One and ONLY gas mileage thread please

My driving (and AC) habit were the same between the two runs.

AC doesn't make a noticeable difference in mileage anyway.

12.6 real world number not computer. Daly driving on 93perf around 47k miles

keep us posted. I would like to do a 93 perf tune but don't know if the mpg will be worth it vs the 87perf tune.

I use e-30 and it rocks

I do not think so. Keep in mind with this graphic... I have used way less 93oct than 87oct and that it has been these past few months when around here school is out. There's way less traffic so with my usual driving conditions the 87oct mpg would move towards an 11.6 and the 93oct mpg towards the 11.0

Of course if I ran e-30 things would be way different lol

 

[scarrjack]

Ya, I hear e-30 rocks

Let me tell you. It does. It really does.

Before I read through 125 pages of posts, has anyone experienced better mileage on higher octane with no tune? My dodge friend swears his mileage more than Pays for the better fuel but at $5.88 per gallon I'm skeptical to even try. On top of that our supreme is only 91 octane.
