Average MPG Survey on USA 1.6 litre engine with Automatic Transmission

[2017 Ford Fiesta SE Sedan]

Hello Everyone!

I have a 2017 USA Model Oxford White Ford Fiesta SE Sedan with
the Automatic Transmission and 119,00 miles with the 1.6 litre engine.
I am keeping studless snow tires on the car during January, February,
and March of 2023 since I live in New York State. According to the trip computer, I am averaging 40.0 miles per gallon, and I think that the
readings are accurate based on my gasoline fill-ups using 87 octane
fuel. How are all of you dong with your average MPG?

My ST used to get 31-32 highway and high 20s in town. For some reason, my last highway trip I got 34, and I was going fast.
Guess it's finally breaking in.

I have a Hatch 5speed tho,
I have mixed driving. However mostly highway/rural. I have 2 routes I can take to town/work.
Summer...
On the divided highway cruising at 3000RPM I get 35mpg with air cond on and 37mpg with it off.
On the 2 lane at 55/60mph I get 37mpg with air cond on and 38mpg with it off.
Winter...
With the colder weather, snow and pre heating the car it drops to 33 on the big highway and 34 on the 2 lane.
I have mounted a space heater under the passenger side dash to do some pre heating of the interior and clear glass to help reduce idling time.
Over all, the car is doing its job of costing me less money. If I wanted better mileage, Id get a motorcycle...but winter commuting might be tough!!

Since I do a good amount of city driving, with only 8 miles on two highways, I get about 23-25mpg. Every night I drive, I spend an inordinate amount of time idling and inching for about a mile after the eastbound intersection of US-1 and I-76. One of these days I'm hoping to get my '72 diesel Benz fixed back up and then I'll have the option of driving that which gets 32mpg (of course diesel is more expensive than eggs now, so that's still not saving much if any.) I'm trying to ride the bicycle more, which is better for my body and mind.

You still have the ST wheels and tires on your Fiesta?
If so, that is where the 2 mpg went away to.

True. Wider and heavier. They corner well, though.

It was surprising that just changing out the wheels and tires had such a huge effect on the fuel economy and performance. I put the ST wheels and tires on my 2011 for a week, shortly after I got the FiST. The 11 Fiesta lost 2.3 mpg average fuel economy just from that one change. I bumped up the tires cold psi to 35 psi and average fuel economy improved ever so slightly to 2.1 mpg average loss.
I like the looks of the larger wheels. But,The road feel, fuel economy and cost of replacement tires doesn’t excite me at all.
I have never been accused of being unwilling to spend money on my cars. But, large diameter, often heavy wheels are not something that I will ever have a problem resisting the urge to get my checkbook out to purchase.

Where I used to live this was a necessity...So you're not alone in the thinking. Used a battery charger with this too to help keep the battery strong enough to turn the engine over.

Plug it in 30 min ahead to help warm the interior then unplug before starting the engine - still had to warm up but made those lake winters more bearable.

Hello Everyone,

Back on Friday April 19th in 2024, I was still averaging
40.0 miles per gallon when I reached 145,000 miles.
When I had my maintenance and service done on
that day by my local auto technician, he did the
following work:

Oil and Filter Change and Service
Removal of Four Bridgestone Blizzak Snow Tires
Installation of Four New General Altimax All Season Tires
Four Wheel Alignment
New York State Inspection

I reviewed my owners manual to see how much work
will be needed for the 150,000 mile service. I have
replaced a lot (but of course not all) of the components
on the vehicle to do as much preventative maintenance
as possible, to avoid reactionary repairs.

Would anyone know of a 2011 - 2019 Owner of a
Ford Fiesta Sedan in the USA with the 1.6 liter
4 cylinder engine and the 6 Speed Automatic
Transmission who has reached 150,000 miles,
and if they are averaging 40.0 miles per gallon?
