I used 93 at Sunoco for the longest time and just recently started with V-Power at Shell. V-Power is also rated 93.

I'm sticking with Shell..it might be just me but it feels like I get better performance.

Now I want to try gas with no ethanol..not sure if such a place exists in Delaware or South Jersey. I assume a stock Z can use it without any changes.

Husky nearby me has 87 and then 94 : /
So I looked in the manual and it says the recommended is 91, putting 94 isn't gonna benefit me in anyway. So, I usually fill up 1/2 tank 94, then come back in a couple of days and fill up 1/4 tank 87. Manual says it's ok...

I wish there was pure fuel around here, but I don't think there is... I'd for sure try it. Can you notice the difference in just normal day to day driving? Does it burn faster or is there no change in that?

Don't have a Z just yet but I currently pump non ethanol gas and you do get more miles.

I hear after extended use (every tank) it will get the gaskets in your carburator in a couple years. this was a subject in the hotrodders forum. How to figure octane is the average the octane between the two fuels being mixed. 7:1 ratio of 91 octane to toluene would be 91x6 + 114/ 7= 94.2
Gas stations only have 2 tanks low and high. the octane ratings in the middle are mixxed by pulling fuel from both tanks. In Oklahoma we usually just have 87/89/91. 89 is a 50/50 mix of the 2 that you pay 15 cents a gallon more for then another 15 cents for the high grade.
Toluene..my octane booster of choice - SportsCarForums.com an interesting read for those that use octane boosters.

Not all gas stations have only two tanks, some have three or more, one tank for every grade of gas.
