Engine PreHeaters

Engine Pre-heaters can save you big money by reducing the damage caused by cold starts, by extending your engine's life and reducing your expense at overhaul time. Significant engine wear can occur at startup, because the oil circulation system has not had a chance to pump oil to the engine parts. The thicker the oil, the longer this will take, resulting in less oil on running surfaces during the startup sequence.

Engine Preheating during extremely cold temperatures is one of those "ounces of prevention" that can keep cold starts from damaging your engine. Cold temperatures not only slow the initial movement of the oil but the differential thermal expansion of engine materials (aluminum and steel) decreases engine clearances, creating the potential for more accelerated wear during cold startups.

Engine Pre-heating makes a world of difference. It heats the oil so the oil is thin enough to flow through the engine and properly lubricate all of the critical wear surfaces. Engine Preheating also heats the metal parts in the engine. That's important because aluminum crankcases have a higher coefficient of thermal expansion than iron crankshafts. This means as your engine cools down, the clearance is reduced. And as a result, you may not have sufficient oil film thickness for proper hydrodynamic lubrication at very cold temperatures. In other words, the wear rate is going up.
