The engine has its own way of getting around the issue of a plugged filter, it is called a by-pass valve, which basically opens if the oil pressure gets to high, and allows the oil to by-pass the oil filter. This ensures that the oil gets the oil flow it needs, but now the oil is not getting filtered at all. While this prevents an engine oil starvation issue, you can see how it certainly would not be ideal.
To get the most out of this balance, being able to filter out small particles, while maintaining flow, we look to the filtration media. The synthetic media allows for this, by having smaller openings, but more of them. The synthetic nanofibers also allow oil to flow easier in cold temperatures, preventing engine wear during warm-up periods. The AMSOIL Ea oil filters contain the synthetic nanofibers that allow for the best flow, best filtration, and have much greater capacity, allowing for extended oil drains.
