Why a Crankcase Filter for My 6.7 Cummins Makes Sense

As a proud owner of a 6.7 Cummins engine, I’ve always been on the lookout for ways to enhance its performance and longevity. One of the best upgrades I decided to invest in was a crankcase filter. Initially, I wasn’t entirely convinced about its benefits, but after doing some research and eventually installing one, I noticed several significant advantages that made a real difference in my engine’s health.

First and foremost, the crankcase filter helps to trap harmful contaminants that can accumulate in the engine oil. This means that my engine is not only running cleaner but also more efficiently. By filtering out dirt, moisture, and other particulates, I’ve found that my oil stays cleaner for longer, which in turn extends the intervals between oil changes. This has not only saved me time but has also reduced my overall maintenance costs.

Additionally, I appreciate how the crankcase filter contributes to reducing blow-by gases. These gases can lead to increased oil consumption and, over time, can negatively affect the engine’s performance. Since I installed the filter, I’ve noticed a decrease in oil consumption, which gives me peace of mind knowing that my engine is operating optimally
