• Silicone (siloxane) base oil – Provides excellent low-temperature properties, high thermal stability, and good oxidation resistance for long-term lubrication in automotive mechanisms.
• Lithium soap thickener, NLGI Grade 1 – Delivers a soft, pumpable grease body that can be applied by brush, grease gun, automatic feed, or centralized lubrication systems while remaining in place on parts.
• Excellent low-temperature performance to -50 °C – Maintains lubricity and low starting torque in cold-start conditions, supporting smooth operation of control cables, clutches, and wiper gears in winter climates.
• Wide service temperature range (-50 to 170 °C) – Provides a single grease solution that covers cold-soak through elevated operating temperatures in interior and under-hood locations.
• Good plastic and elastomer compatibility – Formulated to work with many plastics and elastomers, reducing risk of stress cracking, swelling, or softening in cable liners, plastic housings, and seals.
• Low friction in steel/plastic contacts – Designed to minimize friction and stick-slip in steel-against-plastic combinations, ideal for mixed-material mechanisms such as starter overrun clutches and wiper motor gear trains.
• Low evaporation at elevated temperature – Evaporation of about 1.8% at 150 °C helps the grease resist drying out and maintains a stable lubricating film in long-life automotive applications.
• Good corrosion resistance – SKF Emcor corrosion rating ≤ 1 indicates good protection of metal components against rust in the presence of moisture.
• Visually identifiable purple color – Distinct color makes it easy to confirm coverage on assembly lines and during service inspections.
• Suitable for centralized lubrication systems – Consistency and rheology allow use in centralized systems, enabling automated delivery where appropriate.

Cold-weather stiffening and high starting torque in mixed metal/plastic mechanisms such as starter motor overrun clutches, control cables, and wiper motor gears G-5042’s silicone base oil and excellent low-temperature properties keep friction low and motion smooth down to -50 °C, reducing effort, noise, and stick-slip during cold starts. Damage to plastics and elastomers caused by incompatible mineral or hydrocarbon greases - Because G-5042 is compatible with many plastics and elastomers, it reduces the risk of swelling, cracking, or softening in plastic housings, cable liners, and seals that are in continuous contact with the grease. Need for a single, plastic-safe automotive service grease that covers both interior and under-hood temperature extremes - The -50 to 170 °C service-temperature range allows engineers and maintenance teams to standardize on one silicone service grease across multiple mechanisms instead of juggling different products for cold and hot zones. Uncertain or inconsistent lubrication coverage in assembly and service operations - The distinctive purple color makes applied grease easy to see on parts, helping technicians verify coverage and thickness quickly and reducing the chance of missed lubrication points. Grease dry-out and loss of protection in long-life automotive mechanisms exposed to elevated temperatures - Low evaporation at 150 °C and good oxidation stability help G-5042 maintain a lubricating film over time, supporting longer service intervals and reducing noise or wear complaints in starter clutches, cables, and gear drives.
