Yes, anything mid 80's and up can be switched between conventional oil and synthetic oil. Anything older (that was around when zinc was found in oil, or when cork gaskets were used) should stick to conventional oil. It's actually federally mandated that conventional and synthetic oils be interchangable.
Conventional oils are derived from natural crude oils and contain small amounts of additional elements & impurities such as sulphur and hydrocarbons. Synthetic oils, being made in a laboratory, do not contain the same impurities thus synthetic will run cleaner through the engine. Cleaner engine means less build-up thus fewer oil changes are required. Additionally, with the absence of those impurities, the oil can flow more quickly throughout the engine regardless of the temperature. While synthetic oils do cost considerably more than natural oils, fewer trips to the mechanic means more savings in the long run. The recommendation for standard oil change is approximately 3,000 miles while synthetic oils can run for 5,000 to 10,000 miles.
