Default Could it be?! MPG

have been using Shell for a year and pretty happy with it. No Chevron around here like I read about on the forum.
So, Sunday I decide to use Hess's high octange, about $3.02 around here. Been driving the Vette since the weather has been great here ( kind of slow city traffic). So I take a small cruise over to the beach to check on some property and hit both city and highway traffic.
So to make a long story short I check my average MPG, (not the inst. mpg) and find that after a qt. of a tank of gas my MPG now sits at 20.5. Can the difference in the type of gas make a big difference? It's gone up 2.5 in a short period of time, and with highway driving I expect it to go even higher.
Just thought I'd share and see if anyone else has had a similar experience.

I buy most of my gas at SamsClub. My city average is around 20.5. The times I've used Shell gas, my mileage has dropped.

Yes, the diffrence between winter blend and summer blend can make a diffrence in MPG, even in the same brand of fuel.

I know I'd have to drive more than a 1/4 of a tank out to feel like I was getting an accurate reading. Unless of course you drive exactly the same way all the time.

Most of my gas is purchased at a "WaWa" mart/station, occasionally Sunoco, all 93 octane. 21-22MPG surburban-city/29 MPG Hwy, rarely varies. Measured by calculation, not dash reading.
