Cleans. Frees sticky mechanisms. Drives out moisture. Loosens rusted parts. And then gets sticky with age.

Spray it on a heavily rusted bolt and nut. Repeat the process every half hour. Eventually it will soak in and loosen that rusted nut.

A homeowner had sprayed WD-40 into every door latch. So much that a sticky film was binding every door latch. Each disassembled latch took hours in a paint stripper to remove that WD-40 film so that locks stopped binding.

Most 'guys' learn WD-40 myths. Only a minority learn reality. For example, if WD-40 really eliminated squeaks, then it never need be applied again.


That throttle cable must always be under spring tension so that the cable cannot disengage from that 'curved piece'. If a sticky part or missing spring results in loss of tension, then that throttle cable might disconnect. But again, pictures do not show how and where cable attaches.

Having sprayed WD-40 all over everything might have temporarily loosened the stickiness. Temporary cured a symptom.


What plthijinx has recommended should be practiced at least once by every driver. Learn how it is done where learning can be done safely. And before that 'knowledge' becomes necessary.

A moving car (with properly designed steering) does not need any power steering when the car is moving.

Also learn how often power brakes still work without an engine. And learn what eventually happens after hitting those brakes many times.

Power assist still works many times after an engine is off (if a check valve has not failed). But eventually its vacuum becomes 'used up'. Everyone should understand how to brake when power assist finally loses vacuum. A driver who has learned the 'feel' would not suffer a catastrophic surprise when brake assist fails unexpectedly.

All drivers should know how to power off an engine while the car is moving. Or how to shift to neutral. Few will need to learn that. But an informed driver knows how. Again, best place to learn is in a safe environment such as in a large, empty parking lot.
