I'm not sure what the minimum octane is for the X or whether the published MPG figures are acurate. Just wanted to get a general idea of what everyone's actual mpg and generally used gasoline octane....

I use 87 and I am getting about 17. That is after the compensation for the tires. Before the lift and tires I was getting a solid 19+.

Stock tires, slightly modified exhaust and K&N drop in filter. I made a 380 mile trip over the weekend with the X loaded down with kid stuff and wife stuff.

I got 22.7 mpg with 87 octane! No foolin'. About 1/2 divided highway, the rest 1 lane each direction with slow downs for intersections and small towns.

The owner manual says
Use unleaded regular gasoline with an octane
rating of at least 87 AKI (Anti-Knock Index) number
(Research octane number 91).
Here in Texas the lowest octane I have seen at the pumps is 87, I made a trip to Colorado and there the lowest octane was 86 so I used the middle grade.

I only have 1100 miles on her and I am getting solid 18's and a few times 19. I am sure this will get better as I get past the break in period. I also think we have switched to winter gas up here already.

I wouldn't believe it either if I wasn't the one putting gas in it. Filled up today, regular running around town 21.9. Only been on one highway trip, and that wasn't even a full tanks worth of driving. 24.9
