I don't know if this matters or not... but since we're on the subject of coolant.... I have had an abnormal amount of oil in my coolant water (missing the same amount of oil from the crankcase) after using WaterWetter (which I will no longer use... don't really need it anyway). Strange enough, if I use just water and antifreeze, all is normal... if I use WaterWetter, within 1 day I have oily water (same color as crankcase oil) and am missing crankcase oil... If I don't use WW, I never miss oil from the crankcase and my water stays clean... besides suggesting the obvious (such as don't use WW) Can anyone explain this.....
I understand that WW can free up dirt and contaminants and get an oily film... but to be missing crankcase oil, only to have it collect in the overflow bottle enough to stain the bottle near-black... is this normal behavior for WW?
In any case, I'm not using WW anymore... though Redline's fuel injector cleaner seems to work extremely well.
