91 now $1.42.9c a litre

Just drove down Te Ngae Rd in Rotorua and there are people backed up on the street trying to get into Mobil and Gull. The Gull is a promo price i think and Mobil just down the road have matched it. A good start to the Xmas break if you can get anywhere near it.

So much for peak oil.

88.9c for diesel today in Whitianga, long may it stay as such.

Here is an interesting report from the International Energy Agency. Explains low prices and what is anticipated for the rest of the decade.

.84 cents in Hamilton Gull for Diesel

The promotion lasts until tomorrow.

Thanks for that, very interesting

73c at a Caltex truck stop in Welly. Shame our petrol is not cheaper.

91 octane at Challenge in Rotorua was $1-47 (less 8 cents/litre for Gold Card holders!) yesterday but they said that was the last day of the sale. I think just about every car in town must have had its tank filled. ( 95 octane for the old cars, though, was still $1-79. )

That makes interesting reading. Increasingly volatile oil prices driven by more variables than you can shake a stick at, and I note that the rise of electric vehicles is completely ignored in that report. China's rapid development and uptake of EVs alone will result in a noticeable effect on global oil demand and price.

As our driving is mostly by EV it is comforting to be largely just a spectator of the vagaries of the oil industry, though still exposed to the international political instability that results. And pump prices need to drop a long way further before they are even close to the 1.5c/km our PV generated EV charge gives us.

harm_less, Dec 20, 11:32am
Incidentally using the rated fuel consumption of a Mazda 3 (which is similar in performance to our Nissan Leaf EV), of 5.7L/100km our recharge cost of 1.5c/km is equivalent to a petrol price of 25c/L, or 67c/L at retail electricity cost if we charge from the grid.

Running costs usually is probably less than half the costs of owning a new vehicle. Mine cost me $1000 total in depreciation last year having done another 40'000km. What would your leaf cost?

harm_less, Dec 21, 11:32am
The market price on Leafs has risen due to the drop in the NZ$ against the US$ combined with a big increase in demand so 'depreciation' over our 15,000km has probably been negligible as a result. The trade-in price against a Tesla Model 3 in a few years will be the real test in that regard I guess.

The other major running cost of running an ICE vehicle is mechanical maintenance but as an EV has no transmission or drive train we are onto a winner on that front as well. No attention needed on the suspension, brakes (mostly regenerative), tyres or windscreen wipers to date.

91 still $1.79 as of yesterday but we do get shafted for everything.

Harm less, a genuine question (not a dig), given that the cost of operating your Leaf is currently artificially low, what do you think the appropriate Road User Charges content should be set at (based on distance travelled) once RUC and Government taxes have been established for EV's and PHEV's?

stevo2, Dec 21, 3:56pm
Something I have been wondering as well. Its gotta happen, its just a question of when and how much.

harm_less, Dec 21, 6:53pm
Given that EVs are exempted from paying RUCs until 30 June 2020 a bit of fortune telling is involved but I think it would be safe to claim that NZ's (and most country's) vehicle fleets will have a far higher percentage of EVs then than they have now. Most vehicle manufacturers now have EVs in their range or in some stage of development. Ford alone plan on having 13 EV models in their range by 2020 http://www.theengineer.co.uk/ford-to-invest-additional-4-5bn-into-electric-vehicles/ Another significant influence to EV numbers and the economics of running them compared to fossil fuel powered vehicles will be international oil prices which by 2020 will be on a skyward trajectory with the political and technological induced current glut well relegated to history.
So the question is probably best answered in current day terms. Presently RUCs for light vehicles (less than 3.5T) are 6.2c/km (incl GST) https://www.nzta.govt.nz/vehicles/licensing-rego/road-user-charges/ruc-rates-and-transaction-fees/#RUC-rates-for-distanc
e-licences-powered

Considering that most EVs presently represented in NZ are well under 3.5T, and unlikely to be towing a trailer, a rate of about half (i.e. approx 3c/km) seems reasonable seeing as how RUCs are levied in order to contribute to maintenance of the roading network. The proviso that must apply though is that if EVs pay RUCs then part of the RUC fund is earmarked for roll-out of a comprehensive NZ wide EV charging network.

Incidentally even if taxed RUCs at 6.2c/km (and charged at retail power price) the running combined running cost for a Leaf would be about 10c/km. Based on the Mazda 3's 5.7L/100km fuel consumption with petrol at $2.00/L it costs 11.4c/km to 'run' fuel-wise.

PHEVs are a different case again as they pay part of their RUC equivalency (and ACC) in the petrol they consume as hybrids, and the EV vs ICE operating ratio is going to differ widely between vehicle model and individual owner use for every single vehicle.

One point worth noting is that the "artificially low" cost of running an EV when compared to an ICE vehicle is largely because most of the energy contained in fossil fuels is wasted as heat when it fuels an ICE. An EV however generates negilible heat and even recaptures energy from the vehicles motion by way of regenerative braking.
