Chatsworth Engine oils are manufactured from
blends of high quality base oils and modern additive systems.
They are suitable for use in naturally aspirated diesel and
petrol engines in certain classic and vintage vehicles.
Chatsworth Engine Oils may also be used in many
stationary engines operating under moderate service conditions.
• Controlled detergency/dispersency
to give less carbon build up and for effective sludge control.
• Good thermal and oxidation stability.

Donington 40 is a ‘straight’ non-additive
type monograde engine oil of the type commonly used by the
original makers of vintage and veteran vehicles.
Donington 40 is recommended for use in
total loss lubrication systems fitted to these very old machines
where the engines operate under low to moderate speeds, loads
and temperatures. In these conditions, Donington 40 will provide
effective lubrication to minimise wear and effective gas sealing
of combustion zone.

SAE 50 monograde engine oil with high levels
of detergent and dispersant. Antiwear additives and corrosion
inhibitors are incorporated to give an excellent level of
overall performance.
Suitable for use in certain vintage and
classic vehicles. API SF/CD

A high quality premium grade, non-detergent
engine oil often preferred by owners of pre-war Classic and
Vintage vehicles. Being a non-detergent type of lubricant
it is important to ensure that the engine oil is changed at
least every 1000 miles. This grade is also ideal for total
loss lubrication systems used in the engines of veteran cars
and motorcycles.
Osmaston 50 may also be used as appropriate
in gearboxes.

SAE 140 EP Gear Oil
Heavy duty, Bronze compatible gear oil for ‘crash’
boxes, worm drive transmissions, and spiral bevel differential
gears. (For hypoid differentials use Boa 80W-90.) Will not
attack bronze gears and bearings even at temperatures exceeding
100°C. Suitable for many veteran, vintage and early classic
vehicle applications.
API GL3.

Castorene R40 racing oil is a Castor Oil based
blend incorporating synthetic lubricants and additives which
enhance the castor oils of naturally high film strength and
resistance to seizure, this enhancement represents a significant
advance in lubrication containing vegetable oil and minimises
the risk of thickening or lacquer formation.
• Inhibitors derived from aircraft gas
turbine engine technology give stability and oxidation resistance
and both laboratory and racing tests have proved the product.
• Oil thickening and lacquer formation is reduced even
in hot running engines such that the oil can be used for longer
periods than those normally associated with castor-based products.
• Fully soluble in alcohol fuels and ideally suited
for use in both air and liquid cooled racing engines running
on methanol or methanol based fuels.
Note: These are not detergent grades,
and more frequent oil changes are required than with additive
treated mineral oils. Castorene R40 must not be mixed with
mineral oils.
