Abstract
The problem was to determine if shear (slipperiness) characteristics differ between various SF motor oils. Oils tested met SAE (Society of Automotive Engineers) lOw-40 viscosity requirements, and API (American Petroleum Institute) engine service classification requirements for 1981 SF quality motor oils.
Four basic types of oil were tested: (a) mineral; (b) synthetic; (c) friction modified; and (d) extended drain. A gravity powered device was designed and used as a testing apparatus to measure force needed to pull a weight across a lubricated surface.
Findings indicated that friction modified oils (Pennzoil P-Z-L and Arcographite) were the most slippery. Other oils tested, in order of slipperiness, included; Valvoline, Phillips 66 Trop Artie, and Quaker State Deluxe. Least slippery (and most expensive) of the oils tested was Amsoil.
