While the viscosity of any fluid is always relative to what it’s being compared to, we’re specifically discussing some of the newer “ultra-low” viscosity oils — like 0w-16 or 0w-8 ...

Oils do more than just lubricate our cars’ engines—they help protect all the internal components and keep the powertrain ...

Motor oil comes in a variety of forms, designated by pairs of numbers, but the most common two are 10W-30 and 10W-40. What's the difference between them?

Everyone knows that regular oil changes are important for an engine's longevity. But what does motor oil do, and does getting ...

One way to do that is by using a low viscosity oil. The less energy an engine uses to lubricate itself, the less gas it uses in the process. There's also the fact that as engine technologies and ...

In the United States heavy duty trucking lubricants market, the drive for energy efficiency is influencing a transition from SAE 15w-40 diesel engine oils to those with lower viscosity grades such ...

“This equipment manufacturer recommends low viscosity engine oil SAE 5W-40 for temperatures ranging from -22° F to 120° F and SAE 15W-40 from +15° F to 122° F,” says Mark Betner, heavy ...
