When an engine has not been run for a long time, internal metal components such as the cylinder and piston rings may become dry or less mobile.
In such cases, spraying a small amount of lubricant through the spark plug hole can be an effective preparation before restarting the engine.
LS Bell Hammer Gold Spray is highly effective at reducing metal-to-metal wear and is suitable for this kind of application.
However, please observe the following precautions when using it:
When spraying through the spark plug hole, apply only a small amount (a 1–2 second spray is sufficient).
Excessive application may make it harder for the engine to start.
After spraying, before reinstalling the spark plug, crank the engine several times to expel any excess lubricant inside.
Once the engine starts, we recommend letting it idle for a while so that the engine oil can circulate normally.
If you are unsure about the procedure, we recommend consulting with a professional automotive service shop for added safety.
