CASTROL SMX - S
  • Castrol SMX-S can be recommended for most manual transmissions where API GL1-4 lubricants are required. It has been used successfully as a problem solver in the manual transmissions of a number of manufacturers.
  • Excellent synchroniser performance giving extended synchroniser life and shift comfort.
  • Exceptional cold flow properties giving smoother gear shift at low temperatures.
  • High shear stability giving a constant viscosity during oil life and noise reduction.
  • Excellent thermal and oxidative stability for transmission cleanliness and longer oil life.
  • Excellent temperature reduction through reduced friction.
  • Good seal compatibility helping to avoid oil leakages and repair costs.
  • Free from chlorine and heavy metals giving better environmental compatibility.
  • Stringent performance specifications including SAE 75W-85
  • API GL1-4

SMX-S

CASTROL TAF-X 
  • SAE 75W/90 is a fully synthetic multi-grade gear oil gives to ensure extra protection at extreme low and high operating temperatures.
  • It is formulated with specially selected additives to combine extreme pressure qualities with synchro-cone compatibility.
  • It is designed to help improve cold weather gear selection and keep transmission noise levels to a minimum at high operating temperatures.
  • Castrol TAF-X is recommended for use in manual gearboxes, transaxles, transfer boxes and final drives where an API GL4 lubricant is specified.

TAF-X 75w90

SAF-XJ

CASTROL SAF-XJ   
  • Castrol SAF-XJ is a fully synthetic SAE 75W-140 hypoid gear oil formulated for use in both conventional and limited slip differentials.
    Whilst being suitable for all applications where a lubricant of this quality is specified it is specially formulated for use in limited slip differentials fitted to Japanese vehicles requiring an SAE 75W-140 Extreme Pressure Gear Oil. Castrol SAF-XJ has additionally demonstrated outstanding performance in competition vehicles employing limited slip differentials. 
  • Castrol SAF-XJ is also specifically designed for BMW differentials including the Z3 limited slip differential.

 

 

 

SAF-XJ

 

CASTROL Syntrax Universal
  • SAE 75W/90 is a part synthetic multi-grade gear oil which employs advanced technology additives to ensure extra protection at extreme low and high operating temperatures. 
  • Tested and proven, this SAE 75W/90 multi-grade gear oil is synchromesh compatible and designed with a low chlorine formulation to allow environmentally responsible disposal of used oil. 
  • It meets the need for a 'universal' gear oil which can be used in automotive manual gearboxes, transaxles, transfer boxes and final drives where stringent performance specifications including API GL3, GL4 or GL5 must be met.

Castrol Hypoy LS 90

  • Castrol Hypoy LS is a mineral oil based SAE 90 extreme pressure gear lubricant designed to cope with the special friction characteristics of limited slip differentials and associated hypoid gears.  
  • It has been particularly developed for use in limited slip rear axles fitted to high performance cars.
  • This oil should be used where a 90 grade is recommended by manufacturers.
  • A full extreme pressure oil for limited slip differentials fitted to all types of vehicle. (Aston Martin DB7)
  • SAE90
  • API Service GL5US 
  • Military MIL-L-2105B
  • 20 ltrs drums

 

 

 

Hypoy LS90

Castrol B373 Dif Oil
  • Castrol Product B373 is a mineral based extreme pressure gear oil which combines limited slip performance with excellent load carrying ability.
  • Castrol Product B373 is particularly suitable for use in limited slip final drives fitted to competition vehicles.
  • A full extreme pressure oil for limited slip differentials in racing and rally cars. 
  • Not suitable for normal road use. 
  • API Service Level GL6+

 

 

 

B373

CASTROL Classic D140 (Castrol D)
  • Monograde 'straight' high quality oil for most types of gears, including helical, spur, bevel and worm.
  • It must not be used for hypoid gears requiring extreme pressure oils.
  • 1 Ltr Bottle or Case

 

 

 

D140

CASTROL Classic ST90  (Castrol ST)
  • Castrol ST 90 gear oil is formulated with high quality mineral oils to SAE 90. Castrol ST 90 is formulated with sufficient anti-oxidant and anti-wear additives to ensure that the oil is able to withstand the oxidising conditions which will be present in the gearbox during service and to ensure that the gear teeth are protected against wear should the hydrodynamic fail under extreme load.
  • Castrol ST 90 is suitable for the lubrication of most types of gear including helical, spur, bevel and worm, but must not be used for hypoid gears which require special extreme pressure lubricants. Castrol ST 90 is ideal in commercial vehicle gearboxes and is recommended by many commercial vehicle manufacturers for this purpose.
  • SAE90

Castrol Classic ST90

CASTROL Classic EP90
  • An extreme pressure suitable for non-hypoid and hypoid differentials and some manual transmissions. 
  • API GL4 specification.

 

 

Classic EP 90

CASTROL Classic EP140
  • For manual transmissions and some Hypoid differentials where an Extreme Pressure SAE140 gear oil is recommended.

 

 

Classic EP140

Castrol TQ Dexron III

Castrol ATF TQ DIII is an automatic transmission fluid designed to meet the requirements of Dexron® IIIH, Ford Mercon® and Allison C4 specifications. 

 

It is suitable for use in all automatic transmissions where Dexron® III performance is specified.  It is fully compatible with earlier Dexron® and Mercon® type fluids and may be used for topping up or completely replacing. Castrol ATF TQ DIII is dyed red to distinguish it from engine oils should leakage occur. Castrol ATF TQ DIII can also be used in most powershift transmissions, power steering and hydraulic units. Excellent thermal and oxidative stability Excellent cleanliness extending component life Reduced oil thickening, maintaining transmission efficiency   Good low temperature fluidity Good gear shift quality at low temperatures    Friction durability Maintains transmission performance  Good wear control Maintains equipment life    Protect against rust and corrosion Maintains equipment life    Compatible with seals Protects against leaks    Meets the requirements of Dexron® IIIH Ford Mercon® License number M051103   Allison C4, MB 236.5, MAN 339F, ZF TE-ML 04D, 14A, 17C, Voith 55.6335

Castrol TQ-D

Castrol TQ-D is an automatic transmission fluid meeting the requirements of General Motors (Europe). Although now no longer recognised by the General Motors Licensing Authorities, Castrol TQ-D continues to offer the quality level required by General Motors in Europe.

  • Additionally, those manufacturers who traditionally use 'Dexron' approved products i.e. Mercedes Benz, Voith, ZF etc., continue to specify this performance level although not where General Motors Dexron® IIE fluids are stipulated. 

  • If Dexron® IIE is specified then Castrol TQ Dexron® IIE should be used. 

  • Castrol TQ-D continues to meet the Ford specifications ESP-M2C-166H and SQM-2C-9010-A and is the prime recommendation for the power steering systems of commercial vehicles and coaches.
