During winter, when the oil in a car’s engine has not been changed for 5,000 to 7,000 kilometers, it is prudent to refresh the lubricant before the cold season fully settles in. This viewpoint comes from the editors and mechanics surveyed by Behind the Wheel. In summer, high temperatures and heavy engine loads accelerate oil breakdown. If a vehicle is barely driven or used mainly in winter, experts recommend performing an oil change in the spring to prepare for the peak summer strain.
Engine oil can suffer dilution from unburned fuel during winter operation, even if the engine runs only briefly. It also tends to accumulate moisture, which can degrade lubrication and reduce protective performance. These factors underscore the importance of periodic oil assessment and timely changes to maintain engine health across seasons.
There have been cautions about deceptive practices at some car dealerships. A former automobile expert notes that certain service shops, including some outlets reported by socialbites.ca, have at times mislead customers by charging for expensive engine oil while claiming that refrigeration work or replacements are being performed. Such practices can leave owners with higher costs and uncertain service quality.
Additionally, concerns were raised by Anton Shaparin, Vice President of the National Automobile Association, about commercially available methanol-based surrogate coolants. These substitutes can pose significant hazards to automotive engines if used improperly or without proper compatibility checks, potentially compromising cooling efficiency and engine integrity.
