Understanding Oil Viscosity
Viscosity is the measure of a fluid's resistance to flow.
Why Do Motorists Change Oil in the Spring and Fall?
Spring and fall constitute “oil-change season” for many, but that schedule is more tradition than a maintenance imperative.
Should I Use a Lighter Winter Oil Weight?
Using a lighter winter oil weight when the temperature drops can improve cold starts and maximize wear protection at startup.
How to Read a Gear Oil Viscosity Chart
This comparative viscosity chart can help determine if two or more lubricants have similar viscosities.
5W-20 vs 5W-30 vs 10W-30: What’s the Difference?
The primary differences are their viscosities when cold and once your engine has reached operating temperature.
What Happens if I Use A Thicker Oil in My Engine?
It's best to use the recommended viscosity, but a slightly thinner or thicker oil likely won't cause harm.
Which Car Oil is Right for my Vehicle?
When deciding which oil to use in your car, ensure you use the correct viscosity of oil that meets the...
How Does Synthetic Motor Oil Increase Fuel Economy?
Synthetic oil allows for lower viscosity without compromising wear protection and better cold-flow, both of which improve fuel economy.
