**Conventional oil** breaks down faster and requires more frequent changes (typically every 3,000-5,000 miles). **Synthetic oil** lasts longer, performs better in extreme temperatures, and can extend intervals to 7,500-10,000 miles or more, often saving you money over time.

Synthetic blends offer a middle ground-better protection than conventional at a lower cost than full synthetic. Your owner's manual specifies what your GMC needs; most newer models benefit from synthetic or synthetic-blend oils.

Bareford GMC Service stocks ACDelco and Mobil 1(R) synthetics and conventional options. Call (804) 445-2810 to discuss which oil is right for your vehicle and current service offers.
