Frequently Asked Questions

Quick answers to questions we hear most often from our customers.

Most modern vehicles require oil changes every 5,000 to 7,500 miles with synthetic oil, or 3,000 to 5,000 miles with conventional oil. Check your owner's manual for the manufacturer's recommendation. We also recommend oil changes at least annually even if you don't drive many miles, as oil degrades over time.
Watch for these warning signs: squealing or grinding noises when braking, a vibrating steering wheel, a "soft" or "spongy" brake pedal, taking longer to stop, or the brake warning light illuminating on your dashboard. If you notice any of these, schedule an inspection promptly.
Yes! We stand behind our workmanship with comprehensive warranty coverage. Most parts carry a 12-month or 12,000-mile warranty (whichever comes first), and our labor is guaranteed for the same period. If anything goes wrong due to our work, we'll make it right at no charge.
