Does motor oil expire?
Under ideal conditions (stored in the original, closed containers at moderate temperatures), motor oil regularly remains stable for an extended period of time. There should not be deposits on the bottom of the bottle. You cannot redissolve the deposits by just shaking the bottle. The oil needs to be replaced.
An engine oil’s properties are best if it is used within two years. After that, we recommend replacing the oil.
Do not throw the old oil in the trash. Oil should be recycled. Learn more here.
Please note that all these are mainly recommendations. You should follow the steps carefully and remember that you are responsible for these actions. So, be sure that you have both necessary equipment and skills. If not, we suggest that you should address to a qualified mechanic so as to implement these operations. We also recommend that you recycle your used oil by taking it to an oil change center or a waste recycling facility. Any type of oil can be reused: car oil, motorbike oil, truck oil, tractor oil, boat oil and others. In recycling, do not mix different products such as brake fluid, coolant and engine oil. Each fluid has to be recycled separately. Even small quantities of coolant or brake fluid in used engine oil could disrupt or halt the recycling process.
