Uses
Pinus jeffreyi wood is similar to ponderosa pine wood, and is used for the same purposes. Crystallized sap of Pinus jeffreyi has been eaten as candy. The exceptional purity of n-heptane distilled from Pinus jeffreyi resin led to n-heptane being selected as the zero point on the octane rating scale of petrol.

As it mainly consists of n-heptane, Pinus jeffreyi resin is a poor source of turpentine. Before Pinus jeffreyi was distinguished from ponderosa pine as a distinct species in 1853, resin distillers operating in its range suffered a number of "inexplicable" explosions during distillation, now known to have been caused by the unwitting use of Jeffrey pine resin.

Taxonomy
Pinus jeffreyi is named for its discoverer, Scottish botanist John Jeffrey, who encountered it in 1852 near Mount Shasta. Pinus is Latin for pine.
