PM-22 additive

Just got my 350 and it is my first Diesel (outside of tractors). The service manager said using an additive in the winter should be done and the rest of the year can't hurt and will probably give me an extra mile or 2 MPG. So I ordered a gallon of PM-22 off EBAY figuring I wont need winter additive for several months now. Is PM-22 really worth it? I live in NY with a centane level of 40 at the pump (or at least that is what they are labeled).

THOUGHTS?

Havent used any additive in mine, cant say whether it is worth it or not. I used to put 2 cycle oil in my tank on my old 7.3. But wont on this one.

Standard ASTM D975 specification for for cetane number in ULSD is 40.

So if your pump is marked correctly, the diesel fuel that you are buying meets the cetane number for ASTM D975 ULSD.

From Ford manual:

Diesel Fuel Additives

It should not be necessary to add any
aftermarket additives to your fuel if you
use a high quality diesel fuel that conforms
to ASTM industry specifications.

Aftermarket additives can damage the fuel
injector system or engine.
Use Motorcraft cetane booster or an
equivalent cetane booster additive if you
suspect fuel has low cetane. Use
Motorcraft anti-gel & performance
improver or an equivalent additive if there
is fuel gelling.

* * * *

You should use Ultra-Low Sulfur Diesel
fuel (also known as ULSD) designated as
number 1-D or 2-D with a maximum of
15-ppm sulfur in your diesel vehicle. You
may operate your vehicle on diesel fuels
containing up to 20% biodiesel, also
known as B20. These fuels should meet
the ASTM D975 diesel or the ASTM D7467
B6-B20 biodiesel industry specifications.
Outside of North America, use fuels
meeting EN590 or equivalent local market
standard.
