Ethanol-free or Shell V-Power

[Johnmadd]

For what it's worth, unless you're running a custom tune to take advantage of it, if you're not experiencing any detonation on the typical diet of 93 octane you won't see additional performance benefits from filling it with 100... other than the weight savings in your wallet.

True.

93 Octane - no Ethanol Roughly $3.75 IIRC. $60 fill up

Same here. It's a small town, so I don't have to go to far out of my way , but it does take a bit of planning to be sure I always fill up on the right side of town. My car isn't fond of ethanol...
