Just wondering what everyone is getting for gas mileage for the winter with winter blend gas ?

2.4l FD1

Averaging 18mpg

2011
2.4L CVT
FD1

I run around 24 MPG for my average mix of driving( about 70/30 city to highway )during the non winter blend fuel months. When winter blend fuel hits here( approx Oct - April )it drops me down to around 20-21. Definite drop due to the winter fuel.

It isn't the cold the way so many claim ether because it doesn't get really cold most years until at least Dec here and by March we are warming back up again. MPG takes a jump every year when it goes away in Spring and then it dives when it comes back in the Fall and temp is not a factor at either time. I can see it fall/rise in my fuel log and as said temp is not the factor. It is the swap from winter to summer fuel.

However, with that all said, it has been so damn cold here that I have actually been using my remote start and it has effected my MPG even more. My Dad is 89 and can't handle going out to an unheated car when it is 2 degrees so I have to give it at least 5 minutes to get it warmed up some. The heated seats take care of the rest when he gets in. So that extended warm up idling really hurts. Just the extreme cold hurts some too. I am down to about 19 MPG now for an average tank and it sucks. Come on April.

That's is where I get the gas mileage hit. I warm up mine for about 6 minutes every day going to and from work. I also live 8 minutes away from my house so its all stop and go traffic and no express way driving.

Here with the highly polar canadian winters, my consumption to double I left $ 30 / week and I'm at $ 60 / week for the same path. But I have to do the car warmed 5-7 min before otherwise would have the mechanics does not like the cold.

25.5 and I hope it goes up with summer blend, which I haven't had a chance to really run yet. Our other car REALLY drops with winter gas. From 28+ to around 24-25, if we're lucky. Missing some 'kick' to it too.

21.5 according to the dash right now. I checked it twice by hand and it was close enough to accurate for me. Hoping it does a little better in spring going; I am sure the all seasons will help out too

25 - 26 mpg, down from an overall avg of 28 and summer averages of 29 - 30mpg. Mostly highway driving for me though with little warm up just a few seconds to let the oil get moving then I gently move along gradually increasing speed. I have about a mile of secondary rds before I hit the expressway.

FYI, I was up very early on that cold cold night a few weeks back and she started right up at -16 according to the dashboard temp gauge and quite a few - 9 or -10 mornings as well.

What exactly is "winter" gas/petrol?

It is formulated differently for emissions reasons( has to do with how fast it evaporates - RVP value or something like that - I forget off the top of my head ). It is even worse in places like CA and New England. In those areas the fuel also contains oxygenates and other emissions additives as well that can further hurt fuel efficiency.

The bottom line is winter blend fuel has less energy as a result and you get less MPG. I think it is something like 2-4% less energy and thus the MPG drop with winter fuels.

You can learn more about this than you would ever want to with a simple search on the internet. Just type in something like what is winter fuel.

Thanks NYPatriot. Yes, I started a search after I posted, which resulted in the headache I already had getting much larger. And I thought ethanol additive info was troubling...
