This rule of thumb was largely based on the technology of older engines and the type of oil available at the time. Today, engine manufacturing and oil chemistry have advanced significantly.
Oil Change Every 5000 Miles Necessary Today
Most modern vehicles are equipped with sophisticated engine management computers and are designed to run efficiently much longer between services. Ignoring the recommended oil change intervals is a primary cause of premature engine wear, leading to costly repairs down the line.
