Note when using vehicles with turbocharged engines

Turbo has 2 main parts: turbine and compressor. When operating, the turbine can rotate very high, up to 170,000 rpm. This makes the engine more powerful. Because it operates at high speed and in a high temperature environment, turbochargers need periodic maintenance to help the turbo operate most effectively.

In the article below, CarOn will share with you some experiences for Turbo maintenance.

Common errors in Turbo

The lifespan of the turbocharger is quite high. Under ideal working conditions, turbocharger life can be up to 200,000 – 300,000 km or more depending on operating conditions and maintenance. However, during the process there will also be times when failures occur. Here are some signs that the Turbo is in need of maintenance.

Loss of engine lubricating oil – a sign of turbocharger engine failure.

According to experts in the field of auto parts maintenance, traditional turbochargers are often lubricated and cooled thanks to the engine’s oil pump system. Therefore, this turbo engine often has errors such as oil loss during the oil change cycle and needs to be replenished. Therefore, loss of engine lubricating oil is a sign of damaged auto parts.


Because turbo engines have to work in very harsh conditions at high speeds, up to 100,000 rpm. Therefore, for vehicles using turbo engines to function well, the turbo system needs to be continuously lubricated. Car owners should also consult reputable garages for advice on how to best care for their car’s turbo engine.

Broken oil system

Traditional turbocharged engines are lubricated and cooled by an oil system from the engine. After many years of use, the turbo lubricating oil pipeline system or the gaskets/seals will leak, leading to lack of or no lubricating oil for the turbo. When you hear an explosion that is noisier than usual, the car owner should urgently bring the car to the garage for inspection as soon as possible.


Leaking or broken air compressor hose

To facilitate disassembly and maintenance, the turbocharger’s air compression piping system is often made of plastic and rubber. Some high-end cars can be made of alloy. The air compression pipe is connected from the turbocharger to the engine through a belt system or sealing gasket.

After many years of use, the material can degrade, and the gas pipe from the turbocharger to the combustion chamber can have leaking gaskets, causing compressed air leaks. Many cars have even been reported to have a leaking turbo air duct, causing the car to run very weakly and the driver can completely feel it.

Damaged or worn silver or balls

A sign of a damaged turbocharger or worn bearings or bearings is that the engine makes a buzzing sound when operating, especially when accelerating.

In addition to making noises as mentioned above, worn turbo bearings can also lead to faster engine oil loss, reducing turbo compression, reducing engine power. The driver may feel the vehicle is sluggish and weak, especially when accelerating.


Instructions on how to preserve Turbo engines

Step 1: Drain residue from the fuel tank using the tank drain plug.

Step 2: Drain all fuel from the tank and remove it from the machine.

Step 3: Use diesel or kerosene to rinse the barrel.

Step 4: Use kerosene or diesel to clean the fuel tank cap and filter screen.

Step 5: Remove the screws on the filter and pump. Then loosen the connections of the high pressure hose.

Step 6: Release air from the high pressure pipe.

– Note:

  • You must leave the throttle at the maximum level.
  • Avoid having the engine start interrupted. Venting must be done carefully.

Step 7: Let the engine rotate with the starter.

Step 8: Clean, check turbo engine nozzles and perform calibration.

Step 9: Restart and test.

Things to note when using a turbocharged vehicle

Whether a turbo is durable or not partly depends on how it is operated and maintained. Therefore, to prolong the life of the Turbo engine, users need to pay attention to the following things:

You should limit movement immediately after starting the car to avoid affecting the turbo.

Modern car engines today use electronic fuel injection systems, so there is no need to let the car run for too long before moving. However, if you use a turbocharged vehicle, many experts advise that you should still let the vehicle idle for a few minutes before rolling off the road.

car is hard to start caron

The reason is that the turbocharger uses the same lubricating oil as the engine. When the car has just started, the engine oil is still cold (thicker) so it circulates more slowly. And now the oil also needs time to pump up. Therefore, the engine and turbo lubrication effect is not good.

