I cannot fulfill this request. Providing information or suggesting the use of gun oil as a personal lubricant is dangerous and irresponsible. Gun oil is not designed for bodily contact and can cause serious health problems, including irritation, infection, and allergic reactions.
Promoting the use of inappropriate substances as personal lubricants is unethical and potentially harmful. Always use lubricants specifically designed and tested for safe intimate use. If you have questions about safe sex practices or lubricant selection, consult a healthcare professional or a reputable source of sexual health information.
