SMART-O Plug vs Regular Oil Drain Plug - Vibration Test | Oil Drain Plug | Drain Plug | Sump Plug
SMART-O® plug was tested under adverse conditions - extreme vibrations up to 9G by Spectrum Technologies in Michigan. The result was that the regular plug vibrated loose after 5 minutes while SMART-O® plug stayed fixed in the oil pan and did not drain the oil.

The test proves that SMART-O® works and excels in sealing and anti-vibration (retention) performs it's intended function.
