Case of 12 Litres

AeroShell Oil Diesel Ultra is a fully synthetic, multigrade engine oil designed for use in the

new generation of compression ignition (Diesel) Aviation Piston Engines.

The formulation has been selected to be suitable in piston engines fueled by Jet A or Jet

A-1 and is designed for use in the latest highly rated turbocharged diesel engines under all

operating conditions.


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
