I run stanadyne and am very pleased with the results so far. I am exploring the idea of adding 2stoke oil as well. Will this further improve the performance of my duramax?
Does anyone else use 2 cycle oil in their diesel? I add 12oz of 2 cycle oil to every fill up and the truck runs quieter and is more responsive. The oil more than makes up for the lack of lubricity in ULSD.
