10% Ethanol vs. Ethanol Free Gas

Stino · 11-24-2012, 11:37 AM

Please offer your opinion on this topic. I know there's been some Ethanol discussions on the forum, nevertheless, not specifically what I'm asking. So anyone with a very good understanding of Ethanol's characteristics and how it effects the car ability to perform at peak performance and overall internal functions long term, please chime in. Thanks in advance!

Okay ... taking into consideration PERFORMANCE and WHAT'S BETTER FOR OUR 370Z OVERALL. The latter being very important.

Deciding Facts below:

1. I have a local Exxon/Mobil Gas Station that offers 90 OCTANE ETHANOL FREE GAS AT A PREMIUM OF $4.05.
2. Compared to a local Sunoco Gas Station that offers 93 OCTANE WITH 10% ETHANOL FOR A PRICE OF $3.65.

My question: Is it better to run 90 Octane Ethanol free gas vs. 93 Octane w/ 10% Ethanol?
