What engine wear can be avoided with a Kim Hotstart product for preventive maintenance?
Lots of bad things happen to engines when you turn them off after they have been running. The oil is very thin when it is hot so it flows very easily, and when the engine shuts down the warm, thin oil drains into the oil pan. If the engine sits for a period of time the cylinder walls and pistons drain most of the protective oil back into the oil pan leaving dry surfaces. Meantime, as the hot oil cools and drops below 80F moisture condenses and sludge is formed on the top of the oil. This sludge contains acids and water which are by-products of combustion. As the engine cools further the oil gets thicker. The colder the oil gets, the thicker it becomes making it more difficult to pump. When the engine is started the crank must rotate through this very sludgy oil while the pistons move up and down on dry cylinder walls. This will continue, even after the engines starts, until the oil warms enough to be easily pumped to all moving parts. Tests have shown that 80 to 90 percent of engine we
