It is important to change all your filters and fluid in the lifespan of your car. We all know too change the oil filter with every 5,000-mile oil change and the air filter at lease every 15,000 miles (depending on driving conditions). But what about a fuel filter? As a general shop rule that we have we would like to see a filter change between 60K & 80K miles, but you can do it earlier.  Same goes with trans fluid (auto and manual), and differential fluids (if you have one). Brake fluid and coolant should be done every 2 years. Take these small steps and you will have a car that lasts a lot longer with fewer problems.
