Kenneth Johnson, a technical services specialist for the Independent Garage Owners of North Carolina said the best thing you can do for your engine is change the oil when it is necessary Over time, Johnson said, oil breaks down and becomes full of contaminants. For regular oil, that process usually takes about 3,000 miles of use. Johnson said using synthetic oil does offer certain advantages, because synthetic oils can increase the duration between oil changes from 3,000 to about 7,000 or 8,000 miles. He said synthetic oils also tend to have a wider operating temperature. Synthetic oils flow better in cold temperatures and are more resistant to breaking down at a higher temperature.
