SynDiesel┬« is trademark was created in 1996 when Jess Hewitt was blending diesel fuel for over-the-road engine applications.  A new synthetically produced diesel fuel blendstock was introduced into the United States.  The technical attributes of the blendstock were remarkable as the cetane was very high, no sulfur and the stability was unparalleled.  While using the product as a blendstock Mr. Hewitt began investigating its use as a high performance fuel and as a remote generator fuel. 

After many trials, a test batch of the first synthetic diesel fuel blend was compounded and tried on regular diesel engines.  The results were very satisfying with remarkable improvement in power and reduction of engine noise.  Emissions reductions and high thermal stability were also noted. 

The first product offering was made on the website in 1998.  The first SynDiesel products were sold in packages for remote generators and high performance diesel engine use.  SynDiesel has been a part of every major diesel land speed record in the past ten years.

 Fast forward to 2018, SynDiesel now is in its 20th year of use and is making significant inroads to more standby and remote generator.  The main attraction of the fuel is its thermal stability.  In addition, a SynDiesel Arctic diesel was created for use in Sub-Zero temperatures down to -70F.


The SynDiesel trademark was created to identify the synthetically produced diesel fuel as a separate product.
