I read an artilce in TURF a while back about new Fuel & Oil additives called ACES II & ACES III. I spoke with one of the co-owners of the company at length this morning and was wondering if anyone here is using their products. Apparently the 2006 Clean Air rules will be forcing fuel companies to reduce the amount of sulpher in the deisel fuel. This is supposed to cause more heat and friction which is not a good thing for a diesel engine. I am NOT a mechanic by any means, I just want to know if anyone has heard of these products and has tried, or is using them on a regular basis.
