It also provides superior wear protection and maintains its viscosity longer between changes. This oil also serves as a critical coolant, absorbing and carrying away the intense heat generated by the combustion process and mechanical friction.
The "W" stands for winter, indicating the oil's cold-flow properties; the lower this number, the easier the oil flows when starting in cold temperatures. Furthermore, it plays a vital role in cleaning the engine by suspending contaminants and combustion residues, preventing them from settling and forming damaging sludge.
