- 2010–2011 Single-source
Wikipedia's High Feature engine article gives the SRX application years (2010 to 2011) and Wikipedia's SRX article names the code LF1 in its infobox; GM Authority's January 2011 news post on the turbo SRX also names LF1 for the SRX but prints no model year, so it backs the code only; the Chevrolet Equinox and GMC Terrain share the code (GM Authority's pages on them); no factory page in the archive

Documented applications
This page aggregates every documented appearance of LF1 in the Cadillac reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
