Premium in a Toyota? That like putting a 1500W PSU in a tower with an i5, a single drive, and a gtx-980 as the only PCI card.

I just think they're neat!

Most turbocharged engines need at least mid-grade due to the higher overall compression. Plenty of Toyotas with a turbo.
The cap looks to be around 2006-2010 though; before the large advent of them outside of the performance market. (at least in the US)
That's a Lexus rx350 which did require premium before 2012
That explains it. I wasn't thinking of Lexuses, but I guess it's a 2010-2011 if it does need premium.
I guess TPM is living it up all bougie-style in a Lexus.
I am not a car person.
It is unconcievable to me that you can identify the brand of a car from such a partial picture.
I'm not super familiar with cars either, but for people that are, things like the fuel door and cap are unique between different makes and models. If you stare at cars enough, you just kinda begin to know these things
Pretty much.
I recognize the cap and its tether, but not sure what model. (looks close to a 2010 Prius or Yaris)
I'm the same, but then I realized I can likely identify a bunch of makes models and years of guitars and basses by a partial photo.
'Premium' gasoline is such a misleading name.
It is more like messing around with undervolting when you don't know what you are doing.
Maybe.
I was more referring to the efficiency side. In that a PSU is most efficient when between a certain wattage of power draw. Similarly, using a fuel formulated for high compression will be less efficient than one for low compression in an engine that is low compression.
Depends on the compression of the engine. I've got a 40 year old 125cc scooter that should arguably take premium, because it was rated 10:1 when it was new.
My car has the same compression ratio and asks for 87 AKI, which I believe is 91 RON. I have to give it 95 though because that's the lowest they sell here.
Funnily enough, car's only 10 years old. I'm surprised they didn't mandate something higher than... 87.
Never heard of the supra?
Ha Haahwr
Higher octane fuels have a higher resistance to burning, lower octane fuels burn easier. All octane fuels are required to have detergents by law. Use what is recommended by your vehicle and stop wasting money. You will not get more power by using a higher octane fuel, unless your vehicle is tuned to use it or developed to use different octanes like Mazda's sky active turbos.
It's also not necessary to use high octane fuel if the manufacturer recommends it. Modern cars have sensors and computers that adjust how it runs if you fill it with cheap gas so it doesn't knock or anything.
Running on a bad tune is not the same as running economically, octane sensors just determine the amount of tune modification needed to stay as economical as possible.
If you run a tank of the correct fuel and watch your st/lt trims then do the same with improper gas you'll notice they're not at all the same numbers.
