Diesel Fuel Quality is a Question Not a Guarantee

John T. Nightingale
Dieselcraft Fluid Engineering

Thirdly, current fuel distribution methods also have a negative impact on the condition of the fuel at the time of delivery. In many cases, brokers control fuel sales to major distribution terminals and determine delivery dates. There is no telling how long that fuel has been in the distribution network and how many times it has been transferred. Seldom do these distributors filter the fuel as they transfer it.

The solution: Multifunctional diesel additive packages and hardware.

For your single vehicle or fleet the improvement of fuel quality by the use of additives and current technology is always a good choice.

Many diesel fuel additive packages address the key issues with respect to fuel performance; some improve fuel economy, increase lubricity, improving cold flow, and improve cetane number. And some only address the issue of rust and corrosion, but all should be considered.

Most diesel fuel additives contain combustion improvers that release oxygen during the compression stroke. This allows combustion to start sooner, providing for a more complete fuel burn. A more complete burn provides all the power your fuel and engine is capable of producing. As combustion improves and you get a smoother running engine, an increase in horsepower that improves fuel economy and the reduction in black smoke emissions.

Cetane is a performance rating of a diesel fuel, a higher cetane number or cetane rating indicates greater fuel efficiency. The fuel's cetane influences, duration of white smoking after start-up, drivability before warm-up, and intensity of diesel knock at idle. Increase the cetane number of a fuel and you have improved performance.

Bad Fuel Blows Up Engine, What Next?
(11/12/08 - 12:30 PM)

Excellent article, but I missed one critical thing. What recourse do you have when bad fuel blows up an engine?? We (QT Equipment) recently had this problem with a new chassis that was under warranty. The dealer and manufacturer (which will remain nameless for now) laid the blame on us. Without spending big bucks in attorneys fees investigating and going after everyone in the supply chain for diesel, is there anything else that can be done?
