Odd question. Bear with me.

 

 

 

The fuel requirement for a new Subaru Forester in the manual says

 

 

 

For Australia: 91 Octane or higher

 

 

 

Except for Australia: 95 Octane or higher is recommended

 

 

 

So...is NZ included in 'Australia' since we tend to share vehicle specs and if it isn't then how is their 91 different?

Apparently Australia's fuel quality is one of the lowest in the OECD, so this may be why. Quite an interesting read actually as it seems Australia, and by extension probably us too, are not getting the most fuel efficient cars due to low fuel quality.

I thought we also sold 91 here? Do we not?

The NZ brochure lists minimum octane requirement as 91 RON but qualifies the engine performance specs as being obtained on 95 RON as required by Australian Design Rule.

Generally I would say no. Quite often we get different spec cars from Austrailia.

As Examples:

 

  • Previous Generation Outlander is sold with coilover rear suspension in NZ & japan, but separate shocks in USA & Aust.
  • Subaru uses a different badge for the Legacy in Aussie
  • Aussie spec cars often offer a lower base specification than are offered here (hand crank windows etc).

I think a lot of this stems from the presence of used imports from NZ. It is desirable for our spec to match japan where possible. Also little need for Bargen basement new cars here when we can get good used cars from Japan to meet that need.

That said, Subaru NZ clearly are advertising the Forester as having 91 (I assume RON) as the minimum fuel requirement:

https://www.subaru.co.nz/showroom/forester/compare#state=compare&variants=133,137,139

 

 

 

To further complicate the matter, some vehicles have different Minimum fuel grades, to the Recommended fuel grade. My BMW was 91 Min, 95 recommended.

Do you think that means that Subaru is required to have 95RON as the recommended fuel everywhere other than Australia as that is what the engine performance specs are quoted running on, But the ADR allows the car to be tested on 95 despite the minimum being 91, leading to the difference in that market?

If that is the case it is a bit deceptive of Subaru NZ to advertise power figures that are unobtainable on the minimum fuel rating in the same spec sheet (linked above). If this is the case, it sounds like if OP wants the advertised performance they need to run 95...

Nz limit of sulphur is 10ppm from 1 July 2018, so, better than Australia. Doesn't mean that our market is big enough without Australia to get the more efficient cars though.

So, based on all your helpful replies, it’s not terribly clear. It seems that (a) you can safely run the car on 91 but (b) it will run better on 95.

Does that sound about right?

It’s an improvement on the Range Rover it replaced, which was 98 if possible!
