Optimal Engine Rebuilding

How Long Should an Engine Last?

How long should an engine last? This question put up in thousands of people’s minds when they decide to purchase a motor from the market. And it must be because it is a costly product and you are investing your valuable money to earn and get its benefit for a long time as much as possible.

If you too are one in those thousand persons who are confused about this topic. So don’t worry about that as always AutoTechio is here to solve this problem. In this article, we will tell how long can it last either it is the rebuilt, new (crate), used or remanufactured engine.

Engine Lifespan

Long-time ago if we talk about 1916, at this time the engine ability was only 100 miles and after hundred years 10,000. For today’s generation cars Scholars say that nowadays the engine lifespan in a car has an average life of 100,000 miles. If you calculate it into kilometres its value will change to 160,000 km. But it is not the actual value of individual this is average and you better know that mean.

This can run up to more than this given numerical value. But it is not good to say, it will give you service for the lifetime. Because you know that very well nothing is permanent on this earth, and about other planets, sorry, we don’t know.

Yes, you can run an engine of your car more than this value. But how? Do you know anything about that? If you answered yes, congratulations, very good. And if you answered No, then ok no problem we will tell you.

As you know its average lifespan is one lakh miles but most of the engines stop working at only forty to fifty thousand and some continuously work up to 150000 miles and above. That all depends on you, its all depend on the maintenance of the engine.

How Long Do Rebuilt Engines Last?

When a car engine fails, it may be due to a single part becoming dysfunctional or broken. Engines are such delicate machines, after all, that every single part is crucial to its operation. When one part fails, the whole machine might fail.

When engines are rebuilt, a mechanic will deconstruct the engine for the sake of replacing any worn, broken, or old parts and replacing them with newer, superior ones.  While some car experts do not recommend that this be done unless the engine is almost new and only needs a few simple parts replaced, it is actually possible for an engine to be properly rebuilt. In fact, many experienced mechanics do this quite often.

A few factors determine if a rebuilt engine will be safe for driving:

  • The person who rebuilds the engine must have hands-on experience with fixing and building car engines.
  • The new or replaced engine parts must be compatible with the existing engine.
  • The engine as it is must be in poor condition or be missing several vital parts.
  • The engine must be completely compatible with the vehicle itself. In other words, you cannot install an engine built for a sports car into a car that is not built to be driven like a sports car.

How can you extend your car’s lifespan?

Want to improve your car’s lifespan and enjoy more functionality for your vehicle?

Here are a few tips to do just that:

  • Develop and adhere to a service schedule. When it comes to your car’s lifespan, an ounce of prevention is worth a pound of cure. While nobody likes spending time at an auto repair shop, arranging to be there on a scheduled and pre-set basis is the best way to avoid surprise visits. In addition to keeping you away from major repairs, regular maintenance also boosts your car’s resale value and extends its engine life.
  • Fix small problems quickly. Instead of driving around for a few thousand miles with your “check engine” light on, fix small engine issues promptly. Even tiny engine problems can become major ones if you don’t address them in a timely fashion. With this in mind, contact your mechanic as soon as you notice a funny noise, strange light, or odd symptom during your driving experience.
  • Clean your engine annually. You should clean your car’s engine at least once a year. Because dirt and grime can cause your engine to run hot, this layer of yuck puts extra strain on your car’s system and can contribute to things like overheating and a shorter-than-average engine lifespan. Adding a fuel injector cleaner is a great way to beat dirt and grime buildup.
  • Let your engine warm up. If you live in a cold climate, allow plenty of time for your engine to warm up before you drive off. Cold weather is hard on your car’s engine and can contribute to a lower-than-normal battery charge. Because of this, your car needs more energy to start the engine. Additionally, cold weather makes your car’s engine oil thick and dense, and the car needs to warm up to move it throughout pieces effectively.

How Long Do Important Car Parts Last?

Hiring a mechanic who will choose the right parts is very important. When the best parts are used, they will last longer and save you a lot of money on replacement parts and on other car problems. First, you need to know how long important car parts are supposed to last so you have a frame of reference.

Here’s what you need to know about the average life span of some of the most important parts in your car:


There is no other part in your car that is more important than the engine. Many factors influence its life span, so it’s hard to put a concrete number of miles or years on how long it will last. Typically, engines last around 150,000 miles on the low end and up to 350,000 on the high end.

How long your engine lasts depends in large part on how well it is maintained. Your engine needs fresh fluids, good exhaust and clean filters to work well. If any of these things are neglected, your engine will have to work harder, and its life span will be shortened.

The life span of your engine will also depend on how much abuse it takes. If you two heavy loads, regularly drive at top speeds, brake too quickly, rev the engine too much, or accelerate too quickly too often, you will shorten the life span of your engine.

Finally, how well the engine is made will influence how long it lasts. Generally speaking, engines made of iron are more durable than those made of aluminum. However, iron and steel are also heavier materials than aluminum, which will reduce the fuel efficiency. You should look for a balance of materials that will make the engine durable while also protecting your fuel efficiency.

Timing Belt

The timing belt is an important part of the engine. It ensures that the camshaft and crankshaft rotate in the right timing to move the pistons and valves in sync. If the timing belt fails, these parts could fire into each other, causing the engine to seize and requiring that you replace the whole engine.

The timing belt breaks down over time as the rubber decomposes. You can’t do anything to prevent this from happening. However, you can save yourself some money by replacing the timing belt on the recommended schedule. If you wait until the timing belt breaks, you will have to pay more. The engine may also become damaged, and that will cost you even more.


The starter is responsible for helping the engine start up when you turn over the ignition. How long a starter lasts varies wildly. However, a starter should last as long as the car itself if you maintain it well.

To prolong the life of the starter, you should keep your car tuned up. If the spark plugs fail, you will have to crank your car more before it will start. This will wear down the starter faster. However, if the spark plugs are healthy and the engine is healthy, your car should start right up and your starter should last a long time.


The alternator recharges the battery using power from your car’s engine. When it fails, you’ll hear a clicking when you turn the ignition rather than the roar of the engine. At first, you may think that your battery has died. However, charging your battery won’t let you start up the car.

An alternator can last between 40,000 miles and 100,000 miles, but the life span depends upon how many electrical components are in your car and how hard you run the car. It’s best to have the health of your alternator measured when you bring your car in for maintenance. You can then replace it before it breaks down, leaving you stranded on the side of the road.

Brake Pads

Brake pads are an important car component. Healthy brake pads ensure that you can stop quickly in an emergency. Without healthy brake pads, you increase your risk of getting into an accident. Thinning brake pads also put your brake rotors and other wheel components in jeopardy. It’s better to replace your brake pads on time than to have to replace these other parts, which will cost you much more money.

Typically, brake pads last between 30,000 miles and 70,000 miles. There is great variability in the life span based on a number of factors.

If you brake hard and quickly too often, you will wear your brake pads down more quickly. If you drive in extreme climates such as in very hot temperatures or on muddy or rocky terrain, your will wear your brake pads down more quickly.

The quality of the brake pads also has a big influence on their life span. Of course, higher-quality brake pads will last much longer than inexpensive, low-quality brake pads.
