Specialty Lubrication Guide: Choosing the Right XYC Grease for Automotive and Precision Parts
Lubrication is easy to get wrong. A grease that protects a steel bearing can swell a plastic boot, and one that runs well in a dashboard switch can leave haze on the windshield. This guide covers six XYC greases, each suited to a different job, so you can match the product to the part.
1. XYC TOPAS L 32 N: For Cold Starts and Plastic Gears in Electric Actuators
If a window lifter, sunroof, or seat motor slows down on winter mornings, the grease is often the problem. TOPAS L 32 N is a synthetic low-temperature grease for small plastic and steel gears inside electric actuators.
- Temperature range: Works down to -60 °C, with a continuous upper limit of +130 °C.
- Water and corrosion protection: Resists moisture washout, which helps keep steel tracks from rusting.
- Stability: Resists oxidative thickening and oil bleed under continuous high-frequency operation.
- Typical uses: Window lifters, power sunroof tracks, electric seat adjusters, headlight leveling motors, HVAC flaps, micro-motors, small cooling pumps, Bowden cables, and door locks.
- Plastic compatibility: Suited to plastic-on-plastic and plastic-on-steel gear pairs, including POM, PA, and PBT.
- OEM references listed: VW TL 778 A; Mercedes-Benz DBL 6827.40 and DBL 6827.41.

Best for: Cabin actuators that need to run reliably from deep winter cold to hot summer cabins.
2. XYC RM 47-102: The Anti-Fogging Silicone Grease for HVAC and Door Seals
Greasy haze on a windshield is a common complaint. Some lubricants release volatile compounds in hot cabins, and those compounds settle on glass and trim. RM 47-102 is a low-emission silicone grease designed to avoid that problem.
- Temperature range: -40 °C to +180 °C.
- Material compatibility: Neutral with thermosetting plastics, thermoplastics, and synthetic rubbers. It is designed to avoid swelling, shrinkage, and stress cracking.
- Low emissions: Formulated to minimize outgassing, which supports cabin air-quality requirements and reduces fogging.
- Typical uses: HVAC valves and flaps, cabin airflow louvers, gear shift gates and linkages, and door seals, weatherstrips, and EPDM O-rings.

Best for: Any interior part where you need smooth motion and no fogging or material damage.
3. XYC RA 44-702: A Damping Grease for Premium Touch and Quiet Controls
Plastic-on-plastic parts can click, rattle, or feel cheap. RA 44-702 is a synthetic PAO damping grease that adds resistance and softens these interfaces, so a control feels deliberate instead of loose.
- Temperature range: -50 °C to +130 °C, with short-term peaks to +150 °C.
- Material compatibility: Works with ABS, PC, POM, and PBT blends.
- Low oil separation and evaporation: The base oil stays in the thickener, which helps prevent creep onto fabrics, electrical contacts, and glass.
- Typical uses: Rotary dials, climate knobs, volume wheels, console compartments, grab handles, side-mirror tilt gears, glovebox latches, and sliding armrests.
- Beyond cars: Also used in audio faders, camera focus rings, and rotary potentiometers.

- Beyond cars: Also used in audio faders, camera focus rings, and rotary potentiometers.
Best for: Parts where the feel of the movement matters as much as the movement itself.
4. XYC M 2 JB: Long-Life Grease for High-Speed Bearings
Spindles and high-RPM bearings generate heat, and heat breaks grease down. M 2 JB uses a low-viscosity ester base to reduce internal friction and support long relubrication intervals.
- Low heat generation: Reduces localized overheating and bearing fatigue.
- Oxidation stability: Resists hardening over long operating periods.
- Rust protection: Helps block moisture and acidic vapors from steel rolling tracks.
- Cold-start behavior: Supports quick startup and low drag torque at low temperatures.
- Typical uses: CNC milling spindles, machine tools, textile machinery, sub-fractional horsepower actuators, instrument bearings, and outdoor or cold-environment machinery.