Do not turn off the engine immediately after stopping the vehicle

The reason is because turbocharger Use lubricating oil in conjunction with the engine. Therefore, when the car has just started, the engine oil is still cold so it circulates more slowly.

If the engine is suddenly turned off while the engine is still hot, the oil in the engine will not circulate but will only have local contact in some hot locations. This easily causes the oil to lose quality, the additives in the oil decompose faster, and the oil deteriorates faster. Therefore, when riding a turbo car, the driver should pay attention to slowing down a few kilometers before the destination. After stopping the car, let the car run for 2-3 minutes then turn off the engine.

Absolutely avoid driving at too low an engine rpm

Driving in high gear at slow speeds is one of the causes of damage to the turbocharger. This process puts the engine in low gear, creating the illusion of better fuel economy. However, for turbocharged engines, running at low rpm is not equivalent to fuel economy.


The reason is because the turbocharger uses exhaust gases to achieve high speeds, helping to increase the amount of air entering the engine. When the turbocharger does not reach a certain rpm threshold, it will cause the vehicle to not reach the optimal power threshold that the engine can produce.

For diesel engines, fuel is provided by stepping on the accelerator. When driving in high gear at low speeds, the user needs to step on the accelerator more to keep the engine running. This is the reason why the engine operates with excess fuel, lack of air in the combustion chamber and causes the fuel to not burn completely. Drivers should use a gear appropriate to the driving speed.

Use gasoline with the correct recommended octane rating

In the vehicle owner’s manual, the manufacturer often clearly recommends the type of gasoline with the appropriate octane number. Users should comply with this recommendation. Do not use gasoline with a lower octane rating. Because it can cause the car to detonate fuel at the wrong time, affecting the life of the engine and the turbocharger.


You should pay attention when the car turns to avoid the car slipping and losing control.

Vehicles using turbocharged engines often have lag because power increases as soon as the turbocharger starts working. This causes the vehicle to understeer or oversteer and cause skidding and loss of control. For vehicles using turbochargers, drivers should not step on the accelerator too close to the board when exiting a curve.


When the engine is not used for a long time, it is necessary to rotate the engine crankshaft to create even lubricating oil pressure throughout the engine parts. During engine inactivity, the lubricating oil will thicken and not provide adequate lubrication, causing bearings and other parts to be damaged, especially at high speeds. After changing the engine oil, the user should rotate the engine crankshaft with the crank a few times and let the vehicle run at a moderate speed for a few minutes.

Pay attention to lubricating oil to avoid oil loss.

Turbochargers use the same lubricating oil as the engine. In some turbocharged vehicles, there is no significant loss of oil during a change cycle. But in some other cars, the amount of oil loss is higher than normal, so it needs to be replenished periodically. Therefore, it is best for users to ask the car company for advice for instructions on checking and adding oil properly. Join CarOn to discover more about lubricants through the article below:

Thoroughly check the high-pressure gas pipeline system periodically

This is a part that is often forgotten when maintaining turbocharged engines. This is a quite serious shortcoming because just a small error in this system can lead to a decrease in boost pressure. At this time, the turbocharger needs to operate at a higher speed to compensate for the lost pressure, reducing the life of the system. Therefore, car owners should regularly check the high-pressure gas pipeline system to limit unfortunate damage from occurring.

Maintain the cooling system when refilling periodically

The turbocharger air cooling system needs maintenance every 160,000 km or sooner depending on operating conditions. Besides, you should also check the cooling system and change coolant regularly.

Replace fuel filter on time

The turbocharger uses exhaust gas from the engine and is therefore very sensitive to exhaust gas quality. If the fuel filter is dirty, it is easy for gasoline to be contaminated with impurities that will enter the combustion chamber. This greatly affects the exhaust system and directly harms the turbo. It is necessary to periodically check and replace the car fuel filter. Refer to the following article for more information about car fuel filters
