which gas do you guys use for 128

[e82vette]

128i 6MT
Chevron 89 mostly
Esso 89 sometimes
Husky 91 sometimes


do you all use 91 or 93??????
if it makes difference, I will switch
cause, I dont know about you guys,, but I think higher octane gas give better mpg from previous experience... but just feeling you know

I switched from Sunoco Ulta 94 to Shell V-Power 91 last summer as I think I'm getting the same performance with better mileage out of the V-Power.

Use whatever your ECU is tuned for.

v power shell only from now on, top tier gas, not sure if the new nitrogen formulation will do anything much, but I am getting better milage compared to petro or sunoco so far since switching.
