When you’re pushing your engine hard, oil temperature matters just as much as coolant temperature. The Speco Oil Temperature Gauge is a valuable addition to street machines, classic restorations, kit cars and hot rods running compatible petrol engines, giving you accurate insight into how your engine oil is coping under load. Designed as a mechanical instrument, it tracks engine oil temperature independently of the vehicle’s electrical system. Using a permanently attached, ether-filled capillary line connected to a sensing probe, it delivers quick and precise readings of engine thermal trends — especially during performance driving.

  • Accurate Oil Temperature Monitoring: Displays real-time engine oil temperature for informed driving and tuning decisions.

  • Mechanical Operation: Functions independently of the vehicle’s electrical system for consistent and reliable performance.

  • Ether-Filled Capillary Line: Permanently attached capillary tube transfers temperature changes directly from the sensing probe to the gauge.

  • Fast Thermal Response: Allows quick and precise reading of oil temperature changes under performance loads.

  • Supports Engine Protection: Helps identify excessive oil temperatures that may impact lubrication and engine longevity.

  • Included Brass Thread Sender Adaptors: Supplied with a 2-piece adaptor set for flexible installation.
