I got this from another site,so I pass it along. I am not a chemist nor do I play one on tv.
Effective June, 2006 diesel fuel (No: 1 and No:2) is required to be
15ppm MAX on sulfur and will be called Ultra Low Sulfur Diesel or
ULSD. Current Low Sulfur Diesel (LSD) is nominally around 300ppm
Sulfur. This is an EPA TierII Clean Air Act mandate and 99% of the
reason Diesel has gotten so high in price compared to gasoline. I
know our little grey's are so fuel efficient, none of us spend a
great deal of time searchng for $$ for fuel, but I wanted everyone
to know that removing the sulfur also takes away the wonderful
benefit of lubricity. Lubricity in diesel is measured by a test
called the High Frequency Recipricating Rig or HFRR. We call it a
Heffer here in Texas ;-). The Europeans have been running on ultra
low sulfur diesel for quite some time and set the HFRR requirement
at 460 (the lower the better) and the EPA and ASTM set the US
requirement at 520. The number is the measurment of wear scar
similar to the wear we will see in our engines in the area which
does NOT get lubricated much by the engine oil cylinder walls and
injector pumps. Lubricity additves are added to the fuel at the
wholesale truck rack or at the loading terminals to meet the 520
spec. Look for a whole host of aftermarket lubricity additives to
come out, I suspect. Don't be fooled by those who advise to put a
few drops of oil in your fuel - that doesn't do anything but provide
the carbon molecules to build up and plug injectors and clog
valves. Also don't be fooled by what they call OFF Road Diesel (aka
Red Diesel or High Sulfur Diesel (HSD)) after June 2006, most
refiners don't have the tankage to keep both in stock so they merely
sell the ULSD as Off Road. With the requirement for ULSD at 15ppm,
there is no way to keep the refinery and terminal pipes and hoses
clean enough with any 300 or HSD around. HSD used to be about
3000ppm in the old days.
If I hear of anyone who has a national brand of lubricity enhancer
on the market that really works, I'll let the group know.
This ain't no bull folks - I'm an automotive engineer, tribologist
and work for refiner in operations (quality and laboratory
services). Most importantly I'm a proud owner of a 1979 model Mitz
D3000.
I bought about 15 "Heffers" last year to prepare for June - they
ain't the ones with four legs ;-) We spent $BILLIONS building the
equipment to reduce the sulfur.
