I have been using Standyne Performance Formula for the past couple of months......was recommended by the Bosch FI Shop......

Because I had already done a LM Diesel Purge, and had been using Power Service (Silver Container)......before I got to the Bosch folks here locally.....I don't have any data as far as my OM617.952 is concerned.....however, because the Bosch FI folks had such high regard for Standyne Performance Formula, I tried using it in a Yanmar excavator, that was experiencing a loss of power and smoking heavily.....have used about half of the container (30 gal fuel).....and the excavator performance has improved markedly....not smoking at all, power has returned......

Standyne Performance Formula cost is $10.00 per container...treats 60 gallons

Power Service, Silver is about $7.00 per container and treats 50 gallons at it's maximum Cetane boost of 6, or 100 gallons for a Cetane boost of 3

So, I think I will eventually run the Power Service for the most part, and a container of the Standyne every 3 months or so.......
