| 1400670 | 2015-05-22 04:55:00 | 91, 95 seemms vintage now. As a cars made in 91, 95. But no other octane blends in NZ pumps to experiment with. Would 95 petrol be a great loss if withdrawn? The namings of 91 and 95 are not related to the years... There are other variants in NZ - many Mobil and BP stations offer 98 (or 97.5), and Gull offers a 98-octane E10, and in some locations even E85. Withdraw 95, and what, ensure all stations offer a 98 (neither Caltex nor Z currently have a consumer-grade fuel higher than 95RON on offer at all)? |

| 1400671 | 2015-05-22 06:36:00 | Just did a fuel search on Google, which turned up a surprising result! "New Zealand: 91 RON "Regular" and 95 RON "Premium" are both widely available. 98 RON is available instead of 95 RON at some (BP, Mobil, Gull) service stations in larger urban areas." I live in a 'larger urban area', so although I use Gull 91/regular around town, it is possible that on long trips I have been running on 98 not 95, which might explain the high km/litre I have been enjoying.

| 1400672 | 2015-05-23 09:02:00 | Had not realised the many variants of fuel locally. Maybe it's all about choice, perhaps to target the discerning fuel consumption concious motorist. Fuel a seemingly basic commodity, perhaps needs a range of blends to satisfy from budget to potential premium users. Not unlike the choices for budget bread and butter - margirine spreads. Mix of cost to benefit - optimal - economy type interaction. But interestingly, recent research by MIT (CBS news article (www.cbsnews.com)) in USA mentions nothing about fuel economy but rather significant overall reduction in emmissions , i.e. CO2 - greenhouse effect, and less fuel consumption. But of course a massive national fleet. Holiday travel distances (even intrastate then interstate) are vastly higher in the US too. So maybe different beneficial agenda in the US. Noted also, if car manufacturer's could build more (and maybe promote) higher octane engines, this could also create savings. The higher octanes could shift to become the regular fuel. |
