100% synthetic will not go bad by itself. What makes 100% synthetic oil bad is basic oil filtration. The oil filtration system on a car is not very efficient, therefore allows the oil to get dirty. Once the oil gets dirty, the oil does not fare as well. There are brands of 100% syn oil that only require a 1yr/25,000 mile change (with guarantees-- Google search 25,000 mile oil change). There are others (on store shelves) that require a 5000 mile change, but charge the same price as the 25,000 mile oil change. Make sure to look for 100% syn. There are syn oils out there that are actually a "synthetic blend", which means it's part syn, part conventional oil.

All right to go from full synthetic motor oil to synthetic blend motor oil?
I work for a lube distributor. It is fine to go from synthetic to synthetic blend. Here's the difference: No manufacturer will actually release how much synthetic is in their synthetic blend formula. It may actually be closer to a conventional oil than a synthetic oil. The benefit of synthetic is that it offers better protection for your vehicle/ machinery. The secret is that it only makes a true difference if you're one of those people who doesn't change your oil regularly. If you choose to go synthetic blend, make sure you keep up with how often you change your oil!
