What do Engine Oil Viscosity Ratings Mean?

The main function of motor oil is to lubricate the engine and its components. Oil viscosity serves as a very important part of the oil selection process, however this simply refers to the rate in which the oil flows through the engine. The higher the viscosity, the slower it moves; the lower the oil's viscosity, the faster it moves.

What do the Numbers Mean in 10W-30?

The initial number rating outlines the viscosity of the oil with a cold engine, while the latter references viscosity with a hot engine. The oil has to maintain this ideal equilibrium to coat the engine and its vital parts. A good oil will move while cold, but will also keep its form when it's hot.

Viscosity Recommendations

A qualified service technician will recommend low viscosity oil ratings at very cold temperatures due to the nature of oil. They typically will recommend high viscosity oil when the climate is extremely hot.

In summary, viscosity is an important part of your oil recommendation in regards to how it determines the lubrication of your engine during specific temperature settings. In Vienna, VA, the Honda service technicians at Honda of Tysons Corner can recommend the proper oil for your driving conditions.
