I used Power Service for several years in my '59 White's 220 Cummins. Whenever I fueled I would add at least a half gallon to the tank. This past summer I had to have the injection pump rebuilt. They found lots of rust inside the pump and we had to replace it with an updated pump. The owner of the injection shop recommended Howes Diesel Treat. I find it at Walmart and I use it now instead of PS.
The recommended ratio for PS white bottle is way less. I only add half a gallon or so to my 300 gallon tank. Overuse can cause bad outcomes. Not to mention 60 years of wear & tear & potentially wet fuel.
