is it true that some gas providers like sams grade of gas isnt as good as say conoco? the reason im asking this is because im kinda low and every single wednesdays at this conoco, the price of premium gas is that same as regular. im wondering if i shuold just wait for the conoco gas or just get sams gas cuz it may be a tad cheaper. this may be a very ignorant question but i was just curious about the quality of the gas.

 

COMPARE TO ALL THE GASSTATIONS THAT I WENT TO I HAD THE BEST MILAGE AND GAS FROM MOBIL.

 

well we dont have any of those stations in LR

 

Shell.

 

different companies are definitely at different levels of quality. i get the best gas mileage with shell. next best is 76, and from that i'm really not sure...i DO know that if i ever have to get the **** gas (some no-name station), it ends up costing me more than the expensive stuff because my gas mileage deteriorates to nothing.
