Default Will the quality of gas affect mileage?

I have been getting gas DELTA gas station and noticed that i have been getting bad mileage.
Do you think if i get premium gas at Exxon/Mobil i will get better mileage?

Not everyone has the same gas stations as you, i know where i live in NY we dont have Exxon, Delta, Shell we mainly have Hess, Sunoco, Kwikfill, et. and the quality of fuel does affect mileage.

Considering most fuels are processed in the same manner, there really won't be a huge difference in running different "brand" fuels. Running different octanes will obviously sway your car's efficiency, as it effects how the fuel is burned.

I use the lowest octane level gas which is regular.
Should i use higher for more efficiency/mileage?

Higher octane will not improve gas mileage.

Running an octane other than what's called for, by the manufacturer, can actually cause poor fuel efficiency.

I am guessing its the 'quality' of the gasoline that this gas station sells is very poor as compared to Exxon/Mobil or Shell gas stations.
I am gonna try 'better' gas this time.
May be it will help.??

Doubtful. It's probably down to your driving style, and the nature of the roads you travel.

May be i should try the 'Fuel System/Injection Cleaner' 'Gas treatment' or something in that family?
May be changing the rotors will help? May be the distributor cap?
May be the catalytic converter? May be switching to synthetic oil to reduce friction?
May be changing the Oxygen sensor would help?
May be switching to a high air-flow air filter such as K&N Air Filter?

Something!!!

Maybe you should stop worrying about your car so much. If it were getting less than 20mpg, I'd be worried. If you're getting consistent fuel issues, run some Seafoam through the vacuum line (look it up on youtube).

The biggest factor on fuel consumption is your right foot.
Try easing up on that first.
There's all sorts of crap about "Top Tier" gas vs. the rest, I dont really buy into it. I refuse to buy no name brand gas because both my cars are a little tempermental with it, but for the most part, gas is gas.
Try another station. If you keep filling up at the same place, maybe the tanks are wet. Buy someplace else see what happens.

As I already stated, search on youtube. What car it is, is irrelevant.
