Laboratory Facility controlled evaluations are much more accurate for testing the Fitch Fuel Catalyst than
field testing. There are many variables in the field that influence a test and make it very difficult to gather
precise data. If a field test is the only alternative, here are some recommendations for conducting the evaluation.
Bullet points for evaluating fleet vehicles
Winterized -Diesel fuel number 2 (DF2) loses its ability to flow at temperatures below 20F (-7C.). This is caused
by wax separation, and is commonly termed "gelling". The thicker wax component of the fuel may be blocked by
the fuel filter although it can flow through the larger diameter fuel lines. Most fuel companies "winterize" the fuel
sold during winter months in cold climates. This winterized fuel resists gelling at low temperatures. The winterized
fuel does not provide the same level of performance as the summer fuel, so your mileage will likely drop while using
it. The same brand name may be different in Maine from the product sold in New York and in Florida. Diesel fuel
consists of many different hydrocarbon molecules of varying characteristics, and of special interest is the
temperature some solidify and become wax. The appearance of wax crystals is called "clouding", and the
temperature at which this happens in a particular blend is referred to as "the cloud point". Lowering of the cloud
point is generally done by addition of heavier (higher boiling range) components (Napthalenes and aromatics)
and other additives, but this also reduces fuel energy and consequently mileage suffers. Winter fuel is less
economical and lighter than heavier summer fuel.
Field testing of the Fitch Fuel Catalyst will take an enormous amount of time to conduct an evaluation accurately. Advanced Power Systems Inc, has independently contracted laboratories to perform these such tests and these reports are readily available upon request. These independent laboratory tests are much more accurate than any type of field evaluation.
