What has the EPA/Refineries taken from #2 Diesel?

[DLazok]

Besides a gasser, I also drive an F-250 6.0 PSD. Had a 7.3 when Diesel #2 was heavier and only cost a buck. Nowadays, the fuel looks lighter, smells lighter, and (on ULSD) my conservative driving is yielding -2 MPG in combo L.A. freeway driving.
Most of us Diesel folk use an additive like STAN... or POWER... at the recommended dosage, so lubricity concerns are not top on the worry list. My question is:
How much oil (or BTU content) has the government taken out of Diesel#2 (summer blend) and will it hurt our injectors, pumps and other hardware in the long run, all in the name of less particulates? I notice (on my almost stock truck [just a 4" CAT-back exhaust]) that the get-up and go has left, as did the smoke, and fuel mileage.
Our engines cost an extra $5K or $6K per vehicle. I don't want to ruin it. What can we do?

All are valid concerns. Take a look at this product that was developed specifically for ULSD. https://www.amsoil.com/lit/databulletins/g2236_rev1_07.pdf .

Here is a Q&A on the new ULSD. https://www.amsoil.com/dealer/onevoice/OneVoice_ADF.pdf .

Hope this helps.

Removing sulphur removed lubricity.
ULSD additives are designed to lube without raising the sulphur content. I was told the cetane dropped, hence mileage too. Dunno.

actually cetane should increase, but it is total enegy content that has dropped (BTU's) supposedly about 2%.

It is somewhat interesting that in the clean air zones of 110 eastern Texas counties under TxLED requirements that min. cetane number of delivered fuel is supposed to be 48 or better.

Go to link, click on Background link, and go to first Rule link for Clean Air diesel standard.

somewhat interesting, Viscon just had their alternative diesel formula approval rescinded.
Different note, after the scare last year that bio-D would not be available in these counties, the board changed the position and certain bio-D blends and distribution of bio-D is allowed .
