Oil Separators/Oil Catch Cans for Mopar Vehicles
What Are Oil Separators for Mopar Vehicles and Why Do You Need One?
Oil separators, also known as oil catch cans, are designed to capture oil vapors from the crankcase ventilation system before they enter the intake. In Mopar vehicles, especially those equipped with the 3.6L Pentastar, HEMI V8 or supercharged engines, oil blow-by can lead to carbon buildup, reduced engine efficiency, and long-term performance issues.
Installing a Mopar oil catch can kit helps keep your intake system clean by trapping oil particles before they recirculate. This supports better combustion, improved performance consistency, and long-term engine protection, especially in performance-driven or heavy-use vehicles.
Mopar-specific kits are engineered to match your vehicle’s year, model, and engine type, ensuring proper fitment and optimal function. When choosing the right oil separator, consider:
- Engine type (3.6L, 5.7L HEMI, 6.4L, supercharged 6.2L, etc.)
- Model (Challenger, Charger, RAM, Jeep, etc.)
- Model year

Frequently Asked Questions
Yes. Both Hellcat and N/A HEMI engines are prone to oil blow-by, which can lead to carbon buildup and reduced performance. An oil separator (catch can) helps prevent these issues and supports long-term engine health.
Oil separators capture oil vapors and contaminants before they enter the intake system. This prevents intake valve carbon buildup, reduces the risk of pre-ignition, and helps maintain fuel efficiency and engine power.
Most high-quality Mopar oil separators are designed to withstand demanding conditions, including track use. Always check that your chosen kit is securely mounted and built for high-performance applications.
