got about almost 600 miles total. from a tad over 3/4 to right on top of 1/2 was 87.8 miles. it says 18.8 miles per the gallon right now. not long drives and not at a constant pace so not too bad.

If you try to accelerate any faster without downshifting, yes. But it was maintaining about 1100rpms in 6th gear at the constant speed. Again, as long as I maintained speed the engine was happy, but if I needed to even speed up 5 mph I was downshifting.

My average mpg is around 12-16mpg and i always use shell premium (91 octane)

Why Premium, it is not required for these cars.

A lot of things are not required. Don't have to wax it, don't have to change the oil very 3k miles. People do it because they want too. In theory Higher octane gas can allow the engine to advance the timing more, which when you advance timing you can get more power and better Mileage. If you run a tune and are advancing your timing your going to want to run higher octane fuel to keep it advanced. Anytime a FI engine senses a ping it retards timing, hurting power.

12-16mpg? Jesus... enjoy the accelerator pedal enough?

You're definitely not making a good case for why people should use 91 octane if you get that bad of MPGs with it. I get 23-24mpg on regular.

Lets put this into perspective. If your 19 gallon tank is actually empty. The price different between low grade and premium is .20 . So if your tank is empy your saving a whole 3.80 . Skip one Starbucks and you can put premium in your tank and not even notice it.

Basically, all premium fuel does is resist knock.

A fuel with a higher octane actually burns more SLOWLY than fuel with a lower octane. This is because the fuel is less volatile and requires more heat input before it begins to ignite. high octane fuels will actually make your car HARDER to start on a very cold day. Higher octane provides no additional performance for cars that are designed to run on regular gas.

But in the case of a tune and some performance modifications, it may help.

So since I fill up twice a week, I will save that 400 year for some accessories. Unless I get a tune........
