Fuel oil reinjection has increased oil viscosity at Kirkuk making it more difficult and expensive to get the oil out of the ground.

A thin EHD film may be caused by excess load or temperature, a lower oil viscosity than is required, low speed or water in the oil.

The fluid most commonly used for miscible displacement is carbon dioxide because it reduces the oil viscosity and is less expensive than liquefied petroleum gas.

Some oil swelling may occur, and oil viscosity can still be significantly reduced.

Heat from the fire reduces oil viscosity and helps vaporize reservoir water to steam.

Oil recovery is improved by lowering the oil viscosity by injecting steam or hot water.

As the bearing rotates, oil is carried into the working part of the bearing, where it is compressed, with oil viscosity preventing the oil's escape.

In particular magnetoelastic sensors for on-line measuring of oil viscosity.

Actually the cold nature of the methanol gave the team a problem with oil viscosity.

It comes equipped with an oil cooler, which helps control engine oil temperatures at sustained high speeds and rpms, thus ensuring more stable engine oil viscosity.
