As far as soluble oil goes, I have seen it work very well. My fathers Model A set idle for about 20 years with a mixture of soluble oil / distilled water. When I removed the radiator, the radiator shop wouldn't charge me a dime because it was clean. I run anti freeze now, but always wondered how much soluble oil should be in the water. What's the mixture? Anyone know??
