  I can't imagine crawling under there every two months. Put a proper
lubricant on it for goodness sake!  WD40 is a Water Dispersant.
Fortieth attempt to formulate.  It's basically kerosene (which is why
it makes a good flame thrower or potato cannon fuel.)  It evaporates in
about 48 hours.
Use it to clean something but not as a lube. Waste of time and money.
