ULSD in older engines-emissions - Scott Forman - 01-29-2008 11:34
I know that ULSD results in greatly reduced emissions from the engines
designed to run on it, but is it any cleaner in our old engines? Just
curious.

I'm sure it is possible to debate what-all makes up "cleaner," but the basic
equation is simple:
Less sulphur in equals less sulphur out. So for that particular byproduct, all
engines are outputting far less of it than they were, when run on ULSD.

In theory, ULSD, would have fewer sulphur-based emissions in any
engine using it. There are some issues with fuel system hoses and
seals on older vehicles (pre-90, probably), so you may need to watch
for fuel leaks and plan to upgrade/replace the flexible fuel lines.

Less sulphur means less sulphuric acid in the exhaust circuit. Pipes
and muffler may last a little longer.
