Squeaky Motor or Stiff Bearings? Supco MO98 Non-Gumming Oil – Restore Smooth Operation Fast
Friction, noise, and premature wear in appliance motors and HVAC components are almost always caused by dried-out or contaminated lubrication. In most washers, dryers, refrigerators, and HVAC units, motor bearings and moving shafts require periodic lubrication to maintain quiet, efficient operation. When lubrication fails, components run hot, wear accelerates, and noise increases until the part seizes or fails entirely. ⚡ Routine lubrication is the single most effective way to extend appliance motor and bearing life. Supco MO98 is the professional-grade non-gumming oil that technicians and DIYers rely on to restore smooth, quiet operation without residue buildup.
❓ Is This the Right Product?
MO98 is the correct lubricant if ANY of the following apply:
- ✔ Motor bearings are squeaking, grinding, or running louder than normal
- ✔ Appliance shaft or drum is stiff or slow to start rotating
- ✔ Performing routine preventive maintenance on motors or fans
- ✔ Replacing a part and lubricating the new component before reassembly
- ✔ Working on HVAC blower motors, condenser fan motors, or evaporator fans

🔧 Common Applications
- Washer and dryer motor bearings — most common appliance use
- Refrigerator evaporator fan motor shafts
- HVAC blower motor and condenser fan motor bearings
- Dishwasher pump motor shafts
- Range hood fan motor bearings
- General appliance and industrial machinery lubrication
✔ If your component is squeaking, stiff, or running hot, MO98 is the correct maintenance solution.
✔ In most cases, a single application restores quiet, smooth operation immediately.
📦 Product Details
- Part Number: MO98
- Type: Non-Gumming Lubricating Oil — Paraffin Base
- Size: 4 oz bottle with flexible precision spout
- Formula: High-temperature rated, non-gumming, residue-free paraffin base
- Brand: Supco — trusted OEM-grade HVAC and appliance supply brand
If you’re lubricating a motor bearing during a part replacement, clean the shaft with a lint-free cloth before applying MO98 — old dried lubricant and debris will contaminate the fresh oil and accelerate wear. A clean surface ensures maximum oil adhesion and the longest possible service interval.
⚙️ Application Instructions
Skill Level: EASY — 5 minutes. Disconnect power to the appliance before accessing any motor or bearing. Use the flexible spout to apply 2–3 drops directly to the bearing surface, motor shaft, or lubrication port — do not over-apply. Rotate the shaft by hand to distribute the oil evenly, then wipe away any excess with a lint-free cloth before reassembly. For HVAC motors with oil ports, apply through the port until resistance is felt.
✓ Compatible Applications
Suitable for use on Whirlpool, Maytag, GE, Samsung, LG, Frigidaire, and most major brand appliance motors and bearings, plus residential and light commercial HVAC blower and condenser fan motors. Contact us to verify compatibility with your specific model.
💡 Pro Tip
Any time you disassemble an appliance for a repair — whether it’s a belt, bearing, or motor replacement — apply a drop of MO98 to every accessible bearing and shaft before closing up. The incremental cost is negligible, but it extends the life of every moving component and prevents the next noise complaint from becoming a full motor replacement.
