Express Oil Change Tops Quick Lube Segment of JD Power Customer Satisfaction Index

For the fourth consecutive year, Express Oil Change and Tire Engineers was top-ranked company in the quick oil change segment of JD Power’s U.S. Aftermarket Service Index Study, which was released on April 28.

Express Oil Change earned a score of 854 in the index, and was followed by Take 5 in second at 833, and Jiffy Lube and Valvoline Instant Oil Change tying for third at 823.

Now in its seventh year, the study measures customer satisfaction with aftermarket service facilities, divided into three segments: full-service maintenance and repair, quick oil change, and tire replacement. Scores are based on seven factors related to the vehicle owner service experience. The 2026 study’s results are based on responses from 10,572 vehicle owners, who were surveyed online from January to March.

Of the three segments tracked, quick lube was the only one to see an overall increase in customer satisfaction, with a 4-point increase on a 1,000-point scale. Full-service maintenance and repair (minus-7) and tire replacement (minus-3) both saw declines.

“Affordability is playing an increasingly important role in the aftermarket service experience, but delivering on the fundamentals remains critical,” Lisa Nguyen, manager of OEM Solutions at JD Power, said in a news release. “Index data shows that aftermarket providers are largely executing where it matters most, with the majority of impactful key performance indicators (KPIs) completed more than 70% of the time and the top two—the service advisor being completely focused on customer needs and providing helpful guidance—exceeding 90% completion rates across segments.

Still, Nguyen added, the survey revealed areas for improvement, including facility cleanliness, guest comfort, and consistency in customer engagement, from immediate greetings to post-service follow-up.
