Although you'll find little argument about the advantages of synthetic oil over non-synthetic oil, using synthetic oil for engine break-in is still a point of contention. The reality is that many car manufacturers not only allow using synthetic oil during engine break-in, they actually ship the cars containing synthetic oil from the factory. If your automobile did not come factory-equipped with synthetic oil, and the manufacturer’s instructions do not expressly forbid changing to a synthetic during engine break-in, you can easily change to synthetic oil.
Review the owner’s manual for the manufacturer’s instructions for engine break-in to ensure they do not contain a prohibitive statement about using synthetic oil. Also check if the manufacturer offers a preference on brand for synthetic oil use.
Schedule an oil change with the dealership. It is best to schedule the oil change with the dealership where you purchased the car so it can have a record of the oil change in case a warranty repair issue comes up later.
Select a brand based on the manufacturer’s instructions or the advice of the mechanic.
Deliver your car to the dealership for the oil change. If possible, have the oil change performed before taking delivery of your automobile.
