuzu) says.

[Chris078]

<edit> Finally got a reply from Penrite to an email I sent them which just seems to add more confusion.
What was the recommended oil for the 4BD1 Counties? At least that would come officially from Land Rover in
civilian spec oil.

Interestingly, the Penrite site has a 'finder' that recommends an oil based on your car.
it has the 4bd1 4x4 Landrover listed as the 20w-60 (HPR Diesel)
but if you select the 6x6 it recommends 15w50 (HPR Diesel 15) as the preferred oil with 15w40 (Diesel FX)as an option.

Comments: Hi. I recently purchased an ex army landrover 4x4 which specifies OMD-115 grade oil. I have been told you were the supplier of that oil to the ADF. Could you tell me what the civilian equivalent of that oil would be? I see on your website that you recommend HPR 20w60 for that motor which is a different grade of oil to what I have been told to use.
It\'s the isuzu 4bd1 engine.
Thanks

Hi Chris.

An OMD 115 oil is basically an SAE 30 oil. We have MONO Truck 30, MONO TRUCK 30 SAE 30 (Mineral) (http://www.penriteoil.com.au/products.php?id_categ=2&=&id_products=633).

We don't supply to the ADF but the Mono Truck 30 will meet the requirements. HPR Diesel 20W-60 is listed because we say it can be used where an SAE 30 oil was originally required, with the expected age and wear associated with an older model but go with the 30 and see how it goes.

PLEASE CONSIDER THE ENVIRONMENT BEFORE PRINTING THIS EMAIL

[rathgar]

See attachment from the manufacturer (from 110 owners manual - Australian) The grade of the oil is dependent on the engine fitted V8 vs 4 BD1 The viscosity is dependent on the ambient operating temperature.
Note that a mono grade oil is never recommended and that a 20w-60 is also never recommended.

Has anyone found a documented technical specification for OMD-115? I can't.


The Perentie manual as published by the ADF says to use SAE40 oil.
Mick - Which document? Can you post a link? Don't worry found it!

[isuzurover]

FFS some people are a sandwich short.

There are people on here who have been using Castrol RX super in 4BD1s for 1Mil+ km with no issues... Not to mention truckies that have several million km clocked up on 4BD1 engines...

Yet you choose to find a match to some obscure OZ Army classification, despite the fact that it was probably chosen based on the convenience of the quartermaster's division rather than mechanical sense, and despite the fact that the average army landrover has about 100k km on the clock.

[MR LR]

My brain hurts.

I filled our race car with HPR40 the other day to try and get two more endurance rounds out of a lightly knocking engine. The stuff reminded me of clag glue it was that bloody thick.

I was wondering when you would see this thread Rick. Good to have you back.

[Summiitt]

Yep, I'm going to keep it simple and use Delo 400, I don't think this 6x6 has done much constant hard work, so I'll just keep an eye on oil consumption and see where it settles down to.

Mate if it is pulling OK and not blowing blue smoke I wouldn't worry about it 2-3 litre over 10000k is nothing for a truck engine. Do a compression test if you are worried - should be around 440psi per pot.
