Blue smoke = oil. Black smoke = too rich a fuel mixture. White smoke = moisture, either condensation in the oil or leaking coolant. Do you have a thermostat installed in the upper radiator hose? IMHO adding any of the 'snake-oil' products sold today are really not doing anything but thinning out the oil and or gas depending on where you are adding it. It may loosen some crud, and will not hurt anything internally and you can get the same thing from mineral spirits, which is the main ingredient in all those products anyway. You could just dump some paint thinner or charcoal lighter fluid in as they are 100% the same thing, and cheaper than the commercially sold products, about $10 per gallon. I agree with John. It's a lot of work to tear down an engine and so why not do the job right the first time?
