Reduces viscous drag, which significantly improves fuel economy and reduces emissions. However, if it's too low for the engine's design (typically below 2.6 mPa·s), it can lead to increased wear on camshafts and piston rings.

Provides a thicker, more stable oil film for better wear protection in high-load or high-performance engines. The trade-off is higher fuel consumption. Why This File Might Exist HTHS.rar

It is measured in mPa·s (millipascal-seconds) using specialized equipment like a rotary viscometer or capillary viscometer . The "Balance" Dilemma: Reduces viscous drag
