Winter cold killing everyone's MPG?

Yep, a credit card works in a pinch.

Started on a new project just before winter so cold here lost 7 mpg off average. Time to block 3/4 the radiator off.

I actually see some folks reporting a better mileage in cold weather, believe or not.

Isn't it summer there?

Yes, it's summer here by now, and yesterday my mom basically dragged me to the beach, but a few months ago when it was still winter here I had a talk with a guy who owns an 8th-generation Honda Civic and he told me he actually feels a very subtle increase in fuel-efficiency when the outside temperature is colder (not freezing, yet still cold) or when there is more moisture in the air. Since those conditions would allow the engine to remain on its ideal operating temperature while leaning the mixture, that makes sense.

My experience has been that temperature has a near linear relationship with economy, except for when the A/C needs to come on.

There is some commercial for a knife sharpener that would supposedly sharpen a credit card enough to slice through a tomato. I keep wondering about keeping an expired, but sharpened card in your wallet.

"Okay mister, I am going to hand you my credit card slowly. Gently... gently... take that you dirtbag!"

Would a sharp credit card clean ice better?

Maybe. But they'd tear up easier, and maybe cut your fingers. But you'd be wearing gloves, right?

Those with a debt work best. At least it would clear the debt of forgetting to put an ice blanket over it when you parked it

It’s part of the annual average, so that below average doesn’t really mean much since total miles have already been reduced, and remaining miles driven at a higher skill level.

But here’s something all of you need to consider. Coolant temp has next to nothing to do with “warm-up”. Engine oil temperature is that determinant. That’s the number to pursue.

After that is other fluids, greases and tires. The latter take 1.5-hrs to stabilize in warmish weather at steady state highway speeds.

Around town is pretty much only ever going to be a partial warm-up. Winter is simply a slower warmup.

Build a garage. When cars were new that’s what men did before a car was bought. They had the right order in that.

-4f Temp here right now don't think a unheated garage would help to much right now. getting
15.5mpg @ 35
23. mpg @ 40
32. mpg @ 45
33. mpg @ 50
Thinking cvt needs a bit more heat this should be the other way. lol
