In our years of serving the Kenai Peninsula we have serviced many diesel trucks. These services vary from oil changes to complete engine overhauls and everything in between. In the course of these services and repairs we have noticed an alarming trend involving the use of low quality fuel filters being installed on diesel trucks. Below are 3 ways to help you avoid catastrophic fuel system failure.
#1 Change Your Fuel Filter Every 15,000 Miles ( Or Once A Year )
The key to a healthy diesel engine is healthy fuel. There are many factors that play into keeping your fuel system running properly, but one of the most overlooked is how often a fuel filter should be changed. There are two main reasons to change your fuel filter. The first reason is obvious... it's not designed to last forever. Every filter gets clogged and deteriorates over time. The second reason, is that it gets full! If that last statement did not make sense to you, don't worry. We find that most people don't realize what the fuel filter on their diesel truck is actually doing.
There are two main objects that a diesel engine fuel filter is designed to filter. The first is the most obvious, Foreign Substances. This includes anything and everything that's in your fuel that shouldn't be there. The better the filtration level of your filter the less likely you are to have your truck's fuel system clogged with junk that shouldn't be there, but more on that later.
The second thing your fuel filter is filtering is Water! Diesel fuel is hygroscopic. Unfortunately water damages diesel engines.So in order to remove the water from the diesel, fuel filters are designed to separate the water from the fuel and then store said water in a Separator at the bottom of the filter. Then when that Separator is full your engines fuel system is susceptible to being exposed to water. This can quickly and permanently damage your engines fuel system. Meaning that the bigger the Separator the more effective the filter, which leads us to our next point...
#2 DO NOT USE A CHEAP FILTER
Rather than just telling you to use the biggest and best OEM filter for your truck, we figured it would be more effective to show you why using a cheap fuel filter could destroy your fuel system and in turn your engine! Below we are going to show you the difference between a “Cheap Generic” filter, a “Mid Level Generic” filter, and a “Top Level OEM” filter.
We are going to judge these filters based on 3 different factors that play into how effective a fuel filter operates.
