Can Using Vehicle-Compatible Oil Influence Gas Mileage?

In the course of normal operations, engine oil performs many vital tasks. One of these jobs involves helping your cylinders get more out of each stroke, which in turn helps your car get better gas mileage. The key to understanding this process is understanding oil viscosity.

Viscosity can be defined the way fluids move when pressurized at various temperatures. At similar temperatures, high-viscosity liquids are thicker in consistency than low-viscosity liquids and thus flow more slowly. For example, even in summer months, high-viscosity motor oils maintain their integrity in the harsh cylinder-environments and help to form seals around the piston-rings. This allows your pistons to get more out of each stroke and benefits your fuel-efficiency.

Viscosity ratings describe how your oil behaves under specific conditions, and you can use this information to make informed decisions when you select your replacement oil. Hot weather blends, good for summer use, usually have the numbers 10, 20, 30, 40, 50, or 60 on the bottle. Cold weather blends have a "W" after the first number and often work across several temperature ranges. Examples include 5W-30, 10W-30, etc.

While using the right oil for the weather conditions is important, it is just as important to keep your supporting systems in shape.
