Synthetic oils are rather unique: They will definitely last much longer than natural oils (hydrocarbon oils). The best way to identify when it is time to change oil is by color. Most synthetics, such as Mobil 1, are a slight amber when new. They will hold their color fairly well during their lifetime. When they start to deteriorate (breakdown), the color will begin to rapidly darken, almost to a hydracarbon oil color. My recommendations are to change them before the color change. Of coruse, drviing conditions will have significant influence. My plans are around 8,000-10,000.
