Debunking a Winter Driving Myth: Your Gas Tank Doesn’t Need to Be full to Prevent Freezing
DENVER – A widely circulated winter driving “tip” – keeping your gas tank full to prevent fuel from freezing - is largely unneeded, according to experts at AAA. While a fully empty tank could theoretically lead to issues, gasoline itself won’t freeze unless temperatures plummet to a frigid 50 degrees below zero.
The real concern isn’t frozen gasoline, but frozen water. Condensation naturally forms inside gas tanks, and this water can enter the fuel line and freeze, potentially preventing a vehicle from starting and even damaging the fuel system. This is particularly relevant as winter temperatures descend across much of the contry, leaving drivers vulnerable to unexpected breakdowns.Keeping a sufficient level of fuel in the tank minimizes the space available for this condensation to accumulate, mitigating the risk.
Skyler McKinley of AAA explains that the gas itself is highly resistant to freezing. “Gas can’t freeze unless it’s well below freezing, when temperatures hit 50 degrees below zero,” McKinley stated. However, maintaining a reasonable fuel level is a proactive measure against water-related issues.
to avoid potential problems, McKinley recommends keeping your gas tank at least a quarter full throughout the winter months. This simple step reduces the area where water condensate can form and safeguards against a frozen fuel line. While a full tank isn’t essential, a partially filled one offers a practical layer of protection against winter’s chill.
