Question 1

How often should I change my oil in Crestwood, KY?

Accepted Answer

Most modern vehicles with full synthetic oil should have their oil changed every 5,000–7,500 miles, or every 6 months — whichever comes first. Older vehicles or those using conventional oil may need changes every 3,000–5,000 miles. Our Certified Care Plan tracks your vehicle's specific needs and reminds you when it's time.

Question 2

What is included in Certified Auto Service's oil change?

Accepted Answer

Our full synthetic oil change includes up to 5 quarts of full synthetic oil, a premium oil filter, a multi-point vehicle inspection with photos and video, and your personalized Certified Care Plan — all starting at $59.99. Additional quarts are available at a small extra charge.

Question 3

What's the difference between conventional and full synthetic oil?

Accepted Answer

Full synthetic oil is engineered to provide superior lubrication, better performance in extreme temperatures, and longer-lasting protection compared to conventional oil. For most modern vehicles, full synthetic is the recommended choice. We use full synthetic in all our standard oil changes.

Question 4

Does Certified Auto Service offer oil change discounts or rewards?

Accepted Answer

Yes — through our Certified Car Cash rewards program, every 6th oil change is completely free. You also earn 2–4% cash back on every service. New clients receive $10 in Car Cash on their first visit.

Question 5

How long does an oil change take at Certified Auto Service?

Accepted Answer

Most oil changes are completed within 30–45 minutes. We also offer a 24/7 key drop box if you'd prefer to leave your vehicle overnight, and a free Uber ride within 12 miles if you need to get somewhere while we work.
