Petro Oil, also known as Crude Above 250, is a hydrocarbon oil used widely as a fuel source in the automotive and aviation industries. It is also used as a lubricant and a chemical feedstock. Common types of rubber failures when exposed to Petro Oil include swelling, cracking, and hardening. These failures are caused by the oil’s ability to penetrate and degrade rubber’s molecular structure, leading to a breakdown of the material. Additionally, Petro Oil can cause rubber to become brittle and lose its elasticity over time.
