How does weather affect vehicle performance?

Extreme temperatures significantly impact fluid viscosity, which is essential for the performance and operation of a vehicle. In cold weather, engine oil becomes thicker, leading to higher resistance in the engine components. This affects not only how quickly the engine can start and warm up but also how efficiently it runs. Conversely, in hot weather, fluids can become too thin, potentially leading to oil breakdown and reduced lubrication, increasing wear and tear on engine parts. Understanding the correlation between temperature and fluid properties helps technicians anticipate potential issues and ensure that vehicles operate optimally under varying weather conditions.
