Does anyone out there use the Amsoil Diesel Modifier. Stanadyne Performance formula seems to be the most popular. I personally have been using the Stanadyne, I use amsoil in everything else on my truck and was just wondering everyones opinion on their Diesel additives. The downfall I see is that it doesn't have the Cetane boost in where the Stanadyne does. I run the additive mainly for the lubrication of the pump.
