I'm interested how the oil can play a part in fuel economy. I can see how it can affect the protection of the engine. Is it something to do with internal friction?



Ok, this is strictly "Oils101" stuff...I'm not an expert, so please jump in anyone if I say something that is not correct.

Oils are designed to separate metal from metal. Under load, thicker oils do this better than thinner oils, so its preferable to have a thicker oil than a thinner oil - all other things being equal. But the viscous drag of oils (that tends to prevent the "moving" part from moving freely) is higher for a thick oil than a thin oil. This means that assuming the lubrication ability is adequate, an oil that is thinner will be more slippery, and friction (and thus fuel consumption) will be reduced.

Next issue is temperature. Base oils have a tendency to become thinner with rise in temp (think of honey and what happens to it if you warm it). So as an oil gets warmer, its ability to keep the metal surfaces apart drops. Too thin, and the metal parts will still rub together.

Last issue is penetration. A thin oil will spread between the metal parts more easily than a thick oil.

Balancing these last two is where multigrades come in. When an engine is cold you need the oil to be thin so that it penetrates quickly and separates the metal surfaces as the engine starts. Once the engine is hot, you want the oil to be thick. This is achieved by adding substances that work the other way around - they become thicker with rise in temperature. So a 10W-30 oil acts as a 10 (thin oil) when the engine is cold and penetrates quickly between moving metal parts. When the oil warms up it acts like a 30 (thick oil) and provides better metal/metal separation.

There are other issues like "clingability" that refer to the ability of the oil NOT to drain out into the sump when you you stop the engine, but I won't go into them.

So the ideal oil would be a multigrade that had fast penetration, didn't thin with rising temp, and was super slippery so that it caused no drag (thus gave better economy). But such a beast isn't available and it's all a bit of a "swings and roundabouts" balancing issue.

Hope this helps.

Jeff.

Hi again,

I really should quit while I think I understand. There is a great discussion of HTHS in this thread.

But now my head hurts!

Jeff.

Hi Jeff,
Thanks for that. You're right, HTHS does my head in too. Thats good to hear. I wonder if it is possible to ask Nissan tech to provide us with a list of compatible oils we can run in our diesels. That way it will remove some of the ambiguity.

From all accounts, none of the dealers seem to be using the same oil across the board, which I find bizarre. No wonder they have a habit of using wrong oils in the wrong vehicles.

Regards,
Aaron

Re: T31 M9R diesel oil


So for those of us up in the northern warmer parts of the country. A 5W-40 oil is alot better than the 5W-30 oil?
Or just go the 5W-30 castrol since i'm gonna be touring the country?

Just trying to work out what to order on the weekend when I go shopping, for a few litres of oil for the first change and the 5L spare that I want to take with me.
Going to try and get another 2500km on the exy, to get it at least to 5000kms before the first oil change before I go on my road trip.

Re: T31 M9R diesel oil


Ok for the past 14 years I have been using penrite oil and I have prefered it in the cars that I used to run castrol in.

Is the Penrite Enviro+ 0W-40 suitable for the MR9 engine?
http://www.penriteoil.com.au/products/motor-oil/enviro-plus/enviro_plus_0w40

Pick just Nissan and the next drop down with show the right engine with the DPF.
http://www.penriteoil.com.au/oil_selector.php

http://www.penriteoil.com.au/pis_pdfs/2Enviro%20+%20Engine%20Oils.pdf

Oils are not my best thing for choosing, but it looks like to me that the Enviro+ 0W-40 should be compatible. But I would perfer that someone who knows this stuff and can confirm it for me.

EDIT: some more info http://www.penriteoil.com.au/tech_pdfs/142%20ACEA%20C1%20to%20C4%20AND%20ENVIRO%20APPLICATIONS.pdf

Here is some inside information for you guys emoticon

The genuine Nissan diesel oil is in fact Shell. When the diesel first came out here in Australia Shell didn't have the Nissan packaging ready in time, so dealers would use Shell oil packaging. This has now changed and the Shell oil is packaged in a Genuine Nissan packaging and probably sold for much more than Shell would sell it for.

Re: T31 M9R diesel oil


I talked to one of the service guys at Nissan in Mackay,Qld. He says he sees no reason as to why not to run the Penrite oil as long as it matches the specs for the castrol that is being run in the exy atm.
So looks like i'll be putting some enviro penrite in on thursday next week before I go on holidays.

EDIT: oil is envrio 5w-40 and it will be done by my local mechanic. Its good when you know the owner.

Re: T31 M9R diesel oil


Hi Carts,

I, finally managed to source the Castrol Magnatec Professional C3 5W-40 at the local Castrol agent (Reliance). It's only available in a 20 litre container or 200 litre drum - I've been quoted $166 (20L) but they are out of stock Aus wide at the moment - expecting the next batch early September.

Castrol now have another C3 low SAPS oil Edge Sport 0W-40 - and this I've seen in 5L containers at the local Auto store that is Super Cheap. Note that there are OTHER Castrol Edge Sport oils of a suitable SAE grade for the M9R Exy (including a superseded 0W-40) that are NOT C3 compliant - so check the fine print on the side to make sure the one you pick up is definitely C3 rated.

Cheers,

Jeff.

Jeff,
Magnatec pro C3 sounds like the goods then. $166 for 20L isn't too bad considering what shell helix ultra extra sells for in 5L containers.

Cheers
Aaron
