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.
If you are looking at a technical archive titled "HTHS.rar," it likely contains: HTHS viscosity - BASINOL 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
