Let’s take a closer look at why it’s important to empty the gas tank, the problems that can arise from stale gas, and the benefits of regular maintenance.

The Importance Of Emptying The Gas Tank:

  • The fuel’s evaporating components can leave behind a sticky and varnish-like substance that clogs fuel lines and carburetors.
  • Stale gas can lead to engine misfires, decreased power, and even complete engine failure if not addressed promptly.
  • Ignoring the issue may result in costly repairs and the need to replace parts damaged by clogged fuel systems.

Benefits Of Regular Maintenance:

  • Emptying the gas tank regularly as part of routine maintenance extends the lifespan of your lawn mower.
  • Preventive measures like draining the gas tank help ensure your mower is always ready to go when you need it.
