Synthetic oil lasts longer in your car engine and will need changing less frequently for a number of reasons: 1 Being man made, there are no impurities like in conventional oils. 2 Synthetic oils are designed to be friendly to your engine with additives that prevent corrosion, and can work better in both hot and cold temperatures. 3 Additives these motor oils contain prevent breakdown and separation from occurring. 4 There’s less build up of sludge in synthetic oils, and they reduce the build-up of ash.
Why is it important to keep motor oil sealed?
When molecules in the air react with the molecules in the oil, it can increase the viscosity which forms sludge or sediment. Oxidized oil can also be more acidic, which may rust and cause corrosion to any metal surface it comes into contact with. In general, it’s better to keep any motor oil you may purchase sealed until it’s ready to use.

Most late-model cars require synthetic-blend or full-synthetic, low-viscosity, multi-grade, resource-conserving oils that minimize friction and maximize fuel economy. However, choosing the right oil is not always easy. The proper oil for your make and model of vehicle must have the correct SAE viscosity grade, meet performance standards set by the API, ILSAC and/or ACEA, and comply with any unique specifications established by the automaker or engine manufacturer. These requirements are detailed in your vehicle owner's manual, and your auto repair shop can provide information on your vehicle’s recommended oil specifications as well.

How does oil life monitoring work?
Most newer cars are equipped with oil-life monitoring systems that automatically determine when an oil change is needed and notify you with an alert on the instrument panel. Early simple systems are time and mileage based, but current advanced designs analyze actual vehicle operating conditions to identify when the oil will begin to degrade. In fact, the owner's and maintenance manuals for many newer cars eliminate "severe service" recommendations altogether because the oil-life monitoring system automatically shortens the oil change interval when it detects heavy-duty operation.
