Only two brands of 93oct here in
PR, and i believe neither exist in the US, and thats PUMA and Ecomaxx. Puma sounds like a good brand name, but it actually sucks, although its supposedly Top Tier Fuel, a lot of people have complained about it. The other brand is Ecomaxx, which sounds cheap as h3ll, but is actually pretty good and is the one i use on my Z.
No complains whatsoever, and actually eliminated the low rpm range hesitation i felt on the Z when i used 91oct shell
Other known brand names like Total and Gulf are also all 91oct
At least we have some 93oct options
