alternatively, you could buy a heat exchange unit. Basically it heats the engine faster and cools it better. It works by passing oil and water close together past a thin metal membrane (no it wont leak). When you statrt the cold engine, water heats up faster, the heat is the passed into the oil, providing better protection nd faster warm ups. When the oil is hot, it can pass this heat onto the water system, thus keeping the oil at the optimim thermostats temp....justan idea.
