I, too, have driven Saabs for more than 40 years and never knew of their water injection kits.

In the mid 50s my brother had a Buick straight eight in which he burned the cheapest fuel he could find. The car had a water injector, don't know if it was a Thompson, but it worked beautifully. As long as there was water in the under hood tank (it held a quart or two), the engine ran smoothly and quietly. As soon as the water ran out, it pinged mercilessly. He loaned the car to me for a couple of weeks and I learned to fill up with water whenever filling the gas tank. I can't say that it improved gasoline mileage, but it certainly did permit the lowest cost fuel to be used.

eBay a few years ago had a number used water injection kits for sale. Some may still be available. As I recall they ran in the $40 - $ 60 range.
