Are you the proud owner of a turbocharged engine? Excellent! Then you know exactly what true drive is: instant response, confident acceleration, and that satisfying pull that makes you smile every time you press the gas. However, to ensure this power lasts for years to come, a turbocharged engine requires slightly more attention than a naturally aspirated engine. 

Below are simple yet crucial tips that will help extend the life of your turbocharged unit and keep it running smoothly for thousands of miles.

Oil: the life of a turbocharger

Turbochargers thrive on cleanliness, especially when it comes to oil. Always use high-quality synthetic oil that meets the manufacturer’s specifications. Don’t experiment with viscosity – any excess tolerances are unnecessary and dangerous. The turbocharger spins at incredible speeds, meaning even the slightest underfilling or contaminated oil can cause premature bearing wear.

If you’re in the Indianapolis area and don’t want to deal with all this on your own, the Indy Auto Man service station can handle any scheduled maintenance, inspections, and diagnostics for your turbocharged vehicle.

Change the oil more frequently than the manufacturer recommends – approximately 1.5–2 times more often. This is especially true if you enjoy active driving, are often stuck in traffic, or use your car in hot climates. Regularly check the oil level on the dipstick – turbocharged engines sometimes eat up lubricant, and even a loss of a few ounces can impact the life of the turbocharger.

Gasoline: only high-quality gasoline

 Fuel for a turbocharged engine is like fuel for an athlete: the system’s efficiency and health depend on it. Use gasoline with an octane rating no lower than the manufacturer’s recommended one. In most cases, this is 91 octane, but switching to 93 octane often makes the engine more responsive, especially under hard acceleration, and reduces the risk of detonation under load. Yes, it’s slightly more expensive, but the turbocharger will deliver a long service life.

Spark plugs: a small, but important detail

At first glance, this is a simple part, but for a turbocharger, it’s critical. Iridium or platinum spark plugs provide consistent spark formation and better withstand high temperatures. Monitor their condition and follow the replacement schedule. And if you like to “burn,” change them more often. After all, misfiring not only reduces power but also damages the catalytic converter, accelerating turbo wear.

After a spirited drive, time to cool down

After a spirited drive, don’t turn off the engine immediately. The turbo is hot at this time, and if you suddenly cut off the lubrication system, the oil in its bearings will literally boil. Let the engine idle for about 5–7 minutes; this is enough time for the components to cool gradually. An alternative is to install a turbo timer, which will automatically maintain the required pause after the ignition is turned off.

Monitor the intake

If you have a direct injection (GDI) engine under the hood, be sure to clean the intake valves of carbon deposits roughly every 40,000–60,000 miles. This procedure is best left to specialists: it improves mixture formation, restores a smooth idle, and helps avoid unstable operation during cold starts.

Also, regularly check the intercooler hoses and clamps. Air leaks or cracks in the hose can lead to reduced boost, loss of power, and even unfiltered air entering the cylinders. Radiators are a separate issue. Turbocharged engines require cooling, so don’t be lazy about cleaning the radiators of dirt, lint, and insects at least once a season.

Chip tuning: only with care

If you decide to upgrade, don’t chase big numbers. A light Stage 1 with proper tuning and maintaining factory limits is safe and will provide a noticeable increase in torque. However, aggressive upgrades without upgrading the cooling and intake systems, installing reinforced components, and monitoring engine parameters will significantly shorten the lifespan of the engine.

A turbocharged engine won’t last forever, but with careful care, the right fluids, and timely maintenance, it can go about 125,000–185,000 miles without a major overhaul. If you love the thrill of it, treat your engine with respect, and it will reward you with the stable performance and excitement you chose a turbo for.
