I have an '86 T-bird (only 63K miles). Had a wild idea and wondered if anyone has tried it. Has anyone ever tried to use motor oil (new or old) in the cooling system instead of water + antifreeze ? Here's the logic, oil inherently would be non-corrosive to the pump, radiator, and engine block. It should likely do better (flow) under very cold conditions, eliminate sticky thermostates, and perhaps not need changing nearly as often. Oil operates under the exact same temperature conditions as standard coolant mix (though under comparatively higher pressure in the cranckcase). No more corrosion at hose junctions as well. I know the thermal characteristics are different (likely hotter) but my engine runs very cold in cold weather which causes very poor fuel economy. How 'bout it ?
