Buying a used Diesel
I am thinking about buying a used diesel. With the new low sulfur fuel how does this effect older engines?

Both Caterpillar and Cummins IN WRITING say all their on-highway engine are backwards compatible for ULSD.
Neither endorses the need for additives.
As John said, Cummins did have some issues with lift pump seals that leaked, requiring replacement-- not a big deal.
