2-1/16" GM CAN-Bus Oil Temperature Gauge | 140–300°F with Warning

The GM CAN-Bus Oil Temperature Gauge reads oil temp data directly from the vehicle’s ECU through the OBDII CAN-Bus network, giving you a clean 140–300°F temperature range without adding an external sender when supported by the ECU. Built for 2008 or newer U.S.A. GM vehicles, it is designed for cleaner wiring, faster setup, and reliable oil temperature monitoring from the data your vehicle already provides. The integrated warning light adds a clear visual alert when oil temperature reaches the set threshold, while a microprocessor-driven movement and high-torque stepper motor keep the pointer smooth, stable, and accurate. Finished with a slim case, spin-lock mounting, solid aluminum bezel, and weather-resistant build, it is made in the USA and backed for life.
