Immersion Heater 7.5in

The ALLSTAR PERFORMANCE Immersion Heater 7.5in (ALL 76416) is a 250-watt engine oil heater designed for cold-weather vehicle starts and winter storage protection. This immersion heater is ideal for mechanics, fleet operators, and vehicle owners in northern climates where cold-soak conditions limit pumpability and engine wear.

This immersion heater uses an internal electric element to warm engine oil directly within the oil pan, reducing viscosity and allowing faster, easier starts when ambient temperatures drop below freezing. The screw-in design with a 1/2 in NPT steel fitting integrates seamlessly into most vehicle oil systems without requiring major modifications. Rated for 120V household current, this unit draws 250 watts of heating capacity and arrives with a 12-inch power cord for convenient outlet access.

Using an immersion heater for a few hours before startup significantly reduces metal-to-metal friction during the critical first moments of cold ignition, extending engine life and improving fuel economy. The steel NPT fitting ensures reliable sealing and corrosion resistance typical of engine block applications, making it a reliable choice for winter vehicle maintenance.
