I use to think that gas was just gas but not any more. Now that i know more about it and how it works it makes sense and now i get it.

I use to get quick trip gas because i thought since it gets more buisness it would have the fresh fuel but after a few data logs ive decided im not going buy from them any more. I tried a tone of different fuels and finally found a fuel my car likes and ive been running it for a few months now.

This is what bad gas looks

And this is what the gas im using now looks like

With bad gas you rknock sensor detects knock and retards your timming. Good gas you can really wind the timming up with no knock and it improves performance.

IMO its worth the extra money. You can do your own testing but ill bet you will come to the same conclusion. You may not really feel it but you can see with the datalogging what it is actually doing.
It's not important to win, it's important to make the other guy lose.
