In normal engine use regular petroleum based oil will break down over time. When the oil gets too hot it will reach a gas state making the oil break down and not be able to lubricate your motor. When this occurs the engine will get a burned up residue in it which is called burnt carbon or buildup. This is why it is important to change your oil every 3,000 to 5,000 miles and avoid this common problem. When using synthetic oil in your motor, it will not break down at the same engine operating temperature as petroleum oil since synthetic oil remains in a liquid form longer making it a better product for your motor. Because the synthetic oil can tolerate these temperatures without breaking down your oil changes can extend out to as much as 7,000 miles before having to change it.
You may get more mileage between oil changes by using synthetic oil but it is more expensive than petroleum oil so there is a trade off for using the synthetic product. If I am using petroleum oil can I switch to synthetic oil? Yes, but when you are ready to make the change from petroleum oil to synthetic oil you cannot just put in new synthetic oil with your old oil. First you must drain the old oil completely out and flush the system. Make sure you also change out your oil filter. Once you have flushed the system, add your synthetic oil and drive it for 2,000 to 3,000 miles then change your oil again to get out the rest of the old residue. Refill again with synthetic oil and you will be good to go for another 7,000 miles. It is best to have an experienced mechanic perform the oil change for you.