Best for: Precision rotating equipment where heat and long service life are the main concerns.
5. XYC LP 47-20002 KR: Lithium Complex Grease for Steering and Chassis
Steering and suspension parts take heavy loads and constant road vibration. LP 47-20002 KR is a synthetic lithium complex grease built for these conditions, with a high base-oil viscosity that forms a strong film between metal surfaces.
- Noise control: The thick oil film reduces clicking, ticking, and feedback inside steering and linkage parts.
- Boot compatibility: Designed to be neutral with TPE, TPU, and CR boots and bellows.
- Smooth breakaway torque: Helps prevent stick-slip, which can feel jerky under changing temperatures.
- Typical uses: Steering gearboxes, electric power steering (EPS) racks, steering columns, ball joints, tie rod ends, control arm bushings, and stabilizer bars, including on new energy vehicles.

Best for: Load-bearing steering and suspension parts that need quiet, predictable motion.
6. XYC LG 88 S: PAO-Ester Grease for Switches and Plastic Sliding Parts
Interior switches should feel crisp and consistent in every season. LG 88 S is a synthetic PAO-ester grease designed for switch blocks, stalks, and rotary dials, with a smooth, slightly dampened feel.
- Plastic compatibility: Neutral with ABS, PC, POM, PBT, and PMMA, with low risk of stress cracking or softening.
- Cold performance: Keeps switches from feeling stiff or hard to press in sub-zero weather.
- Low evaporation and creep: Helps prevent drying, outgassing onto windows, and migration to electrical contacts.
- Tactile tuning: Reduces micro-vibration and plastic clicks during hand operation.
- Typical uses: Turn signal stalks, hazard buttons, climate and volume knobs, side-mirror gears, glovebox latches, sliding overhead consoles, and small appliance dials.

Final Tip
Before you specify a grease, ask our technicians, confirm the operating temperature and material compatibility for your part, and test the lubricant on a sample. The right grease should protect the part, the material around it, and the way the user experiences it.
Frequently Asked Questions
1. Can I use one grease for every part in my car?
No. Each product in this guide targets a different job. TOPAS L 32 N suits electric actuator gears, RM 47-102 suits HVAC flaps and door seals, RA 44-702 suits damped controls, LP 47-20002 KR suits steering and suspension, and LG 88 S suits switches and plastic sliding parts. M 2 JB is for high-speed bearings outside the cabin, such as in machine tools.
2. Which XYC grease works best in cold weather?
TOPAS L 32 N is rated down to -60 °C, the lowest of the six products. RA 44-702 is rated to -50 °C, and RM 47-102 to -40 °C. For cold-weather actuators, start with TOPAS L 32 N. Always check the data sheet for your exact conditions.
3. Will these greases damage plastic parts?
The products are formulated to be neutral with common plastics and rubbers, such as POM, PA, PBT, ABS, PC, and TPE. This lowers the risk of swelling, cracking, or softening. Test a small sample on your actual materials before full use, especially with new or unusual plastics.
4. What does "anti-fogging" mean for RM 47-102?
Some lubricants release vapors in hot cabins, and those vapors can leave a greasy film on windshields and trim. RM 47-102 is designed to produce low emissions, which reduces this fogging risk.
5. Why are OEM specifications listed for some products?
TOPAS L 32 N is listed against VW TL 778 A and Mercedes-Benz DBL 6827.40 and DBL 6827.41. If your work must meet a specific manufacturer standard, confirm the product's approval status with the supplier and the official data sheet.
6. Can these greases be used outside automotive applications?
Yes. RA 44-702 is also used in audio faders and camera focus rings, and M 2 JB is used in CNC spindles, textile machines, and instrument bearings. Confirm the operating temperature, load, and material compatibility for your equipment first.
7. How do I choose between LG 88 S and RA 44-702?
Both are for plastic interfaces, but they serve different goals. LG 88 S suits switches and small dials where a smooth, slightly dampened feel and cold-weather performance matter. RA 44-702 suits larger controls and handles where stronger damping and a premium touch feel are the goal.
8. How often should these greases be reapplied?
The source material does not give relubrication intervals for most products. M 2 JB is described as suited to long relubrication intervals. For the others, follow the equipment manufacturer's maintenance schedule and the product data sheet.
