Turbocharged Car Maintenance: 5 Things You Should Never Do

Turbocharged Car Maintenance: 5 Things You Should Never Do

Turbochargers are amazing pieces of engineering that can dramatically boost a car's performance. However, they require specific care and attention to ensure longevity and optimal performance. Neglecting these crucial maintenance tips can lead to expensive repairs and potentially damage your engine.

Here are five things you should never do to your turbocharged car:

1. Hard Acceleration Immediately After Startup

When you start your turbocharged car, the engine oil needs time to circulate throughout the system, including the turbocharger bearings. Immediately accelerating puts immense pressure on the bearings before they're properly lubricated, leading to premature wear and tear. Instead, let the engine idle for a few minutes to allow the oil to reach all critical components.

2. Ignoring the Cool-Down Period

Turbochargers generate immense heat during operation. After a spirited drive, the turbocharger continues to spin for a while, generating significant heat even with the engine off. It's essential to let the car idle for a few minutes to allow the turbocharger to cool down gradually. This helps prevent thermal stress and potential damage to the bearings and seals.

3. Lugging the Engine

Lugging the engine occurs when you drive at low RPMs with high load. This puts strain on the turbocharger, forcing it to work harder than it should. Avoid driving in this manner, especially for extended periods. Shifting gears appropriately and maintaining a reasonable RPM range will help protect your turbocharger.

4. Using Low-Octane Fuel

Turbocharged engines require high-octane fuel to prevent knocking or detonation. Low-octane fuel can cause premature ignition, leading to engine damage, especially under high boost pressure. Always use the fuel type recommended in your owner's manual.

5. Aggressive Throttle Application When Exiting Corners

Sudden and aggressive throttle inputs while exiting corners can cause a surge in boost pressure, potentially exceeding the turbocharger's limits. This can lead to overboost, damaging the turbocharger or other engine components. Accelerate smoothly and progressively, allowing the turbocharger to build boost gradually.

Conclusion

Turbocharged cars offer exhilarating performance, but they demand careful maintenance. By avoiding these five common mistakes, you can significantly increase the lifespan of your turbocharger and ensure optimal performance. Remember, regular maintenance, including oil changes, air filter replacements, and inspections, is crucial for keeping your turbocharged engine running smoothly.
