Shell Aviation is testing a new jet fuel additive designed to keep fuel and combustion systems cleaner, promising cost savings and environmental benefits.

The additive, similar to detergent fuel used in cars, was developed for the US military where engines operate at very high temperatures and has led to significant improvements, particularly in terms of engine maintenance.

The additive is now being tested by KLM on three Boeing 747-400s operating on the Amsterdam-Bangkok route, with preliminary results on cleaner engine running showing positive signs. More detailed analysis on particulate reductions is being carried out, and the trial is also being extended to short-haul routes. A full analysis is expected by the middle of the year, and the additive could be available to customers shortly after.

Royal Dutch/Shell Group managing director Paul Skinner notes that for years car fuel was treated as a commodity, whereas today there are a host of environmentally friendly fuel options, and predicts the same could happen in the aerospace sector.
