Turbochargers have become widespread in modern cars. A mechanic quoted by Motorpasión estimates that 98% of vehicles use one, although the exact figure may vary. Their popularity is linked to manufacturers’ efforts to reduce engine size and emissions while retaining competitive power. Turbocharged engines also provide the strong low-rev response that many drivers have come to expect.

The system uses exhaust gases to drive one turbine, while a second turbine compresses air and sends it back into the cylinders. This increases the energy produced during combustion, but both turbines operate at extremely high speeds and temperatures. Engine oil helps lubricate the turbo and reduce heat, making correct oil levels and regular servicing important.

A video featuring the mechanic suggested servicing the turbo every 10,000 kilometres. That interval may be cautious, but it is not a universal requirement. The more practical recommendation is to follow the maintenance schedule in the car’s service book. Drivers who regularly use their vehicles in sporty conditions may benefit from shortening those intervals because the turbo is placed under greater strain.

Turbocharger failures can be expensive, with repairs potentially exceeding 1,000 euros depending on the system. There are also simple habits that can help reduce stress after demanding journeys. Following a long trip or sustained high-speed driving, it is advisable to leave the engine idling for a few minutes before switching it off.

Turning the engine off immediately after heavy use can leave the turbo very hot while stopping the flow of oil that helps manage its temperature. Over time, this can degrade the lubricant and contribute to damage to the turbines.
