How Often Should You Oil a Mechanical Clock?

Oiling is one of the most important maintenance tasks for ensuring the longevity and accuracy of a mechanical clock. Proper lubrication keeps pivots moving smoothly, reduces wear, and prevents costly repairs. But how often does a clock really need oil? Too many clock owners assume oiling is a frequent task, yet the correct interval is much longer — and applying oil too often can actually cause damage. This guide covers everything you need to know about when and how often to oil your mechanical timepiece.

Why Mechanical Clocks Require Oiling

As the gears and pivots inside a clock rotate, friction naturally builds. Oil acts as a protective barrier that prevents metal-on-metal wear. Without regular lubrication:

• Pivots grind into bushings

• Escapements wear prematurely

• Gear teeth accumulate abrasion

• Timekeeping becomes unstable

Over time, oil also dries out and attracts dust, forming a sticky residue that can stop a clock entirely.

Standard Oiling Interval for Mechanical Clocks

Most mechanical clocks should be oiled every 2–3 years, but this does not replace full cleaning.
A complete cleaning and overhaul is recommended every 5–10 years, depending on:

• Humidity

• Dust levels

• Clock type

• Frequency of operation

Grandfather clocks often need oiling more frequently than mantel or wall clocks due to larger, heavier movements.

Signs Your Clock Needs Oiling

Your clock may require lubrication if you notice:

• Dark or gummy oil around pivots

• Weaker pendulum swing

• Random stopping

• Chimes slowing or dragging

• Uneven beat

• Grinding or scraping noises

Dry pivot holes are the most common cause of wear in antique clocks.

Why You Should Avoid Over-Oiling

Too much oil causes:

• Dust accumulation

• Thick sludge formation

• Accelerated pivot wear

• Premature stopping

Only a single micro-drop is required per pivot point — never flood a pivot.

Can You Oil a Clock Yourself?

While some owners oil their clocks, improper lubrication can cause more harm than good. Avoid:

• Household oils

• WD-40

• Grease (except for mainsprings)

• Applying oil to dirty pivots

At Time and Seasons we use Horace Whitlock Clock Oil, which is specifically formulated for optimal performance. Whatever lubricant is used, always ensure that it is made for clocks. 

For best results, clocks should be professionally cleaned before oiling.
