What fuel additives does everyone use? I use the PRI products both in my Diesel truck and on the boat now. If you have never used the PRI stuff before I highly reccomend it (No, I 'm not a sales person for it). My buds in Afghanistan are using it and it is working great for them (they get some really crappy fuel there). I use it in my 7.4L and it cleaned up the transom alot. Here is the website.
