lol, it doesn't matter. I get the same mileage in 100*F summer as I do in 10*F winter.And the winter MPG threads start! They go away with warmer weather.
- Winter blend gas is less energetic
- Cold engines use more gas as they warm up to temp
- Winter weather is often windy; wind has a big effect on mpg
- Tire pressure might be off spec
Meanwhile the EPA ratings...
- Conducted around 70 degrees in a lab
- No headwind
- Use pure gasoline and not a blend
- May have a different idea of 'city' and 'highway' driving...
How long do you warm up your car for? I drive a mix of highway and residential roads (near KOP area), and average around 20-22. I also use Wawa gas (I haven't heard the best things), but I usually warm up until the RPMs drop a bit, so maybe like 1-2 minutes max.
Yup, mpg threads are very common around this time. I average around 27-28 and 40/60 hwy/city. You should absolutely not be hitting lower than 20 in the cx5 though. No matter the weather. Unless your trip to work is just a couple miles away, and you let your car warm for 10 minutes before driving. That's another reason though winter always brings out bad gas mileage. As if the weather doesn't hurt mpg enough, remember that idling your car to warm it up tremendously hurts gas mileage.
16 Mile Commute. Two lane roads. Light traffic in morning, moderate traffic in afternoon. 27 MPG. Highway (Interstate) 31-32 MPG. Very happy with fuel economy

Only getting 23mpg combined city and highway driving since we bought the car new almost 4 years ago.
Working in Phoenix AZ right now and my hotel is 6 miles from where i work, all street. Was averaging 28+ Mpg with mobil 1 AFE. Went to a dealer here to change my oil and requested for Mazda with Moly. About 1,000 miles after oil change, I am averaging 30.9 mpg....
Maybe wind. I've done as badly as 23mpg highway for several hundred miles before when there was 10-20mph wind gusts.Just took another round trip from Houston to San Antonio. The drop in gas mileage is significant from summer to winter for my CX-5. Last summer I was getting in the 40's. If I remember right it was 43 to 45 mpg. This time my trip to San Antonio averaged 37 mpg. The return trip I got 34 mpg. So almost 10 less mpg. As I was heading out of Houston I stopped at Discount Tire. I had them air up the tires to 35psi. Maybe part of the difference is the tires. I had the original Yokohamas on the first trip.
In july I purchased new Yokohama tires. They were only sold at discount tire and made in the USA. I expected Japan. And they were rated a fuel efficient tire.
I have not noticed any difference in mixed driving though. I average 31.
I've run Mazda Moly and M1 AFE. No difference.
