Cold weather can impact your car’s performance, so it’s essential to prepare it for winter conditions. Key steps include switching to winter tires for better traction, using low-viscosity engine oil for easier circulation, and waxing your car to protect against salt and grime. Replace windshield wipers with winter blades, inspect belts and hoses for durability, and ensure antifreeze levels are adequate to prevent engine damage. Keep your gas tank at least half full to avoid condensation and have an emergency heat reserve in case of unexpected delays.
