In a few days when my car hits 1/4 I'll be hitting up V-Power from shell.You're just wasting money by doing that. The engine is designed to run on regular unleaded. Premium provides no benefits.
It's still good to use Shell and Chevron since they are top tier gas stations.
Premium is for higher compression engines and some turbo charged engines. Unless the engine is designed for it, you may possibly lose some MPG for the computer trying to adjust to the higher octane.

362 miles, 10.279 gallons filled, 35.22 mpg @ 75 MPH on a flat highway in a 2015 Toyota Corolla LE Eco Premium.
414 miles, 10.135 gallons filled, 40.85 mpg @ 70 MPH.
I bet I can do 450 miles @ 65 mph. The sweet spot seems to be around 60-65 mph for most cars. The car is definitely exceeding EPA ratings.

honestly i feel more torque when I'm on a full tank of premium.....i have a shortram intake and when my gas tank is at the half way mark on a tank of premium and i slam on the gas and it is sluggish and doesn't take off immediately, but when I'm on a topped off tank of premium its very quick response that happens and the torque is very significant...
because before I only used regular from chevron....but i was curious and switched to using only premium and i noticed some performance gain (torque) not sure about horsepower....could only be in my head but since than I've always used premium, whether its good for my engine or not good i have no idea, i just drive my corolla really hard...
Butt dyno is not a good measure of this. You would need to see it on a dyno. A lot of aftermarket exhausts and intakes are more "feels like more HP" upgrades rather than real world. The sound is the first thing that makes you think it's more power. I assure you a lot of it is in your head. Now if the intake was well designed and the exhaust was as well with a header, you could tune the engine much better than if it had stock parts.
Putting 93 octane in a car designed for 87 octane is not boosting horsepower. If this were the case, no one would use regular unleaded. The car is tuned to run and not detonate on 87. The higher octane isn't being utilized.

I replied already with my answer above.
If you're driving when the range says 0 miles, I hope you enjoy pushing you car. It's pretty common sense. If you're in an area with several gas stations, I don't see an issue with waiting till the light comes on, but I know many play it safe and fill up at 1/4 tank or higher.

Torque is actually more meaningful than horsepower honestly. There's no evidence that would point to simply changing fuel giving you more torque when the computer is factory tuned and specified for 87 octane. You would need to provide numbers to support your claim. This is a low compression engine at 10:1 and does not benefit whatsoever from 93 octane.
You can Google search this and you'll see this myth get debunked real fast. You could put in race fuel in this car and you're actually hurting it more than helping it. The only thing the premium fuel does is protect against early detonation which is something you do not need to worry about in this car.

It all depends on the factory ECM calibration. Many manufacturers program for regular, but constantly use the knock sensor to adjust to higher octane fuels. Some Fords take advantage of this and can see a small increase. If Toyota uses a calibration that seeks higher octane, then it could see a small increase. I just think premium is a waste. higher octanes are very useful if you drive up steep grades with full loads on a hot day though. Just remember that higher octane fuels do not burn as readily and can hurt performance if the calibration cannot take advantage.
