When it’s time for an oil change, it’s important to use the correct oil. You must use synthetic oil if your vehicle requires synthetic oil. Not doing so can have disastrous consequences in the near future. Sludge build up can occur, causing malfunctions to critical sensors dependent on oil pressure to work properly as well as several potentially costly repairs.
Service for engine failure or oil related failures, normally covered under warranty, can be denied by your dealer due to improper oil whether your vehicle is a lease or not. Synthetic oil may appear to be more expensive than standard oil but the cost is virtually the same, having to be changed approximately 6-7000 miles offers twice the oil life of standard oil that must be changed at approximately 3000 miles. So, remember to take care of your vehicle so it will take care of you Since the cost of using the improper oil can be potentially through the roof.
