but isn't jet fuel blended with additives to prevent gelling or microbe

TDD

Nope, "Jet Fuel" as you call it is JetA50, and is the same thing a #1
Diesel, Home Heating Oil, and a few other names. The difference is,
that to be classed JetA50, and sold for Aviation Fuel, it MUST be
Filtered to FAA Spec, and be within the Specific Gravity, FAA Spec.
So, what the Distributer does, is he has only one Grade of #1 Diesel in
his tanks and when he pumps it for Transport to a customer, it goes thru
a different set of filtering for Aviation, than for Home Heating, or #1
Diesel, but it all comes from the SAME Tank. With #2 Diesel, in cold
climates, they have what is called "Winter Mix" where the Distributer
will mix #1 and #2 Diesel, to lower the GellPoint of the fuel when
loading the Truck or Barge, for deliveries starting about August, and
increase the Ratio of #1 to #2 the farther North and away from the coast
the fuel is destine for. For Gasoline, the distributer will have an
"Additive Package" that they add to the Tank when dispatching a Load,
designed for the prospective customer. Many times Shell, Chevron, and
Mobile Gas Stations, will get their fuel from the same Distributer or
supplier and the only difference in the fuel is the "Additive Package"
put in, as the basic fuel, ALL COMES FROM THE SAME TANK. Depends on who
owns the Refinery, or where the Distributer bough his fuel from, the
last time. I have seen the same truck at two or three different Brand
Gas Stations, in town, on the same day, delivering fuel. the distributer
is 250 miles away, so you know they didn't fill the truck three times
that day.


ISTR this is even true with pipelines. When company 'A' puts several
thousands of barrels of #1 'into' the pipeline company's head end, the
pipeline company will deliver the same number of barrels out the end
point without actually trying to calculate transport time or any such.
The fuel that goes into company A's tank could have just as easily been
put in by another company shipping the same product.

As it is a totally fungible commodity, the pipeline company just logs
how many barrels in one end and that many barrels belong to company 'A'
at the other end.

But as far as #1, truck fuel, and aviation, is it still all the same now
that road diesel has to be that special (more expensive) ultra-low
sulfur stuff? Or is home heating oil (#1) and aviation jet fuel also
ultra-low sulfur now?
