One of the advantages of using synthetic motor oils or any synthetic fluids in your vehicle is the fact that they do provide you with longer mileage intervals between changes. Many new vehicles come from the factory with synthetic fluids already in them and the manufacturers’ recommend that you replace these fluids with the same type of fluid. Synthetic fluids tend to lower internal temperatures due to their molecular structure, all molecules are the same size compared to conventional oils, the molecules are of different sizes. Imagine a bunch of marbles as your synthetic oil vs. marbles, golf balls and baseballs as your conventional oil.
