An engine oil has seven basic functions. LUBRICATING the moving parts and reducing friction in an engine comes to mind as obvious. COOLING, as much as 40% of engine cooling is facilitated by the engine oil. SEALING pistons, rings and cylinders and supporting mechanical seals. TRANSFERING power as in hydraulic lifters. CLEANING and preventing sludge. DAMPING shock by absorbing energy spikes. PREVENTING or minimizing corrosion of internal engine parts.

As we all know, many upgrades can be made to a production automobile. An engine oil upgrade is probably the easiest to accomplish. Consider an AMSOIL engine oil and filter upgrade!
