MPG Differences for Hybrid, warm to cold, WHY does your MPG drop?

[Little boy blue]

Phew, I was afraid rhis was another thread where someone is asking why fuel mileage goes down in the winter! Not that there is anything wrong with asking a question, of course.

Thanks for the write-up, and I didn't have to do one...yet...night is still young though, eh!

We don't have to many real cold days in Florida but I noticed the difference in my MPG when it gets below 65°F normally I will see 42mpg but when it's cold out I'm seeing 36 MPG.

Most definitely, cold takes a toll on fuel mileage!

Here is this morning's weather in Southern Manitoba. The sky's colour at sunrise is just beautiful here in Big Sky Country today.

-25 Celcius is -13 degrees F. Not including the windchill of course.

It was a bit colder yesterday morning but not terribly cold yet...and driving here when it is cool like this we are getting about 26-28 mpg (US 3.78 liters) with our hybrid when we drove, and that was mixed driving of 75%highway, 25% city.

Still waaayyyy better then our last F150 with the 5 liter engine...it would be at 12 or 13 mpg (US gallan or 3.78 liter).

When it gets really cold here, the mileage will drop a bit more of course. It's the highway driving that does it in.

It is temperatures like this where you start to see Dodge and Chevy trucks with cardboard zip tied in front of their grills because they don't have automatic louvers (like we have!) in front of their radiators and they are desperate to warm their trucks up any way they can! That has to suck in this day and age...just admit it is a good idea and put them in.

I have done this as well, but not for many, many years.

Have a good one,

Andy
