1 Answers
The correct method for high-speed engine running-in of a car is as follows: Change the engine oil: After changing, drive several kilometers to allow the new oil to fully integrate with the engine. Shift gears: Start from 1st gear to 3rd gear, gradually increasing the RPM for each gear (do not stomp on the accelerator suddenly. First drive at around 3000 RPM for a short while, then increase to 4000, 5000 RPM. Adapt to three to four RPM levels per gear, finally maintaining about 4/5 of the tachometer's maximum RPM (generally above 5500 RPM for 3 minutes). Maintain each gear for a total of 5 minutes (do not exceed this duration too much). Change the engine oil: Remember to change the engine oil immediately after the high-speed running-in.
