Benefits of Turbochargers

Chart explaining benefits

Smaller engine + Turbocharger = Fuel economy + Power


Formulated for the extremes of turbocharged engines

Mobil 1 engine oil provides our best performance and protection from the punishing operating conditions of turbocharged engines.‡ Although turbochargers have several advantages, those advantages come with challenges - higher temperatures, higher rpm and greater compression. Hot exhaust gases blow directly through turbochargers, which drive the turbine fan, cause the turbine shaft to rotate rapidly and expose the entire turbine section to searing heat not found in other parts of the engine.

‡Mobil 1™ 5W-30 engine oil was evaluated against Mobil 1 ILSAC GF-5 product testing against limits in Honda HTT and GM Turbo Tes

While engine crankshafts average about 3,000 rpm at highway speeds, the turbocharger shaft can reach speeds up to 200,000 rpm. Oil in a turbocharger can exceed temperatures of 400 degrees Fahrenheit, which is about twice the average heat of non-turbo engines. Such high temperatures can cause some engine oils to decompose, resulting in engine deposits and diminished performance. But Mobil 1 oils resist breakdown by delivering outstanding thermal and oxidation stability, helping bring out the benefits of turbochargers. When used in turbocharged applications, Mobil 1 oils offer outstanding:

  • Protection of thrust bearing
  • Varnish control on shaft bushing
  • Deposit and buildup control on the compressor, compressor seal plate and turbo housing

Specially formulated to endure the additional stresses encountered in turbocharger applications, Mobil 1 oils deliver exceptional performance and protection at extreme temperatures - down to -40 degrees Fahrenheit and up to 500 degrees Fahrenheit.
