    Switched over to power service because it was locally available and I wanted a winter specific formula (PS gray bottle).

    Now running PS white (summer).

    Both claim a cetane booster.

    XDP has a convenient measuring bottle (which was nice) but was a pita to pour into the tank. Cetane booster claimed also.

    Honestly, I'm sure additives are beneficial in lubricity (as claimed) but I've never really noticed a significant difference in how the engine runs.

    I'd like to try/run the stanadyne addatives, but I can't get them where I am. They seem to get good reviews From people who use them though.

    I've tried two stroke and ND30 W, MAYBE a little quieter running. I know at least one guy who could not pass emmisions on a 6.5 while using two stroke, which kind of makes sense when you think about what's actually going on there. I stopped using those and went to commercial addatives for my own reasons that I don't discuss on forums. Too much of a hot potatoe usually.....

    Typo? Or is the PS packaging different where you are? PS white should be the winter additive.
