A car part you probably never think about but should
We all know we have to change our oil and rotate our tires, but how often do you think about the fuel filter? I know I didn't until I learned a bit about it, especially for older cars.
The answer really depends on what you drive. If you've got a newer gas car, you might never have to worry about the fuel filter. A lot of those cars have something called a "lifetime" fuel filter built right into the gas tank. That sounds great, but "lifetime" usually just means the life of the fuel pump, not the car itself. For older cars, the filter is usually outside the gas tank and needs to be replaced every 20,000 to 40,000 miles or so.
Now, if you drive a diesel, that's a whole different story. Their filters have to be changed a lot more often, and some diesel engines even have two. The best place to check is always your owner's manual. But there are also some signs that your filter might be clogged, like if your car has trouble starting or the engine runs rough. I've heard a few stories of engines just stopping while a person is driving, and it all comes down to a clogged filter.
