Accordingly, can you switch back to regular oil after using synthetic?
Synthetic Motor Oil Myths
However, synthetic oil would not cause the leak. You can't switch back to conventional oil: Once you switch to synthetic, you are not bound to it forever. You can switch back to conventional oil if you choose to do so and your vehicle manufacturer doesn't recommend otherwise.
One may also ask, do you have to use synthetic oil every time? Though synthetics generally hold up better for more miles, regular oil changes remain important, and you shouldn't wait beyond the time interval recommended by the manufacturer—typically every six months or a year. Using synthetic in these situations will prolong your oil life and require fewer changes.
One may also ask, what happens if I put regular oil instead of synthetic?
If you use conventional oil in a vehicle that requires synthetic oil, you will void the vehicles warranty. Some vehicles require synthetic only because conventional oil does not come in the required weight. The thicker viscosity of conventional oil will not flow properly and cause the engine to wear out faster.
Will conventional oil hurt my car?
Switching from synthetic oil to conventional (and back again) won't cause any harm to your engine. Synthetic, synthetic blend and conventional oils are all compatible. However, if you ever need to top off your oil, we recommend using the same type of oil to get the best protection from the oil you've chosen.
