Why I Chose Permatex Oil Pan Sealant
I wanted a reliable sealant that would prevent oil leaks, be easy to apply, and withstand engine heat. Permatex is a well-known brand in automotive sealants, and their oil pan sealant promised excellent adhesion and flexibility. This made it my top candidate.

Once cured, the seal felt durable and flexible. Over time, I noticed no leaks, even after multiple heat cycles and driving on rough roads. It held up well, giving me confidence in its quality.
What to Consider Before Buying
- Compatibility: Make sure the sealant is compatible with your vehicle’s materials—Permatex works well on metal surfaces.
- Surface Preparation: Proper cleaning and drying of the oil pan and mating surface are crucial for the best seal.
- Application Environment: Avoid applying in very cold or humid conditions to ensure proper curing.
