93 octane question

[johnymac]

This could be a stupid question but here goes.

I like to run Sunoco 94 octane in my truck ZZ4 create motor, only calls for 92 or 93 I think.

There are no real close Sunoco stations near the house so I have to take a ride to the nearest staion, not to mention these stations are much more expensive than any others I have filled up at when out of time.

I am thinking of just running a high quality 93 octane.
Close by I have Citgo, Mobil, and Irving close by the house.

I there much difference in the gasolines? I am thinking not, but figured someone out here might be able to set me stright on the best gasoline to buy?

Or is there another station that I haven't listeded that has a better 93 octone.

Thanks guys!
