Here's why:
* Engine mounts are designed to absorb vibrations: They are made of rubber or a similar material that is meant to flex and dampen vibrations from the engine. Filling them with oil would make them too stiff and unable to perform this function.
* Oil would leak: Oil would leak out of the engine mount over time, creating a mess and potentially damaging surrounding components.
* Oil can damage the engine mount: Oil can degrade the rubber material of the engine mount, making it brittle and prone to failure.
If you're experiencing problems with your engine mount, it's best to replace it with a new one.
