How to Preserve the Reliability of Your BMW 3 Series
The 3 Series is one of BMW’s most popular car models. This small luxury sedan’s sporty driving dynamics and quality interior help make it an appealing choice. While the 3 Series can last for upwards of 250,000 miles with no catastrophic mechanical issues, owners must have it serviced at the recommended intervals. Here are a few important tips to keep your BMW 3 Series performing at its best.
Always Use High-Quality Motor Oil
To no surprise, mechanics stress the importance of getting regular oil changes. This is one of the biggest keys to long-term durability. If you neglect having the oil changed on time, expect the engine to experience accelerated wear and tear.
It’s just as critical to choose the correct type of motor oil. If your 3 Series was built in the past 20 years, experts advise the use of fully synthetic BMW LongLife-01 engine oil. Not only is this oil formulated to provide enhanced protection, but it also promotes better fuel efficiency.
Invest in Genuine OEM Parts
If you own a 3 Series, don’t be a cheapskate when it comes time to replace components. While aftermarket parts from China are far less expensive, they may cause you trouble in the long run. There’s a good chance your car’s reliability will be severely compromised.
The best approach is to invest in genuine BMW parts. They are engineered to fit precisely and last longer. In the event that you decide to sell or trade in your 3 Series, the installation of OEM parts will boost the car’s value.
Replace the Spark Plugs
Spark plugs have a direct impact on engine performance. When they begin to wear out, your vehicle’s drivability will take a big hit. Some of the tell-tale symptoms include rough idling, sluggish acceleration, and difficult starting. Driving with bad spark plugs can also cause other costly components to fail, including the catalytic converter.
Most BMW manuals suggest replacing the spark plugs every 45,000 to 60,000 miles. However, this interval can vary from one model year to the next. Ideally, you should have the entire ignition system periodically inspected by a certified automotive mechanic.
Shy Away from Aftermarket Modifications
At some point, you could be be tempted to make modifications to your vehicle. Unfortunately, this is often a recipe for disaster. While it’s okay to install a different set of wheels, think twice before attempting to modify the car’s powertrain or suspension. For instance, some 3 Series owners in Asheville have opted to install a bigger turbocharger. The extra load subjects the engine to significantly greater stress, thus shortening its life.
If you’re a driving enthusiast who desires peak performance, purchase a 3 Series model that already comes equipped with performance upgrades from the factory. BMW’s available M Sport package includes a lowered performance suspension and beefier brakes.
Don’t Forget About the Transmission
Like the engine, the transmission needs to be properly maintained. It’s critical to have the transmission fluid changed at the recommended interval. Fresh fluid will help keep friction to a minimum, which ultimately enhances the gearbox’s durability.
When it’s time to have the transmission fluid changed, your mechanic will also install a new transmission filter. Most filters begin to become dirty after around 50,000 miles.
