When temperatures drop across Whatcom County, your vehicle works harder than you think. Cold weather affects gas, diesel, and electric vehicles differently, but all of them experience added strain during winter months.
Understanding what happens under the hood can help you avoid unexpected breakdowns and costly repairs.
How Cold Weather Affects Gas Vehicles
Gas-powered vehicles rely heavily on battery strength and proper lubrication.
In cold temperatures:
• Engine oil thickens, making it harder to circulate
• Batteries lose power and struggle to start the engine
• Fuel efficiency decreases
• Short trips prevent the engine from fully warming up
If your battery is already a few years old, winter is often when it fails.
How Cold Weather Impacts Diesel Vehicles
Diesel engines are built tough, but winter brings unique challenges.
In freezing temperatures:
• Diesel fuel can gel without proper winter treatment
• Glow plugs work harder during cold starts
• Batteries are under increased strain
• Fuel systems need to be properly maintained
Winterized fuel and preventative maintenance are critical for reliable diesel performance.
What Happens to EVs in Cold Weather
Electric vehicles are also affected by low temperatures.
You may notice:
• 10–30% reduction in driving range
• Slower charging times
• Increased battery usage for cabin heat
• Reduced regenerative braking efficiency
Cold weather doesn’t damage EVs, but it does change performance and efficiency expectations.
Systems That Suffer in the Cold
Regardless of what you drive, winter impacts:
• Battery performance
• Tire pressure (which drops as temperatures fall)
• Fluid levels and viscosity
• Belts and hoses
• Brakes and suspension
Staying ahead of these issues prevents emergency repairs.
