As piston rings and cylinder bores wear with use, more and more combustion gases pass into the crankcase. As the oil becomes more acidic from combustion gases, it begins to degrade and increases wear and tear on critical parts like the camshaft. Mobil 1 synthetic oil helps minimize wear in several ways to keep your engine running like new.* In industry-required tests to evaluate wear protection during commuter service and high-speed/high-temperature conditions, Mobil 1 5W-30 exhibited superior performance as compared with the ILSAC GF-5 specification.

*Tests conducted using Mobil 1 5W-30.

Mobil 1 is able to do this by:

• Neutralizing the harmful acids to protect critical engine parts
  
  
• Maintaining excellent viscosity control
  
  
• Providing exceptional protection and durability to help minimize the harmful iron particles that accumulate over time and increase wear
