The turbo is one of the hardest-working parts of an engine, spinning hundreds of thousands of RPM. A few simple habits extend its life dramatically.
• Use manufacturer-approved oil of the correct viscosity and keep to change intervals.
• Do not push a cold engine right after start-up.
• After long/hard drives, idle for a few minutes to let the turbo cool down.
• Replace the air filter regularly.
• Fix oil leaks early.
• Keep up with regular service checks.
These steps lower both fuel use and turbo costs.
