Calling all auto-engine experts

Ages ago, I got it in my head that it is easier to start a car on a cold day if the gas tank is full.

Can’t remember who told me that or where I might have read it. But apparently I believed it, because I have been filling gas tanks in advance of cold fronts for years.

Maybe it has helped. Or maybe not. In any event, car starting has not been much of an issue at my place except for a couple of times about 20 years ago.

So here’s my question. Is there anything to that theory?

I recognize that starting a car has changed in the decades since I first encountered that “full gas tank” advice. Today’s computerized engines do not require the same gas-pedal finesse that once was a prized skill in frigid climes.

So I guess my question needs a follow-up. Even if it doesn’t make a difference now, did it once upon a time?
