Just bought 10.6 L of diesel (about a half tank) for the smart in Nanaimo BC for $2.069/L. That's 8 cents CHEAPER than unleaded. That will take me the better part of 300 km.
Hmm AndoHarking back a few days, RON numbers are, as I understand it, simply a scale of resistance to detonation.
If your car does not have a compression ratio which requires high RON fuel, there is zero advantage in using a higher RON fuel, than the manufacturer specified.
I see that it is commonly spoken about on the assumption that if you buy higher RON fuel, you will get better fuel economy.
That, I believe, is not the case. If the label on the filler says "minimum 91 RON" then run it on 91. Or, even better, E10, which is the cheapest. That's all I use.
Hi.Hmm Ando
Well I use E10 94 usually and it is OK. But it is quite possible that using better Ron fuel might give better fuel economy and/or performance. All modern cars have high compression ratios and with a turbo that gives very high pressures. So the engine ECU monitors all the sensors to avoid detonation and uses the knock sensor to monitor staying on the safe side of the settings. But if the ECU decides that a bit more advance and/or boost will be OK then it will crank up for better results.
Marvelous technology we did not even dream about back in the days of hotting up the old cars and using leaded fuel !! Modern cars just work too without tinkering or playing up either.

I'm trying to work out whether I'll get more kms per kg out of red gum or iron bark with my nearly completed steam car.
There is a pent up pressure due to the last two years that put a strain on all retailers, their landlords etc, as most did the right thing absorbed costs, lowered margins and with all that goodwill businesses survived and got through the pandemic lockdowns. what was noticeable is that local and state authorities did not reduce their charges. They did advise that they would accept payment plans, but there was no reduction of rates and taxes.As we can see the relationship between oil price and fuel price is not precise. The discrepancy with 2014 when oil prices were similar to today but prices much lower is also noted in the U.S. where fuel prices are spiking over $6 a gallon in California (with up to $7 in Los Angeles). On the other hand a fall in oil price does not take the fuel price back to the previous level. Compare 2006 with 2021 where the oil price was lower.
Fuel pricing in Australia is opaque. We have no idea of oil company margins but it is noted that their parent companies overseas are posting record profits.
The grasshopper philosophy. What could possibly go wrong?Our Govt has done the Liquid Fuel availability study in 2018.
We are so close to a national disaster

The difference between the price of a barrel of oil, and the retail price of petrol, is not 'the refiner margin'.A view of Australian fuel price compared to crude oil price. Fuel prices in AUD per litre, oil in USD per barrel.
So we can see the refiners margin is nearly double 2014.
