A turbocharger – what is it? How does it work? How to care for it? And what to look out for when looking to buy a used turbo car?


Modern technology with its innovative and creative solutions in car manufacturing allows mass production of car engines that provide maximum power with optimum fuel consumption. More and more engines nowadays are equipped in a system supplying extra engine power regardless of number of cylinders and its overall capacity. The most popular solution that delivers extra engine power is turbocharger. It is a very efficient device but it requires special treatment and care.

Devil is in the detail

A turbocharger is part of the engine and is a result of many years’ research and effort to find a solution that provides an increase in engine power with a decrease in its weight and fuel consumption at the same time. It consists of two key elements: a turbine and compressor installed on one axis. Combustion gases directed at the turbine power the compressor rotor that then forces more air into the engine cylinders. This allows more fuel to be combusted within the same chamber capacity and by doing so increases the engine’s efficiency and power output.

Where can we find turbochargers?

Historically, turbochargers were installed in sports cars to achieve an increased engine power without increasing overall car weight. And we know the lighter the vehicle, the faster it will be. This was a vital principle in sports cars.
When it comes to utilizing turbochargers in standard cars, the manufacturers put emphasis on fuel economy and green driving rather than speed. A turbocharger lowers overall fuel consumption and helps out the environment.
A turbocharger is also a practical solution in Diesel engines that due to their construction have less capacity; therefore, a Diesel engine to achieve power comparable to a petrol engine would need to be a lot larger and heavier. This in turn would contribute to increased combustion and emission of harmful gases to the atmosphere. A turbocharger then provides extra power without increasing the car’s weight.

How to care for a turbocharger?

A turbocharger is a very complex device exposed to powerful forces and extreme temperatures during its working cycles. A turbine rotor revolves at the impressive speed of 200 000 revs/min and in petrol engines the temperature of the combustion gases reaches up to 900°C. In such extreme conditions appropriate oils need to be used as sufficient lubrication is key and will provide long lasting care and conservation of the turbocharger.

. Therefore, it is important to follow the manufacturer’s recommendations with regards to the engine oil that need to be used.

How to care for your turbo:
• Use only approved engine oils recommended by your car manufacturer
• After you start the engine, before you start driving, let it warm up on neutral geal. It allows the engine oil to get where it needs to, in particular to the turbocharger
• When the engine works at high revs, it is not advisable to switch it off suddenly. After a long and dynamic driving, it is recommended to leave the car on neutral gear for a few seconds to allow the turbocharger to slow down its movement before you switch the engine off. This practice will extend the life of your car turbo.
• Exchange an air filter regularly; this will prevent any dust and debris getting inside the engine and turbocharger alongside the air.
• Check the level and quality of the engine oil on a regular basis. Low level of the engine oil or dirty oil will contribute to irreversible damage in the turbocharger and engine.

Buying a used turbo car.

Since turbochargers are now commonly used by the motor industry, it is now vital to recognize signs of turbo malfunction when you decide to buy a used car that has this device fitted. Inappropriate turbo care and exploitation may lead to its premature failure.

What to look out for?

The very first sign that the turbocharger is not functioning properly is an increased engine oil usage and decrease in power. This, however, is often difficult to diagnose before buying a car. Visual assessment of the turbocharger may help here- presence of small oil stains is perfectly normal but excessively oily and dirty or sterile clean looking casement should raise our suspicion. A very effective way of checking how the turbocharger is doing is the boost pressure measurement carried out by a specialist garage.

faulty turbo problems

However, if you happen to buy a used car and it turns out that the turbocharger is faulty, that’s not the end of the world. In the majority of cases, it just needs to be reconditioned by a workshop specializing in turbocharger reconditioning. The cost of reconditioning and fitting is usually about £550 depending on car make and model.
Before you decide to choose a particular workshop that brings old turbos back to life, it is vital to consider their warranty conditions and their reputation.
