Proper engine lubrication forms the cornerstone of vehicle reliability, directly influencing performance, fuel efficiency, and engine longevity throughout your GM vehicle's operational life. At Southside Chevrolet Buick GMC in Sudbury, Ontario, our oil change services go beyond basic fluid replacement to include comprehensive engine health assessments and preventive maintenance recommendations. Our Certified Service technicians understand that each GM engine has specific lubrication requirements based on design, operating conditions, and performance expectations. We use only premium oils and genuine GM filters that meet strict quality standards.
Modern GM engines incorporate advanced technologies that demand high-quality lubrication to function properly and achieve their designed service life. These sophisticated powerplants feature precise tolerances, variable valve timing systems, and direct injection technology that require specific oil formulations to prevent wear and deposit formation. Our oil change service includes careful selection of the appropriate oil viscosity and additive package for your specific engine, considering factors such as climate, driving conditions, and manufacturer recommendations. This scientific approach to lubrication ensures your engine operates within optimal parameters.


Every oil change at our facility includes a thorough multi-point inspection designed to identify potential issues before they develop into costly repairs. Our Certified Service technicians examine fluid levels, check for leaks, assess filter condition, and monitor engine performance indicators to provide a complete picture of your vehicle's health. This comprehensive approach allows us to recommend additional services when needed and helps establish a maintenance schedule that maximizes your vehicle's reliability while minimizing unexpected breakdowns. We maintain detailed service records for each vehicle, enabling us to track maintenance history.

Most vehicles require an oil change every 5,000 to 8,000 kilometres or every six months, but many newer GM models equipped with the latest engine technology can go up to 12,000-16,000 kilometres with synthetic oil. GM's engineering team has optimized its engines for efficiency and longevity, with many models featuring advanced engines that benefit from premium synthetic oils. Turbocharged engines typically require more frequent oil changes due to higher operating temperatures.
Regular oil changes improve engine performance and efficiency by reducing wear and tear on critical internal components. Proper oil maintenance is particularly important for GM vehicles, which are engineered for reliability, to preserve the sophisticated valve timing systems and technologies found in modern engines. Direct injection engines are particularly sensitive to oil quality due to their high-pressure fuel systems and precise injector tolerances.
At Southside Chevrolet Buick GMC, an oil change typically takes 30 minutes to an hour. Our Certified Service technicians are experienced with GM's unique engine layouts and access points. Different models have specific oil filter locations and drain plug designs that our technicians are familiar with. During this service, we also perform a comprehensive multi-point inspection as recommended by GM, checking critical systems beyond just the oil change.
Skipping oil changes can lead to engine sludge buildup, reduced efficiency, and increased wear on engine parts, with GM engines relying on proper lubrication to maintain their performance characteristics. Over time, neglected oil changes can cause severe damage to precision components like variable valve timing systems and turbochargers found in many GM engines, with turbocharged models particularly vulnerable to oil-related issues due to their high-temperature operation.
Synthetic oil is recommended for most modern GM vehicles and is specified in the maintenance requirements for many models, particularly those with turbocharged engines. It offers better engine protection in extreme temperatures, cleaner performance, and longer intervals between oil changes. Its resistance to breakdown and superior cleaning properties help maintain the precise tolerances modern engines require.
Look for signs like a dashboard warning light, dark or dirty oil on the dipstick, or unusual engine noises like ticking or knocking that may indicate insufficient lubrication. Many newer GM models have oil life monitoring systems that calculate change intervals based on actual driving conditions rather than simple mileage. The sophisticated engines in hybrid models have specific oil requirements and monitoring systems that our Certified Service technicians are trained to service according to GM's standards.
