What is Diesel Fuel?

Posted March 31, 2010 9:00 AM by algaex

Diesel fuel is a very complex mixture of thousands of individual compounds with carbon numbers between 9 and 23 (number of carbon atoms per hydrocarbon molecule) Most of these compounds are members of the paraffinic, naphthenic or aromatic class of hydrocarbons (HC).

Classes and Properties

These three classes have different chemical and physical properties. The different relative proportions of the three classes is one of the factors that make one diesel fuel different from another. It influences fuel properties and affects its performance.

Up until about 15-20 years ago, refineries used only about 50% of a barrel of crude oil to make distillates such as gasoline, jet fuel and diesel. The remainder of the barrel of crude oil went to "residual oil". Today, as a result of different refining techniques and additive packages, the refinery uses 90% or more of the same barrel of crude, which clearly has consequences for fuel stability.

Debris and Degradation

More than 90% of the debris on filter elements and the sludge in our storage tanks is organic material, fuel and oil breakdown residue. In most cases, this debris is acidic and not good for your engine. It causes corrosion in injectors, pumps and storage tanks.

The solids that form as the result of the inherent instability of the fuel and the natural process of degradation will accumulate in the bottom of your tank. The sludge will form a coating or bio-film on the walls and baffles of the tank, plug your filters and impact combustion efficiency. Eventually it will clog fuel lines and ruin your equipment.

No need to "read the whole article" here.

The "whole article" is an advertisement for AlgaeX products, most notably a phenomenally expensive ($199/gallon) fuel treatment they call a catalyst, and a fuel line magnet, which works on the same "principles" as other fuel line magnets:

Weasel words (gullibility + ignorance) = profits

Kudos to Drew for pointing out the pseudo-science scammy nature of these infomercials and for speaking for the contributing community here, who do not want to be associated with, let alone be seen as actively promoting (by offering many pages of blog space) fuel line magnets, perpetual motion machines, HHO devices, etc.

CR4 should shut down all these "blogs" by AlgaeX.

With this post (and by shutting down one of these threads) Moose has taken a good first step. CR4 might try taking the high road, as reflected in some of the the more ethical magazines, where editorial and advertising departments are not one and the same. Yes, GS is all about making money, but throwing ethics out the window, can, in fact, reduce profits. (Read Collins's Good to Great.)
