In Australia we have 91, 95, 98. Likely due to the higher temps and increased risk of detonation but I'm no expert. I just put 98 in mine all the time. Not too bothered about fuel prices as I don't pay for it (work).

Our fuel prices at the moment are about $1.76 AUD/L which equates to about $6 USD/Gallon and the car cost $85k AUD (About $76,000 USD at the moment. So yeah, we pay more for everything.

It's the same fuel. Your (AUS) 98 is roughly equivalent to our (USA) 91-93. We just use different rating systems.

AUS uses the RON octane ratiing system while the USA uses the AKI octane rating system.

From wikipedia:
Difference between RON and AKI
Because of the 8 to 10 point difference, the octane rating shown in Canada and the United States is 4 to 5 points lower than the rating shown elsewhere in the world for the same fuel. This difference is known as the fuel's sensitivity, and is not typically published for those countries that use the Anti-Knock Index labeling system.

Costco is top tier.

Q: Is Costco TOP TIER™ certified?
A: Yes. Both grades of gasoline sold at Costco meet and exceed TOP TIER™ requirements

Average is a bit of a misleading figure so let's use median income for full time workers. Median full time income in Australia in 2013 is reported to be about $58k AUD so about $52k USD. Earnings can be very regional as well in a resource economy though. If you work in the resource industry in Perth for example in an management position, you could easily earn 4 times the median. Mind you your house will cost $1M and a pint of beer in the pub is $11.

Affordability index is probably the best way to look at earnings vs cost of living. This is essential to do if you're considering a move overseas for work and aren't on a lush expat package.

It's not gonna make a big difference. Since the minimum ON is 91, anything above that will be a waste. The engine only burns what it needs. The engine will run most optimal at that level. You're not making it more optimal by giving higher octane number than required. Therefore premium gas within the US has 91-93 ON range.

The minimum grade here in the UK is 95 RON but 99 RON will be my fuel of choice when I get round to filling up. My Toyota GT86 used to love Shell V Power Nitro+ which is 99 RON. I consider this the best fuel in the UK.

Been using Costco exclusively, they dug up the entire station and installed some new tanks that add some kinda techron like crap that's 5 times better than EPA standard whatever blah blah but their gas is clean they change the filters all the time that's really the reason I get it there.
