I drive about 38 miles each way to and from work, all highway with speed limits 65 to 55..and all pretty much level ground (there isn't many hills in the desert valley in AZ) if I drive conservatively I get about 27 mpg one way and about 25 coming home.

 

i usually get 20 - 22 mpg and thats driving all over.

 

Same here, I got 310 as well, so that's basically 23.8 mpg and I was just cruisin 62-67ish mph.

 

lol the most i ever got was 280 for one tank but i bosted a couple times, couldnt help myself lmao

 

with my basic bolt on's and such I just took another roadtrip and got about avg 24 mpg, with A/C on people in the car and trunk packed with luggage. If I don't get on it I can usually stay within the 23-26 mpg range cruising

 

9 on mine

 

i have basic bolt ons and a tune and im getting 15mpg. . i dunno how the f you guys get 24+...

 

I somehow get about 250 miles on the tank. I get on the boost at least a few times every time i drive it. I drive it daily. I used to get 280 to the tank on the stock turbo driving a similar way.

I actually broke the 30 mpg barrier a couple weekends ago. I got 30.399 mpg to be exact on my last trip to visit my family ~110 miles away, though given the circumstances that day, I could've done a tad better, as there were a few spots of traffic. The time before that, I had hit ~29.1 mpg making the same trip a month prior.

Breaking the 30 mpg mark took a ton of patience, as I was doing around 60-65 mph the whole time. I don't like driving that slow, but I just wanted to see what I could do since it was me by myself. (I usually pick up my brother on the way, who lives halfway between me and my parents, but that adds a good 160 pounds along with whatever he brought home with him, like his personal belongings and dirty laundry, so I usually don't go for the high mpg tests when he's with me.)

 

LOOOOL

btw thats awsome that u hit 30mpg, thanks for sharing

 

^ Haha, no problem. The problem with me is that I always want to test how high of mpg I can get. While I did break the 30 mpg barrier, like I said, I'm pretty sure I could've done better, so since I'm ADD I may have to try it out the next time I go home without my brother, assuming I leave early enough in the morning to dodge traffic and not need A/C.

 

I get between 19 and 22 mpg no matter how I drive for that tank.

 

So i did another long trip this past weekend, and with my current fp red/S2/bolt ons this is what I achieved

average speed 85mph
hitting boost in 5th gear every 10 mins or so up to 6psi when passing others
25.6-27 mpg with a fully loaded car.

 

Winter - 21- 22 Mpg
Summer - 22-26mpg

I get 320 miles to a tank in my 8 MR, all highway.....
