Engine Oil Pre-Heater

The MOROSO Engine Oil Pre-Heater (Part #23990) is essential equipment for serious enthusiasts who demand optimal engine performance in cold-start conditions. Designed for mechanics and performance-minded drivers, this 212-watt heating unit addresses the issue of cold oil reaching the engine's bearing surfaces slower than fuel ignition, which can lead to unnecessary wear during startup.

This internal immersion-style pre-heater operates at 212 watts, providing consistent thermal energy directly to the oil reservoir before engine start. Its compact design measures 4.3 x 4.3 x 6.6 inches and weighs just 1.45 pounds, allowing for straightforward installation into most standard oil pans without significant modification. By raising oil temperature before ignition, the unit dramatically reduces viscosity, enabling faster oil circulation through galleries, hydraulic lifters, and bearing surfaces.

Professional mechanics rely on the MOROSO Engine Oil Pre-Heater for race-prepped engines, storage-condition vehicles, and cold-weather operation. This product is particularly beneficial for those operating in harsh winter climates or working on high-performance builds and vintage restorations, ensuring improved reliability and extended component life.
