How Long Will a Subaru Boxer Engine Last?

Subaru’s boxer engine is one of the brand’s most iconic features. It’s been around for decades and powers some of Subaru’s most popular models, like the Outback and Forester. So, how long does this engine last?

Generally speaking, a Subaru boxer engine will last between 150,000 and 200,000 miles. This is assuming that the engine has been properly maintained throughout its life. Of course, there are always exceptions to this rule and some engines may last longer or shorter depending on various factors.

One thing that can impact an engine’s longevity is how it’s used. For example, if you regularly drive in stop-and-go traffic or haul heavy loads, your engine will likely wear out sooner than someone who mostly drives on highways or lighter loads. Additionally, how you maintain your vehicle also plays a role.

Regular oil changes and tune-ups can help extend an engine’s life while neglecting these things can shorten it. So, if you’re wondering how long your Subaru boxer engine will last, the answer is anywhere from 150k to 200k miles – but it really depends on a number of factors specific to your car and driving habits. Just be sure to take good care of it and you should be able to enjoy many trouble-free miles!

Do Boxer Engines Have Problems?

Boxer engines have a few potential problems that owners should be aware of. First, the engine can develop oil leaks. These leaks can be caused by a variety of things, including age, wear and tear, and improper maintenance.

If not fixed, oil leaks can lead to engine damage. Second, the engine may develop cylinder head or valve problems. These issues are usually due to poor maintenance or overheating.

Overheating can cause the valves to warp or the cylinder head to crack. If not repaired, these problems can result in engine failure. Finally, boxer engines are susceptible to piston rings breaking or burning out.

This is often caused by driving too hard or using low-quality fuel.

What is the Most Reliable Subaru Engine?

If you’re looking for a reliable engine in a Subaru, you have a few different options. The most reliable engines are typically the ones that have been around the longest and have had the most time to prove themselves. In general, that means the horizontally opposed “boxer” engines like the ones in the Impreza and Crosstrek models.

These engines are known for their longevity and reliability. Another option is the turbocharged engine in the WRX and STI models. This engine has been used in Subaru’s performance cars for many years and has a reputation for being both powerful and reliable.

However, it should be noted that this engine does require more regular maintenance than some of the other options. Finally, there is also a new generation of turbocharged boxer engines that are being used in some of Subaru’s newer models like the Ascent SUV. These engines offer similar power and performance to the WRX/STI engine but with improved fuel economy and lower emissions.

So far, they seem to be living up to Subaru’s reputation for reliability.

Are Boxer Engines Less Reliable?

There is no definitive answer to this question as it largely depends on how well the engine is maintained and taken care of. However, in general, boxer engines are considered to be less reliable than other engine types due to their design. Boxer engines have horizontally opposed cylinders which can lead to increased vibration and wear over time.

Additionally, the pistons in a boxer engine are typically closer together than in other engine types, which can also contribute to increased wear and tear.
