Oil Change FAQs
How often should I change my oil?
Most modern vehicles with full-synthetic oil can go 5,000–7,500 miles between changes. Older vehicles or those using conventional oil typically need a change every 3,000–5,000 miles. Check your owner's manual or ask us — we'll tell you what's right for your specific vehicle.
How long does an oil change take at Benchmark?
Most oil changes are completed in 30 minutes or less. We'll let you know if we spot anything during the inspection that needs attention.
Do you offer a Saturday oil change special?
Yes — every Saturday we offer a discounted full-synthetic oil change. It's available only on Saturdays and slots fill up, so we recommend booking online in advance.
What oil brands do you use?
We stock Mobil 1 Full Synthetic, Castrol GTX, and other quality conventional and synthetic blend oils. We'll match the oil specification your vehicle requires.
