Keeping a close watch on oil temperature is essential when your engine is working hard. The Speco Oil Temperature Gauge is a smart upgrade for street machines, classic restorations, kit cars and hot rods running compatible petrol engines, giving drivers clear visibility of engine oil thermal performance. Designed as an electronic analogue instrument, it monitors engine oil temperature via a paired sending unit. Using a thermistor that changes resistance with heat, the gauge converts temperature variations into a precise electrical signal — allowing quick and accurate readings of engine thermal trends under performance loads.
