Extreme Cold

Difference in mpg? Probably the extra time warming up from the remote starts consuming a bit more fuel.

I reset the mileage after heading out to adjust for that. I think the air was so dense the "brick" had more trouble than usual at speed. It never got warmer than the minus teens until close to home. The wind noise and more than usual shifting out of 8th were typical of driving into a signifiant headwind. I had the cruise set on 70 and have done enough trips to know that no wind mpg at that speed is around 20 and headwind mpg drops to around 16. I was showing 14. I thought maybe I was losing my mind because chimney smoke was going straight up and flags were limp.

That's it. 14mpg is unacceptable the 1 week a year I road trip it in those conditions. The diesel won't work so I guess I need to get a 392!! It will stay in 8th.

Colder temps also means longer periods of cold and thicker viscosity for oil and drive-train oils and fluids.

You burn more fuel keeping the engine at stoichiometric temps, the air is denser and also colder hitting the radiator. I see a considerable drop in range anytime the temperatures drop below about -10C. Almost made me consider swapping my JT grill out and back to stock. I suspect a bit of cardboard covering part of the radiator, or the old fashion radiator blankets would help.

Cold Cold Cold like an ice cream cone here in SoCal. Had a low of 45 this AM but warming up to 72. Should be 80's next week.

Where is the unlike button

For reference, it's currently -13C here. I'm averaging 13.5 - 14l/100km

and I don't need to drive my JLR and my Golf S averages 34 MPG A 75 MPH

That's well above freezing still. 15C! I'm not sure if you'd see a significant decrease in range at those temps.

Another to remember is (depending on where you live) gas is reformulated in the winter and you lose milage to that as well.

You would think a properly working thermostat on modern engines is adequate for regulating operating temps.

Here's my weather forecast in south Florida- 80 today but some very cool nights heading our way-

From all of us in the freezing Midwest....???

I try my best to plug in the block heater anytime it is below -10C/14F since it is parked outside. Around -30C/-22F it sometimes makes a squealing sound on cold startup... no idea what it is but it goes away.

but pretty much the frigid temps just wreck your fuel economy. very common for any vehicle. On very cold days I get around 16.5mpg.

Block heaters dont need to be used unless its less then -20C.

In colder climates they put additives in the gas (winter gas) and it gives you worse mileage.

I ve had no squeaks or any noises up to -35C so far

The Midwest where we are is in the corn-belt. Lots of ethanol blends. We have winter gas blend here also. I remember a 10%-15% difference in mpg difference running winter blend.

and we are at 1.50/liter right now. was 1.10/liter when i picked it up in Oct. ya carbon tax
