Winter vs Summer

[MBrown]

How much does the seasonal temperature change actually effect how much power your engine makes and your mpg?

I get shittier MPG for sure in the winter, my gas gets guzzled every time I start the engine when it's super cold out. I also noticed that I don't get any better MPG with premium vs regular so I just pour in the cheap stuff winter time.

the winter blend of gas is formulated to create less / break down more pollution in the cold winter air. this gives a little less power than the summer blend.

My drive to work is about 27 km one way. In the morning if there is heavy snow, bumper to bumper traffic on the highway almost all the way there, I shit you not almost half my tank (35 liters) of fuel will get eaten. It's about a 1.5 - 2 hour drive.

Since gasoline doesn't vaporize well in the cold, extra gas is added until the engine reaches operating temperature.
Otherwise the cay would run poorly.
It's like the choke in older cars, but done electronically now.

If your state does winter blend gas, it's about a 10% reduction in MPG, from my experience, and those cold starts suck up gas like there's no tomorrow.

Yup. I get 36 in the summer, but 32 in the winter.

I drive a 4.7l V8 in the winter and a 2l 4cyl in the summer...so my difference is pretty drastic.

I was thinking it had more to do with the temperature.

That explains why I enjoy driving more on summer than in winter.
