Typically, motor oils stay stable and have a shelf life of up to five years. However, this stability can depend on a number of factors and it is always advisable to follow the manufacturer’s storage instructions. You must also keep a watch on the expiry date and refrain from using the motor oil once it has crossed that date. There are different types of motor oils available in the market such as synthetic motor oil, synthetic blend motor oil, high-mileage motor oil, and conventional motor oil. Their composition and the additives in them will affect their stability and storage capacity.
