Often asked: Does Synthetic Oil Improve Fuel Efficiency?

Does synthetic oil give better fuel economy?

Synthetic motor oils have oil molecules of a small uniform size as compared with those of regular non-synthetic oils. This decreases friction and improves fuel economy. Synthetic motor oils vary but some companies claim gains of up to 5% in fuel economy just by switching your stock motor oil to their synthetic brand.

What oil is best for fuel economy?

Fuel-economy oils have become popular over the last several years, especially the 0W20 and 5W20 oils. Most of these oils will provide at least a 1- to 2-percent increase in fuel economy over using the next viscosity grade.

Does fully synthetic oil make a difference?

Because synthetic oil is better on your engine and has fewer impurities, it can go longer than conventional oils or synthetic blends. Newer cars may be able to go 10,000 miles or only need an oil change once a year. Turbo engines and older cars may still require oil changes every 3,000 to 5,000 miles.

Does synthetic oil add horsepower?

Synthetic oils (right) have molecular shapes and sizes that are identical, reducing the internal friction in the oil. The reduced friction benefits the engine on cold startup, increases fuel economy, and can improve engine torque and horsepower output. In most cases, synthetic oils outperform mineral oils.

Does thicker oil affect gas mileage?

The thicker that oil is, the more energy it takes to pump that oil, which uses fuel. “So the difference between an XW-30 and a XW-40, you see a fuel economy different more related to the 30 vs. the 40 rather than the 10W vs. the 15W.”

Which is better 5w30 or 10w40?

The first number in the motor oil’s name describes the oil’s cold viscosity. A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
