Can I switch between synthetic and conventional oil?

Yes, it’s possible to switch between them, although it’s best to follow your vehicle’s manufacturer recommendations. If your car is older, consult a mechanic before making a switch.

Is synthetic oil worth the extra cost?

In most cases, yes—especially if you want longer intervals between changes and better protection. For frequent drivers or those in extreme climates, the investment often pays off.

How often should I change synthetic oil?

Many full synthetic oils are rated for up to 10,000 miles between changes, but always check your vehicle’s maintenance guide for specifics.
