Real World MPG with 5th Gen?

I would stop driving it until you figure out what the hell is wrong. Did you forget to tell us about the 10,000 lb sled you're towing?
I agree. If normal driving get you 6mpg it means there are few possibilities (assuming you don't have engine check light on):
1. someone is stealing you gas or you have a leak
2. gas you are driving is E87 or diluted with methanol a lot
3. you are driving with parking brake engaged
4. you are driving in 4L all the time
5. You are driving at 5psi in each wheel
6. Streets you are driving are covered with 12 inches of sand
7. you are driving uphill only and take the elevator going down
... and many more.

i drive with all the above and i average 33 mpg
 
City driving kills my gas mileage. Graph shows the relationship between the % of my miles that are highway miles (per tank) and the mpg I got on that tank.

The little dip at 52% highway miles was a tank of gas where I did a significant amount of idling. I'm carrying a little under 500lb of additional weight over stock. 285 C-rated KO2s.

If it is getting 1/3 the mileage it would be putting black smoke out and probably killed the CAT by now or soon will.
 
I've got a bone stock 2015 limited and i get about 14-15 mpg city, and about 16-18 mpg highway.

I drive about 8 miles (12ish minutes) to work and it is moderate traffic city driving.

unfortunately for me, i like going fast, so i don't drive in an "economical" way...

Does anyone have the MPG of a 5th gen with the new magnuson supercharger?

I was checking my milage with the Magnuson Supercharger, but then i woke up. :thumb: :loco:
 
2017 with 3" lift and 285s I am averaging 14.1 MPG with about 70% of that highway driving. *I have a lead foot.
 
I haven't gone back to read through this thread, but has anyone mentioned the "winter gas" mix? That could explain why some people are getting slightly worse gas mileage this time of year. We get that stuff here in AL and my MPG will go down by 1 or 2, when it's usually solid.
 
I haven't reset my mileage calculator in a long time, and commute on the locals in the Chicago suburbs, typically around 40-45mph with stoplights, and on Cooper Adventurer stock size tires I'm doing 18.4 mpg average.

Edit: I was at 18.6 last summer on summer gas.
 
Still breaking in but 2 weeks into the family, best tank was 12.3l/100k or 19 and worst was 14.3l/100k or 16. 75% HWY and approx 1200 miles
 
Update: 18' ORP. after putting on about 800 miles on the new toy I'm now averaging 17.8mpg using 87 octane and trying to stay within the "eco" range with pedal play. 60/40 highway/city.
 
I try to stay in the Eco mode but the display says I'm averaging 15.6mpg. My commute is usually during traffic time and I spend a less than 15min on the highway. I'm using Shell or Chevron 87 octane and warming up the T4R about 10min 4 times day before commuting.

I'm going to do the manual calculation on my next fillup.

How many miles do you have on your T4R? for the longest time I was averaging 15mpg until I started putting more miles on it.

It's a 2015 Limited with almost 27k on the odomoter. It's not much but I put roughly 30 miles a day round trip.

How many miles are on yours?
