What is the Average Life of a Car Engine

As the vehicle ages, it becomes more and more likely that components within the engine will start to fail. While not always an immediate issue, when these failures do occur they can lead to a number of problems, including decreased fuel efficiency, shorter stints on the road, and potential safety issues. In this article, we’ll take a look at the average life expectancy of car engines and discuss some of the common issues that can arise.

What Causes Engines to Fail?

The average life of an engine is around 150,000 miles. This means that on average, engines will fail at around 130,000 miles. There are a few factors that can cause engines to fail prematurely. The most common culprits are age, mileage, and wear and tear.

Age is the biggest factor in engine failure. Engines get older over time and the metal parts start to wear down. This can cause engines to misfire or run too hot. Mileage is also a big factor in engine failure. The more miles an engine has been put on it, the more wear and tear it will experience. This can cause weakening of the parts or even complete failure. Finally, wear and tear is caused by things like driving habits, collisions, and temperature extremes. All of these factors can lead to premature engine failure.

How long do most engines last?

Most car engines last around the average of 8-10 years. However, there are many factors that can affect how long an engine will last such as its make and model, driving habits, and regular maintenance.

Engine Maintenance and Tune-ups

The life of a car engine can typically be estimated to be around 100,000 miles. At this point, the engine may start making strange sounds or developing leaks. It is important for drivers to schedule regular tune-ups and maintenance to keep their engines running smoothly.

What to do if your engine fails

If you’re like most drivers, you probably take your car for granted. You might not think twice about a routine oil change or check-up, but if your engine fails, you may not be as prepared. In fact, it’s not unusual for an engine to fail between 10,000 and 15,000 miles.

Here are some tips on what to do if your engine fails:

1. Get a tow truck. If your car is disabled and can’t be moved, get a tow truck to take it to a nearby mechanic. Many garages offer free or discounted rates for cars with failed engines.

2. Replace the engine. If your car is still drivable and the engine is at least 10 years old, it’s likely time to replace it. Check with your car’s manufacturer for replacement advice and pricing.

3. Fix the problem. If your car is still drivable but the engine is less than 10 years old, there’s a good chance you can fix the problem yourself without replacing the engine. 

Engine Replacement

The average life of a car engine is typically around 100,000 miles. This means that on average, a car engine will be replaced every 10 years.


It’s hard to guess how long an engine will last, as engines are designed to last a certain amount of time and then be replaced. However, the general lifespan for most car engines is around 150,000 miles. After that point, it’s usually recommended to have the engine replaced.
