Video: Oil Filter Bypass Valves & Filter Capacity

When a system is in bypass, contaminants are not being filtered out of the oil. This video is sponsored by FRAM.

Over time, an oil filter can collect enough contaminants to become restricted. The engine can sense that the filter is blocked by the pressure differential between the oil going into the filter and the oil going out.

If the difference in pressure is great enough, the engine will bypass the filter media to keep the oil pressure and starving the bearings for oil. When a system is in bypass, contaminants are not being filtered out of the oil. This is fine if the oil is cold during start-up. Over a longer period of time, however, wear can be rapidly accelerated. In this video, Andrew Markel makes the connection between oil change intervals and oil filter replacement.

The Science of Advancing Sustainable Tires

The chemical and physical makeup of tires will evolve via new materials and sustainable compositions.

With vehicles of the future being evermore developed with the promise of autonomy and digital connectivity, manufacturers of the tires that carry those vehicles are also expected to upgrade their level of intelligence and electronics.

But it’s not always about the gizmos and gadgets we’re adding to those tires. What you might call the meat and potatoes of tires – their chemical and physical makeup – will also likely evolve via new materials and compositions.
