The big problem in using additives to enhance #2 diesel fuel is that you do not know what is already in the blend. Using premium diesel should insure more consistency. I'm still looking

PREMIUM DIESEL
In recent years, environmental regulations have significantly affected diesel fuel formulation
and specification limits. The introduction of tighter limits, coupled with rapid changes in
engine design to meet new emission regulations, created the need to address several fuel
properties to ensure proper performance while minimizing engine maintenance problems.
Some fuel users believe that, under certain circumstances, they can benefit from diesel fuel
with properties modified beyond the minimum ASTM D 975 specifications. A number of fuel
suppliers offer these specially formulated fuels in addition to normal diesel fuel. Diesel fuel
with these modifications is often called premium diesel, although other names are also used.
The premium diesel concept differs from that of premium gasoline. Gasoline engines of
certain types and compression ratios require a higher octane number fuel to avoid knocking.
Therefore, all fuel suppliers offer a higher octane level of premium gasoline for these vehicles.
Conversely, premium diesel is typically related to varying multiple fuel properties. Some
of the more commonly modified fuel properties are: cetane number, low-temperature
operability, stability, lubricity, detergency, and heating value. The premium diesel fuel
suppliers tailor the specific properties of their premium diesel to match the various performance
demands in different marketing regions. The level of improvement in each property
usually varies from one supplier to another and may also vary from region to region.
Several organizations have proposed meaningful standards for premium diesel. The intent
of these standards is to ensure that all diesel fuel carrying the “premium” classification
provides significant functional benefits when compared to normal diesel fuel. Currently,
the National Conference on Weights and Measures (NCWM), the Engine Manufacturers’
Association (EMA), and the Alliance of Automobile Manufacturers (AAM) have made the
three most complete proposals. The NCWM’s premium diesel proposal has received the
most widespread support to date.
