Thick Oil In Engine. What Is The Thickest Motor Oil Made The cons of using a higher viscosity oil in your older engine • Poorer circulation— A higher viscosity oil has more internal friction, resulting in slower flow As an example, a 15W-40 oil has a viscosity grade of 15 at 0°F and a viscosity grade of 40 at operating temperature (212 °F)

10W-30, 20W-50: Oils with two numbers are "multi-viscosity" and provide viscosity coverage across varying temperature ranges The cons of using a higher viscosity oil in your older engine • Poorer circulation— A higher viscosity oil has more internal friction, resulting in slower flow

The oil won't form a consistent lubricating film, allowing metal-to-metal contact and wear. • More friction and wear in bearing areas— Oil's main jobs are to protect, lubricate, and remove heat Thicker oil can reduce fuel efficiency, resulting in higher costs at the gas pump
Thicker Oil For High Mileage Engine. • More friction and wear in bearing areas— Oil's main jobs are to protect, lubricate, and remove heat The second number represents the viscosity at operating temperature
Deciphering Viscosity Discover Which Motor Oil Is Thickest and Why It Matters. The oil won't form a consistent lubricating film, allowing metal-to-metal contact and wear. A thicker oil, because it doesn't flow as well, can't remove heat as well as the recommended weight oil.
