Winter gas mileage vs summer gas mileage

I know I know, there has been many threads related to this but their all old lol. I wanna see what you guys get in the winter vs summer. We get at least 30-50% increase in gas mileage in our 09 Camry.
- It has around 217k km
- 10-12L/100km in the summer
- 15-19L/100km in the winter
- 11 km one way Mon-Fri

when a car is cold it takes energy to heat up to operating temps, therefore using more gas.

I don't dwell on such things anymore... the vehicle will consume what it needs to consume as long as it gets me where I am going and it will keep me comfortable(warm/cold) over the duration of the ride.
one more deal and I'm out * involuntary tick*.... :twisted:

That's a huge difference. My 10 Fusion gets 1 or 2L/100 less in the winter. Usually 9 in the summer and 10 or 11L/100km in the winter. 10km trips usually. The engine seems to warm up fairly fast in the winter unlike the 2000 Intrepid it replaced.

My mileage goes up about 40% more in winter.

Gas is cheap lately so not much more pain at the pumps plus no where to go and nothing to do lol.

Not in till Trudeaus carbon tax reaches $170/tonne by 2030, apparently it will be like extra 45cents/L

Your last thread on this topic was only 6 weeks ago: higher-gas-mileage-2415129/2/#p33384556

And 9 months since the thread before that: car-used-too-much-fuel-2358683/

I wouldn’t call these old threads and I can assure you that nothing has changed in science, engineering, physics, etc since then.

Here are the main factors:
— winter gas blend reduces mileage
— using remote start more often and/or longer reduces mileage (zero mpg)
— starting in cold weather uses more fuel
— cold engine idles at higher rpm until warmed up (and takes longer to warm up) thus using more fuel

You cannot compare your Camry directly with your Altima unless it is remote started at the same time every day that the Camry is remote started, and they both need to idle the same amount before driving off, and they both need to do the same commute at the same time of day, and with the same number of passengers.

You’re probably not going to get any different answers from the last 2 times you asked about this. The only thing that I think might not have been mentioned yet would be to get a full computer scan done on the Camry with a scan tool that is able to scan for both the generic codes that might be thrown as well as any Toyota-specific codes that might have been thrown. If there’s no codes at all, then it is what it is. Otherwise, maybe there’s a code thrown that points to a needed repair(s).

And this comes as a surprise?
