AeroShell Oil Diesel Ultra is a fully synthetic engine oil containing a unique additive
package to provide superior piston cleanliness, resulting in a clean, efficient and reliable
engine. This package includes a powerful surface active additive, which bonds to the
surface of highly loaded engine parts, protecting the engine from scuffing damage.
This oil has been developed to provide excellent component wear protection and engine
cleanliness, based on substantial engine and component endurance tests with all the major
diesel aero-engine manufacturers, and flight experience with diesel aero-engines in the field
over recent years.
AeroShell Oil Diesel Ultra has been developed to be suitable for use in engines burning Jet
fuel and its performance has been optimised to cope with the demands of this unique type
of engine/fuel combination. Its key performance features include the ability to sustain high
bearing loads, neutralisation of acid build up from the sulphur present in the fuel, and high
dispersancy to allow for the relatively high particle loading produced when burning Jet fuel.
AeroShell Oil Diesel Ultra MUST NOT be used in spark ignition or Avgas powered aircraft
