Rethinking Oil Change Intervals: A Technician’s Perspective

With decades of hands-on experience servicing vehicles and diagnosing internal engine issues, we understand just how vital regular oil maintenance is to engine longevity. In recent years, the automotive industry has shifted toward newer methods of determining oil change intervals—often relying on algorithms, driving habits, and onboard monitoring systems. While these advancements are marketed as more efficient, our experience tells a different story.

We’ve observed a growing number of engine failures linked to extended oil change intervals recommended by these systems. Issues such as sludge buildup, timing chain failures, and major component breakdowns are becoming increasingly common—and often surface only after factory warranties have expired, leaving consumers with costly repairs.

From our professional standpoint, we strongly advise against exceeding the traditional "3 months or 3,000 miles" guideline, regardless of the type of engine oil used. Sticking to this tried-and-true rule remains one of the most effective ways to protect your engine and avoid preventable damage.
