07 5.4L EB swb ~14-15mpg average. Hasn't seen higher than 17 or 18 mpg in about 100k miles. Lieometer is actually spot on accurate.

17 3.5L Plat EL Lieometer says 18.3 average, with a high of 21 if real careful. Hand calculating has shown a consistent ~1.2 mpg less discrepancy so I don't bother hand calculating anymore. So real mpg is about 17.1-17.5 mpg avg when I'm driving 80 mph on the highway. Even 5 mph less helps a lot. I get ~19 when I'm cooling it at 70-75 without traffic.

2017 XLT 3.5L twin turbo with 30K mi.
I live in FL always drive with A/C on and I have a VERY heavy foot. I drive it like my 350Z.
I never get less than 16mpg in the city and if I set the cruise at 65-70mph while traveling to SC on I-95 I have gotten up to 24 mpg. No mods of any kind.

Hello,

I was just wondering what is everyone's average MPG. Please post the model year, engine, mileage, as well as any mods or recent maintenance you've done to improve your MPG, or what mods/maintenance you intend to do to improve it. Here's mine :


Model : 2014 Expedition SSV

Engine : Triton V8 5.4L 3V

Mileage : 130,000

Current average MPG : 12.4

Mods : None

Recent maintenance : Synthetic engine oil (5W30), new air filter, MAF clean, throttle body clean, new drive belt with tensioner and idler pulleys.

To do : Spark plugs, transmission fluid & filter, transfer case fluid, differential fluid.



Thanks! :)

2019 Exp 3.5 Eco gets 23.5 on the highway and honestly it drops to 14-15 in town.

Model : 2011 Expedition EL XLT

Engine : 5.4L 2V

Mileage : 139,000

Current average MPG : 18.1

Mods : Gotts Mod, K&N Air Filter, Gibson 3" catback exhaust, canned X4 87 octane performance tune

Recent maintenance : Synthetic 5w20 (always synthetic), cleaned MAF

To do : Will be installing 2.5/1.5 lift and brand new Bilstein 4600 shocks on all four corners next month. Also swapping 275/55/R20 Bridgestone Dueler H/L Alenzas on stock 20" platinum wheels for more aggressive 285/75/R17 Cooper Discoverer AT3 XLTs on 17" Ford Raptor wheels (fully expecting loss in MPGs just due to the tire switch alone).

I have super short trips in my small town and have weekend highway trips at least 3 weekends a month. Still whenever I drive, you would think a grandma is behind the wheel so I can get the MPGs as high as possible.

Just got back from a 350 total mile trip and the computer said I averaged 21 mpg. Won't know actual till I get gas next week but if it ends up close to that I will be happy.

1997 XLT Expedition with 5.4L and semi aggressive Goodyear Wrangler Dura-Trac tires. I have three bench seats so it seats 9 people. Limited Slip front and rear differentials. I have consistently obtained 13.5-14.5 mpg depending on if I travel more then 65mph when on the highway. I've never gone under 13 even with a roof top X-Cargo carrier and the entire back filled with camping gear. I pull the rear seat for those occasions. Expedition is almost at 170,000. I call it my "Beast."
