Is this any good? My AmsOil rep gave me a bottle to try. Just wondering if any one else has used it.

I haven't tried the cetane booster,and I don't think it gets cold enough here in central GA to need it. But I do use their Diesel Fuel Modifier. An inquiry to Amsoil tech came back that it is neither an emulsifier nor a demulsifier and contains no alcohol and is intended for light duty rigs such as ours. It is intended to add lubricity, stability, etc. to the fuel.


I will say that I have used Amsoil products for about 30 years, and I've yet to find any product that didn't live up to their claims. My trust in them is enough that I purchased a dealership about a year ago when I retired.
