Official: What are your real world MPG Numbers

[Coolbreezin]

i have a 2017 1.4 turbo. If i drive like a typical 4 cylinder and stay below 70mph, i stay at 30mpg.

 

[Meekster]

Estimated MPG

I am averaging about 32 mpg combined road and city. Most of my driving is highway driving.

 

[cdots33]

I have a stock 2012 LTZ 6MT Turbo and I average 37 MPG. I commute 43 miles one way with a couple traffic lights. I usually drive between 55-60 MPH.

 

[JTee2017]

So far, with 2017 1.8L auto, averaging about 30.2 MPG hand calculated in combined driving around town, semi rural and a bit of freeway.

The best highway/interstate short trips of about 100 to 150 miles was 36 MPG hand calculated driving 55 to 65 MPH. This was with only about 800 miles on the odometer. Now at almost 1,800 miles.

35-36 mpg calculated 2015 sedan 1.8 automatic about 80 miles a day rural backroads 55-60 mph with a once a week expressway 70 mph run for about 30 miles.

So i did a test recently on how much of a difference gas mileage is at 75mph compared to 85 (manual RS) on the toll road that I take to work. Dear God it's a huge difference. At 75 I was averaging about 29.5 mpg and at 85 it dropped down to 23.3. However the tune and front splitter will cause a difference from the factory numbers of course but I was surprised at how big the difference was

I got gas just before hitting the highway the other day, so I reset the DIC to do an MPG test. Around 41MPG for 30 miles in pretty ideal conditions: 65-70MPH, 50 degrees (no A/C), flat road, little traffic.

My last 5 tanks have topped 40mpg as calculated in an Excel spreadsheet. Lot's of 55mph county highway driving though.

45.9 according to the DIC on its fourth birthday

2013 LS sedan
1.8 5 speed

 

[OssiansFolly]

A whopping 24mpg on this tank. But that isn't a fair number considering I live in Cleveland and remote start my car with the defroster almost every morning.

 

[Crumbi]

I sit around 25. It is fun to watch the miles per gallon estimate on the car slowly tick down .1 miles a gallon every so often while it catches up to my actual.

Best so far on e85 I can get love driving this car 29mpg

 

[ChicksHateMe]

I still use fuelly to track mine. I think it's pretty good considering I'm about 70/30 city in a hilly area and terrible winters.

I could do a lot better, but it's way too fun to drive this thing, so I press that pedal on the right too hard and too often....

 

[jackgopack4]

Average of 35.4 over almost 3 years. About 60/40 highway

Just got done with a 1400 mile trip from Texas to Michigan and was pretty amazed at how much driving in warm weather can help with MPG numbers.

Through Texas I was getting about 39mpg while driving around 79-84mph (no AC w/sunroof cracked)

Driving through Indiana (no AC/no heat) on similarly flat and open roads I was getting around 34mpg at same speeds.

In summary, I'm moving to texas.

Is it possible it has to do with elevation? Combustion engines would need less fuel at higher altitudes

2013 1.4 turbo auto with about 20,000 miles on it, 29.8 combined, My wife drove from Minnesota to Arizona and did not reset the avg miles per gallon. She using the cruise most of the time and driving conservatively (usually the speed limit) was getting 53 mpg and still climbing by the time she got here. When the car was new (less than a 1000 miles on it) we took it on a 300 mile trip. I reset the MPG and got 43.9 might still have the picture if needed. Didn't think to take a picture of the 53 though.

 

[WearyWeasel]

When I use cruise control my MPG decreases significantly.
Without cruise, my commute is about 25 miles each way at a mostly steady 65mph.

32MPG. 29-30 if I'm driving like an ass. 32-34 on a long highway trip from NC to PA.

I expected a little better when I bought it. ):

Edit: And after running different octanes, 87 and 91/93 seemed to perform equally while 89 actually gave me a bump of about 3 MPG. I'm going to keep testing for a larger sample size but I'm intrigued.

 

[Turbonic]

Dang, I get on average 28-30 mpg cruising on the highway at 70-80 mph while pulling a small trailer with my motorcycle on it, about 36 on the highway unloaded, and around 30 in the city unloaded. My car loves to cruise at speeds in the mid-80's
