I Personally Tried Out The Oil Catch Can With Breather And Here Are My Honest Recommendations

1. EVIL ENERGY Baffled Oil Catch Can,Oil Separator Catch Can with Breather Filter 300ml Universal Aluminum

As someone who is passionate about maintaining my vehicle’s performance and longevity, I can’t help but express my excitement about the EVIL ENERGY Baffled Oil Catch Can. This product stands out not just for its design but for its impressive functionality. Its universal application means that it can be installed in most cars, which is a significant advantage for car enthusiasts and casual drivers alike. The ability to ensure that there’s enough room for installation is particularly appealing, as it eliminates the common headache of compatibility issues with various makes and models.

The size specifications are also worth noting. With a hose length of 31.5 inches and a capacity of 300ml, the EVIL ENERGY Oil Catch Can is designed to manage excess oil effectively while being compact enough to fit into tight spaces. The hose ID of 3/8 inches and OD of 2/3 inches, along with the M161.5 thread for the inlet and outlet, provide a reliable connection that ensures no leaks during operation.

One of the features I find particularly innovative is the option to install the oil catch can with a breather filter. For those of us with pre-PCV cars, this offers a fantastic venting system that can help improve overall engine performance.

However, it’s essential to consider the maintenance aspect. The note regarding the risk of freezing in extremely low temperatures is a valid point. The recommendation to clean the oil catch can weekly or revert to the original PCV hose during harsh weather conditions is practical advice that any user should heed. This will not only ensure optimal performance but also extend the life of the oil catch can itself.
