GM Oil Life System(SATURN)

GM Oil Life System
The Ecotec designers said the engine utilizes an oil life system that reduces the frequency of oil changes.
The system, which notifies the driver of needed oil changes on the dashboard display, uses an algorithm that tracks engine revolutions and temperature and predicts oil life based on these parameters and driver use.

GM engineers report that with their Oil Life System, the average GM vehicle typically needs oil changes half as often as the 3,000-mile recommendation. Based on driving 15,000 miles per year, this could mean between two to three fewer oil changes annually.

As many of you who perform oil changes know, more than 97% of GM vehicles sold in U.S. are equipped with this Oil Life System. GM reports that there are more than 31 million GM vehicles on U.S. roads that are equipped with the system.

For those who are changing the oil on these engines, the Ecotec’s oil system design incorporates a cast-in oil filter housing, which eliminates the need to be under the vehicle to perform oil changes and eliminates throwaway oil filter cans that retain used oil.

Engineers said that synthetic oil is recommended for this engine.
