Automotive engineers utilize PDMS-dimethyl fluids for:

Shock absorber oils: Temperature-stable damping (η change <5% from -30°C to 150°C)

Thread lubricants: Preventing galvanic corrosion in aluminum fasteners

Noise reduction: 3-8 dB NVH improvement in electric vehicle gearboxes

Emerging silicone-ionic liquid hybrids promise extended service life in EV battery cooling systems.
