Why Winter Is the Worst Time to Skip an Oil Change
Posted On: Monday, February 2, 2026
It’s easy to take an “out of sight, out of mind” approach to car maintenance. Who really has time to keep track of when they last had their oil changed? It may not be at the top of your mind, but an overdue oil change can cause sluggish starts and long-term engine wear.
Cold Weather
Winter weather and aging oil are individually harsh enough on your vehicle. Together, these factors put undue stress on your engine. Most vehicles require new oil every 4,000 to 6,000 miles, although individual needs can vary.
As oil ages, it can become thick with debris, preventing it from lubricating your engine properly and reducing fuel efficiency. An unlubricated engine will eventually seize up, necessitating expensive repairs.
Just as cooking oil pours faster when heated in a pan, motor oil flows better in warm environments. Conversely, motor oil thickens in cold weather. If your oil is already beginning to congeal due to contaminants, cold weather can become a death blow.
Understanding Oil
Drivers may shy away from oil changes because they don’t understand the process or the necessity. Experienced mechanics can help drivers create an appropriate plan and explain all of the options. Common points of confusion include:
- Oil Change Frequency: Many sources recommend different intervals between oil changes. For a long time, professionals recommended oil changes every 3,000 miles or three months. Modern vehicles can often go longer between changes. Most professionals will suggest oil changes every 4,000 to 6,000 miles, or 5,000 to 7,000 miles. Ultimately, the interval recommended in a vehicle’s owner’s manual will be the most accurate.
- Oil Grades: Oils are graded based on their viscosity (how thick they are and how they flow). Most drivers should use the oil recommended in their owner’s manual. Drivers who regularly encounter extreme temperatures or heavy loads might consider using an oil grade better suited to their needs.
- Synthetic or Conventional Oil: Synthetic oil is engineered specifically to work in an engine. It can handle higher temperatures, lubricates better, and lasts longer than conventional oil. Synthetic oil is more expensive, but mechanics typically recommend it over conventional oil.
