Effects of oil properties on spark-ignition gasoline engine friction
50
TL;DR: In this article, the effects of base oil, friction modifier (FM) and viscosity grade on firing engine friction were investigated in an automotive gasoline engine, and it was shown that replacing conventional oil with synthetic oil of the same visco-ity grade reduces friction, especially at high boundary friction conditions.

Synthetics basics: Polyalphaolefins — base fluids for high‐performance lubricants
R. Benda,J. Bullen,A. Plomer +2 more
TL;DR: Polyalphaolefins or PAOs are saturated oligomers manufactured via the catalytic oligomerisation of alphaolefs as discussed by the authors, which are then hydrogenated and distilled to produce a range of PAOs.
