These engine parts are from a teardown of an engine using an experimental low-HTHS viscosity oil. A visual inspection shows no noticeable differences in wear between it and the higher-viscosity oil.

Polymer flooding is among the most researched and utilized methods to improve oil recovery. Polymer solution viscosity is the primary governing parameter that aids in lowering the mobility of the ...

Crude oil derives, by way of geological processing, from organic material initially buried in sediments at the bottom of ancient lakes and oceans. Crude oil formed at depth in a sedimentary basin ...
