It's important to use the recommended type of oil in your Corolla to ensure optimal engine performance and longevity. Using an oil with the wrong viscosity or additives can cause damage to your engine.
In addition to the recommended oil type, it's also important to follow the manufacturer's recommendations for oil change intervals. The oil change interval for a 2009 Toyota Corolla is every 5,000 miles or 6 months, whichever comes first. However, if you drive in severe conditions, such as in dusty or hot environments, you may need to change your oil more frequently.
