Which gas is better for Nissan Rogue?

[Kash]

Hello,Sorry if this topic has been discussed previously, I do see a couple of threads on gas related discussions but not specific to gas brands.

I have noticed significant differences when I change the gas company and at times gas stations for the same gas companies in the same city and in different states.

Which gas gives best performance vis-a-vis, fuel economy , detergent and engine cleaning quality, ecological foot-print ie more green and less harsh to environment ?ThanksKASH

I think the best gas would be not mixed with ethanol. The octane numbers will not make a big difference in mpg but will provide more heat as more octane you will fill in. Using 87 but clean without ethanol would be the best choice.
