The best thing to use for a squeaky garage door is a proper garage door lubricant, not a general household oil, and a systematic approach to application and hardware replacement. For immediate quieting, purchase a dedicated garage door lubricant spray that is silicone-based or white lithium grease-based. Products labeled garage door lube from WD-40 Specialist, Blaster, or 3-IN-ONE are formulated to penetrate bearings, stay in place, resist temperature extremes, and not attract excessive dust. Silicone spray is best for rollers, hinges, and bearing plates because it leaves a clean, dryish film. White lithium grease is best for heavy-load areas like torsion springs and metal rollers. Beyond just spraying, the best long-term fix for a chronically squeaky door is to upgrade components. Replace old metal rollers with premium nylon rollers that have sealed ball bearings, which can cut noise by more than half. Tighten all track bolts and hinge screws to eliminate rattles. Clean the tracks with a damp cloth to remove grit. If the squeak persists, the best thing to do is to have a professional check spring tension and door balance, because an unbalanced door will strain and squeak no matter how much lube you use. Avoid standard WD-40.
