How many MPG do you guys have on your S2Ks...... And how many miles you guys can do per tank until the fuel light goes on?? Do u guys put 87, 89, or 91 octane??

im currently using 91 and do around 250 miles per tank until the fuel light is on...

 

Since day one, I've been using Shell 91 and I average 260 a tank...

 

isn't 91 the minimum anyway? 270 /tank, avg 24 mpg.

 

24, and i drive pretty hard

 

I average about 19MPG, and I use Chevron 91 octane.

 

93 octane here, usually around 25 mpg.

 

I have never got above 21 mpg. I average 17-19 mpg, usually closer to 17, sometimes 16.

 

93 or sometimes 94 I avg between 25.5-26.8. I actually got about 330 to a tank a couple of times. What's odd is that at first the car was struggling to get 280 per tank then right berfore my firsy oil change it just went up. I figure maybe now it's broken in.

 

Still on my first tank. Looks to be low 20 right now. Hope it goes up as motor breaks in. One thing I noticed was the gas guage moved very slowly from full to half then just drained like a stuck pig the rest of the way.

 

Haha, yeah. That's why I don't like our stock fuel gauge.
