The 10,000-Mile Myth: Where Did It Come From?
It wasn’t always like this. Go back a couple of decades, and you'd never hear a manufacturer telling customers they could wait this long between oil changes. So why the shift?
Jeremy Bucy pointed out that this trend really took off in the early 2000s when manufacturers moved from scheduled maintenance intervals to condition-based maintenance systems—essentially letting dash indicators dictate service needs. But here’s the issue: those so-called “smart” indicators don’t actually analyze oil quality. They simply track time and mileage, which can lead to dangerously long gaps between service visits.
And then there’s the marketing angle. Manufacturers figured out that if they could advertise “low maintenance” vehicles, they could sell more cars. What they didn’t tell consumers is that following these extended intervals can lead to costly engine repairs down the road.
What Happens When Customers Follow the 10,000-Mile Rule?
Both Mitch and Jeremy have seen firsthand what happens when customers wait too long to change their oil. Here are just a few of the horror stories:
Example 1: The 2014 Chevy Equinox Timing Disaster
Mitch shared a case where a customer religiously followed their dealer’s recommended 7,500-mile interval—only to end up needing a full timing system replacement due to sludge buildup. The variable valve timing system was gunked up beyond repair, costing the customer thousands.
Example 2: Honda CR-V Timing Chain Failure
Jeremy had a loyal customer who ignored his 5,000-mile synthetic oil recommendation and instead followed the 10% oil life indicator in their Honda CR-V. At 85,000 miles, their timing chain stretched, the tensioner failed, and the variable cam gear was toast—an $1,800 repair that could have been avoided.
Example 3: Subaru and Hyundai Oil Consumption Issues
Both Mitch and Jeremy have encountered multiple Subaru and Hyundai owners shocked to find their cars running on no oil by the time they came in for a change. Why? Because manufacturers like Subaru and Hyundai claim that burning one quart per 750-1,000 miles is "normal." Do the math on a 5-quart system, and that means an engine could be bone dry before the next scheduled oil change.
How Shops Can Educate and Build Trust with Customers
So how do we, as independent shops, combat these dealership narratives and educate customers on proper maintenance?
1. Start with the Right Questions
Jeremy has a simple rule of thumb: Ask customers how long they plan to keep their car.
If they trade in every three years, following the manufacturer’s extended intervals might not hurt them.
If they plan on driving it for 200,000+ miles, they need a different plan.
When customers hear it framed that way, they start to understand why proactive maintenance matters.
2. Use Digital Vehicle Inspections (DVI) to Show, Not Just Tell
Mitch’s shop records video and captures fluid samples during inspections. Showing customers sludged-up oil, worn-out belts, or dirty transmission fluid has a much bigger impact than simply telling them a service is due.
3. Give Customers a Custom Maintenance Plan
Mitch’s shop has developed a custom in-house maintenance guide based on real-world experience. Each new customer gets a copy, outlining realistic service intervals based on how they drive, not just manufacturer recommendations.
4. Build Relationships Through Service Advisor Training
Your service advisors are the front line of trust-building. How they explain maintenance needs can make or break customer relationships. As Brad shared on the podcast, advisors need to be able to deliver bad news in a way that reinforces trust—not fear.
5. Leverage Social Media to Educate at Scale
Customers may not listen the first time they hear something in your shop—but they will remember a short, clear social media post. Take videos of your techs explaining maintenance needs, show before-and-after service results, and consistently share these messages across Facebook, YouTube, and Instagram.
Final Thoughts: It’s All About Long-Term Customer Care
As independent shop owners, we have a huge opportunity to rebuild trust with customers by giving them the knowledge dealerships aren’t providing.
The key? Take the time to educate, show proof with DVIs, and provide a proactive maintenance roadmap. Your customers will thank you—not just now, but years down the road when their vehicle is still running strong while others are stuck with expensive repairs.
