Cancelled my order, turns out it doesn't meet the spec required for a DPF which is pretty much all modern diesels ever. And I'm pretty sure older diesels don't use 5W30 so eh, it's not really for diesels in NZ.
If you have a diesel with a DPF (around 2000ish and later, doesn't belch black smoke or require the blue fluid) you need ACEA C3 spec, this is B3 spec.
Repco has this on special in that circumstance:
https://www.repco.co.nz/en/brands/shell-lubricants/shell-hel…The Repco ad doesn't say ACEA C3 but every other source, as well as the picture itself and the model number, does. I'm going to swing by tomorrow to get some.
I've bought these deals regularly until someone pointed these out to me

I don't think that is anywhere near as good of an oil as this Castrol is.
Based on what? The oil probably all meets the same standards, doubt there will be any difference in quality.
My last oil purchase was Penrite 20L, have run it in all my cars for years now and haven't had a single problem. Fancy packaging doesn't equal better product.
It's a very thin oil with worse typical characteristics, a low TBN, and needs a shorter OCI. The Castrol on the other hand has proven itself time and again (including many UOA's) to be one of the best oils available on the AU/NZ market. There is a reason it's BMW LL-01 etc approved.
@limepanda: How can one 5W-30 oil be thinner than the other? The 5W - 30 is literally to do with the viscosity.
@2cheap: It will be "better" oil but if it meets the spec required by your vehicle it won't make any measurable difference.
Better as in it will meet specs that have stricter tolerances, resulting in that it has been tested and proven to have more fine consistency but it will be equivalent to the difference between cooking with a teaspoon measure of oil and a regular teaspoon from your drawer. In 99.99% of recipes it won't make an iota of difference to the outcome.
Buy to your cars spec, getting something better because it's better could be expanded ad infinitum with diminishing returns.
@2cheap: Oil weight is a value range. The only thing that weight means is that whatever viscosity the oil is at a certain temperature fits between the agreed upon viscosity ranges for a given weight. For example a 30 weight oil must have a viscosity between 9.3 and 12.5 mm2/s at 100 degrees celsius. The Nulon mentioned above has a viscosity at 100c of 10.66 vs the Castrol's 11.9. That's a big difference.
@limepanda: Define big difference.
If it makes your car last 4 days longer over it's 30 year lifespan that's not a big difference.
@danvelopment: Combined with the low TBN (8.3 vs 10.2), and the difference in additive package (among other things) I would expect much more wear to occur with the Nulon over a long period of time. You can't really give a definitive answer to your question though due to other variables like OCI, filter, driving habits etc. You might get away with running a poor oil, you might not. Why chance it?
@limepanda: Lol, it's gone from it being better to the other stuff now being poor.
And get away with it?
Your answer makes it sound like 30 years + 4 days vs 30 years.
"The numbers are better but I can't actually quantify the outcome…but the numbers are better. So I would EXPECT it to be worse. Of course I don't have anything that says it is worse but obviously the other stuff is liquid Satan because its number (albeit within acceptable range) is lower."
So why aren't you buying the stuff that gets 12.5mm2/s at 100'C?
@danvelopment: I have not changed my position, the Nulon is inferior to the Castrol. Viscocity is only one part of it as I have mentioned twice now. The Nulon isn't the worst oil out there by a long shot, but it is a class below the Castrol and a couple of classes below the very best oils. The Castrol WILL provide more wear protection, that is scientific fact. You can't just pull out a random 30 year figure which means nothing and say that it nullifies decades of research. The original commentor said he switched from the Castrol to the Nulon due to price, I pointed out that the Castrol is a better oil, you get what you pay for. If you had a low performance motor and used the Nulon and changed it regularly and drove like a grandma it'd be fine, if you drive aggressively or want longer OCI's or have a high performance motor then the Castrol (or any top tier oil) WILL make your engine last longer. (To use your ridiculous example it would last anywhere from 5-15 years longer given what we know about wear rates). The difference is becoming more pronounced every year due to more being asked of modern engines whether it's turbo's, tunes etc.
Great price for a great oil. Grabbed two.
Grabbed 5. Thanks also got the ceramic was from. Meguiars.
Do they expire ?
They'll keep for years if they stay sealed.
they are back!
Cheers, have updated.
Thanks, great buy!
Doing two oil changes for a pair of diesel cars and they each eat 5.3 and 5.9L so got three shipped. Was looking at the 10L Nulon for $100 but then I'd have to get another 2L somehow and the same stuff only comes in 10L or 20L quantities.
They specifically state its good for passenger diesels (although I don't know how much stock to put in "petrol" or "diesel" oil, I'd be surprised if there was any difference).
