Oil Temperature Gauges: Digital, Electric, & More
Mechanical gauges read the oil line directly, while electric gauges use a remote sender and keep hot oil out of the cabin. Digital gauges add a numeric readout and warnings.
Common scales are 100 – 250 °F and 0 – 340 °F, in 2‑1/16‑inch and 2‑5/8‑inch sizes.
