How the Vehicle Benefits
Synthetic oil has several advantages for an engine. For example, the oil remains liquid and slippery over a wider range of temperatures. The benefit of that is better lubrication in cold-start and cold-running conditions, as well as more stable behavior under high heat. Also, synthetic oil molecules are of a more consistent size than conventional oil molecules, so they're better at maintaining the slick film that minimizes metal-to-metal contact.
You also can go longer between oil changes. Toyota recommends with regular oil every 5000 miles, with synthetic oil every 10,000 miles. Synthetic costs more but you get more miles between oil changes.
