Oil drain plug thread stripping

Tags: #engine-oil · #drain-plug · #maintenance-interval

Changing engine oil very frequently (every 3,000–5,000 km or more often) can strip the drain-plug threads over time. One owner experienced the drain plug backing out along with its stripped threads after several years of overly frequent oil changes. Lesson: stick to the manufacturer-recommended interval (5,000–10,000 km) rather than changing more often than needed — over-changing doesn't just waste oil, it wears the plug/pan threads through repeated removal¹.
