In my case, it only cost 30 cents more for 91. Maybe Ill try premium in my next tank and see how it goes.
is premium fuel worth it?

We get gas at Sams Club because its usually a bit cheaper than costco, but I just checked the prices at both and they're the exact same. If its the same when i needa fill up again, I may go to costco instead considering they have "top tier" gas unlike sams club.
Absolutely, in Alberta land, if Costco 87 is at 1.50 per litre, 91 is only ~.08 more, so well worth it by my experimentation.

Challenge: find one independent website that states higher octane fuel improves mileage. It doesn’t. This, from a Toyota dealer, is typical of the online consensus on this topic:

Will I Get Better Fuel Mileage With Premium Gas?
May 5th, 2017 by Toyota of West County
You pull up to the pump to fill your tank. On the sign, you see premium gas shown as if it’s the best thing since sliced bread. It makes you wonder what it actually does for you. Does it make your car run better? Does it improve your fuel mileage? What is the benefit to using premium gas?
The ‘Premium Gas’ Deception
Instead of referring to it as premium gas, a better term would be hi-octane fuel. The octane rating in premium gas is higher, and all that means is that it is a more stable-burning gasoline. But does that mean it’s better for your car? Only if it’s required.
Does My Toyota Require Premium Gas?
Currently, there aren’t any Toyota models that require hi-octane fuel. The minimum octane rating your vehicle requires is 87 octane, which is standard pump gas or regular fuel. While it’s best to use top-tier fuel from major fuel station chains, you don’t need to use premium gas for your engine to run well.
What If I Use Premium Fuel?
There’s no need to use premium fuel in your Toyota. However, if you choose to do so, there aren’t any negative reactions that will occur. Your engine will operate properly using premium fuel without any concern.
Will I See Improvement in Fuel Mileage?
There’s very little chance that you’ll notice a difference in fuel mileage. If you do notice a difference, it will be negligible at best. Your Toyota is designed to operate at peak efficiency on regular gas, which is 87 octane.

Your trucks, your bucks, but objectively, buying premium is a waste.

Pure-gas.org - ethanol-free gasoline in the U.S. and Canada
I use this page a lot for finding Ethanol free. I think the SE region of the country is a little more forgiving allowing us to use it. These stations aren't plentiful, but they are located close enough to me to make it doable.
I have an 03' V8 that I figure considering it's age, it will help the fuel system to run "E" free. Compression ratio is 9.6:1 in these older 2UZs, so I run the rec 90 octane.
Anything more than 90 is kind of a waste.
Now the 5th gen V6 is 10.4:1, but with the Dual VVT-i being able to adjust timing on the fly when the knock sensors kick a warning, it will run fine on 87 or 93.
You may have a little trouble climbing a steep grade at altitude on 87, but for 80% of the 4Runner owners out there, 87 is fine around town or cruising at hwy speeds.

There is a lot of misinformation in here.
Higher octane than your engine calls for is a waste of money.
Lower octane than your engine calls for will run, however your engine will detect it and retard your engine timing resulting in reduced power and fuel economy.
