Do I Need to Change My Air Filter?
The short answer is yes. Your air filter should be changed according to your owner's manual, however if you frequently drive in dusty areas such as construction sites or off-road trails, more frequent changes may be a good idea. Your air filter is designed to keep dirt and other foreign material out of your engine while also regulating the fuel and air mixture that creates the combustion to propel you along. When your air filter becomes too dirty, the proper amount of air is unable to reach your engine's combustion chamber resulting in power loss, poor fuel economy, and hesitation under acceleration.
I Always Drive Slowly and Avoid Potholes, Do I Need to Worry About an Alignment?
While the amount of time you drive between alignments can vary, it is always a good idea to have your alignment checked every time you replace your tires. Even gentle driving can, over time, affect your vehicle's alignment, and a misaligned suspension can lead to a host of other issues if left unchecked. Uneven tire wear, unpredictable handling, unstable braking, vibrations, and a harsh ride can all result from driving a vehicle that is out of alignment, and that is just the beginning. Extreme vibrations can cause problems with steering components, brake calipers, and wheel bearings, all of which are much more costly than simply having your vehicle aligned properly.
