which gas brand is better?

[walt101786]

hey guys, i know this may sound a bit strange and all, but i got a question to ask and would gladly to accept an honest opinion...i am trying to do some research to see which gas would give me better mileage and a better over-all performance...first i'm gonna make a list..like i said this is only for research

Shell-rides fast, when i pump ten bucks...it'll last me at least 120-125miles for 3.something gallon until it starts to blink...i get like around 40 miles per gallon

Chevron-rides pretty smooth...not sure how far i'll go with 10 bucks....

76-rides smooth and fast...10 bucks can give me around 125-130...it gives me around 39-45 miles per gallon

Arco-10 bucks....it doesnt even last me very long....as a record....its like around 25-28 miles per gallon

all these gas are the gas i am do research on...but like i said...im just researching and ask you guys to see which you guys prefer...as for me...i'll go either with 76 or shell...last resort would be chevron...and in my area, chevron, shell and 76 are similar in price range...they're mostly around 2-5 cents off...wchih in another words...i put 89 for myself which cost me around 3.11-3.19 per gallon...so u guys could do the math itself and hopefully i can hear for u guys soon
