Do turbocharged cars need to warm up?

Turbocharged cars do need to warm up. After ignition, the upper part of the engine is in a state without engine oil and lacks lubrication. It takes about 30 to 40 seconds for the oil to be delivered to components that require lubrication such as pistons, connecting rods, and crankshafts. Prolonged idling to warm up the engine not only provides no benefits for turbo maintenance but also increases exhaust emissions. The warm-up process only requires approximately 2 minutes. When the RPM reaches 1000, avoid rapid acceleration or aggressive maneuvers. Instead, adopt a gentle driving style, warming up while moving. Normal driving can commence only after the coolant temperature reaches the normal operating range. Idling to warm up the engine causes a slow temperature rise, and the main wear on the engine comes from cold starts. This method fails to effectively protect the engine, and incomplete combustion can also lead to increased carbon deposits.
When driving a turbocharged car, I briefly warm it up by waiting about 30 seconds after starting to let the engine RPM stabilize before moving. The internal bearings of the turbocharger rely on engine oil for lubrication. During a cold start, the oil is thick and flows poorly, so driving at high speeds immediately may lead to insufficient lubrication, damaging the bearings or even shortening the turbo's lifespan. From my experience, especially in winter, it's necessary to wait a bit longer to allow the oil to circulate properly, then drive slowly for the first few kilometers while controlling the speed. This protects the components and saves on repair costs—my friend's car, which didn't warm up, often had issues and required expensive repairs. Modern oils and designs have improved, but the habit of warming up extends the overall engine lifespan and makes high-speed driving safer.
As a long-time car owner who has driven several turbocharged vehicles, prolonged idling for warm-up isn't actually necessary. The key is lubrication – in cold weather, oil flows more slowly. After starting, wait for the dashboard RPM to drop before gently driving off. Avoid aggressive acceleration until the engine reaches optimal temperature to reduce turbocharger friction risks. Through testing, I've found excessive warm-up wastes fuel and increases emissions, while driving too hastily once caused bearing stiffness in sub-zero temperatures. Low-speed initial driving serves as effective warm-up, balancing protection and efficiency. Regular maintenance with quality engine oil can shorten warm-up time and ensure smooth vehicle operation.
When driving, I focus on practical operations, and the warm-up for turbocharging is brief. After starting the engine, there's no need to idle in place—just wait 10 to 15 seconds for the RPM to stabilize, then gently press the accelerator to move forward. The lubrication system ensures oil quickly covers the turbo, and driving slowly when cold avoids high RPM. Additionally, modern designs include oil cooling circuits to reduce the risk of damage. I never idle for too long during warm-up, as it wastes fuel and reduces efficiency. Instead, driving slowly allows the engine to warm up naturally, which is especially useful in icy conditions. Combined with winter-grade oil preparation, this approach ensures longer turbo lifespan without hassle.
