If you read the instructions on the Lucas Coolant Additive it says do not use distilled water. I called them and also did some research which is why I use filtered drinking water, not spring water.
I was having a rust issue every year. I was using distilled water and tried every additive from water pump lube to Water Wetter and combinations of them. Still had rust every year when I drained to put antifreeze in for the winter. When I purchased the Lucas I was all set to use distilled water until I read the instructions. Used filtered drinking water and for the past 2 years no rust at all. This is with an iron headed SBC.
Your results may vary and many swear distilled is the only way to go, but I know what works for me.
