Castrol R40 - Racing Engine Oils - 1948

Castrol R40 - Racing Engine Oils - 1948

 

Castrol R40 is a castor-based lubricant containing specially prepared additives to prevent rapid deterioration through oxidation. Its superior oiliness over mineral oils, imparted by the chemical structure of its components, gives it a great affinity for hot surfaces and provides excellent load-carrying properties which is an important consideration with highly stressed engines running at peak revolutions.

 

Application

Although Castrol R40 is primarily designed for the racing world, its unique properties can also benefit the private owner interested in really high performance.

When selecting an engine lubricant for sports cars, modified saloons or high performance motorcycles, it must not be assumed that a special oil is always necessary. In the vast majority of cases the well-known, widely available brands of Castrol motor oil are entirely satisfactory for racing, and most modified and tuned production vehicles will operate perfectly well on these. Where special camshafts are fitted though, there may be a case for using Castrol R40 as the small areas in contact will be heavily loaded especially where double valve springs are fitted.

For racing and high speed rallying, however, Castrol R40 does provide the ultimate in lubrication in return for extra cost. If the best possible performance coupled with reliability is the aim, then the remarkable stamina and great film strength of Castrol R40 will provide a valuable 'margin of safety' at ultra high engine speeds and temperatures.

 

Advantages:

  • Unique properties
  • Remarkable stamina and great film strength

 

CAUTION
Never mix Castrol R40 with mineral based oils. It should always be remembered that Castrol R40 will not mix with conventional mineral or synthetic crankcase oil. When changing from one type to the other, Castrol Solvent Flushing Oil must be used in accordance with the recommended changeover procedure.

Castrol Transmax Dex III Multivehicle - Automatic Transmission Fluid - 1713

Castrol Transmax Dex III Multivehicle - Automatic Transmission Fluid - 1713

 

Automatic Transmission Fluid

 

Description

Castrol Transmax Dex III Multivehicle is designed for use in GM automatic transmissions pre 2005 and Ford automatic transmissions built between 1983 and 1996 where Dexron® (II or III) or Mercon are required. This product is approved for use in Allison heavy duty transmissions against TES 389. It is also approved for use in a wide range of european heavy duty automatic transmissions. It may be used in some power steering units. NB: Do not use where MERCON® V, MERCON® SP or DEXRON® VI is required.

 

Advantages

  • Multiple manufacturer approvals make it suitable for wide ranging use.
  • It is specifically formulated for high thermal stability and resistance to oxidation which protects against the formation of deposits and oil thickening prolonging the life of components and lubricant.
  • Optimised friction characteristics provide smooth shifting and efficient power transfer.
  • High viscosity index provides a stable viscosity over a wide temperature range for effective protection of transmissions and operation of power steering units

Castrol TranSynd - Fully Synthetic Automatic Transmission Fluid - 1714

Castrol TranSynd - Fully Synthetic Automatic Transmission Fluid - 1714

 

Applications
Castrol TranSynd can be recommended for all vehicles calling for Dexron III/Mercon or Allison C4 ATF's including bus and refuse vehicles with automatic transmissions.

 

Features / Benefits

  • Excellent thermal and oxidative stability means that the viscosity remains almost constant helping prevent deposits and oil thickening - this extends transmission life and avoids incorrect gear changing.
  • Excellent transmission cleanliness under all conditions permits extended oil drain and decreased servicing.
  • Excellent temperature reduction through reduced friction leads to longer oil and component life and permits extended drain and decreased servicing. Lower power input means fuel savings potential and reduced emissions.
  • Optimised frictional characteristics gives smoother gear changing at all ambient temperatures and load conditions. Constant frictional properties improve driving comfort.
  • Outstanding cold flow properties enables faster oil flow to all critical components (eg torque converter, friction plates, planetary wheels and brake bands) particularly during cold starts. More responsive and comfortable gear change.
  • Minimises 'shift stock' when changing gear.
  • Excellent shear stability properties helps retain full transmission performance over whole oil drain period.
  • Optimal lubrication ensures constant level of comfort during gear changing.
  • Good extreme pressure (EP) and anti-wear performance gives better transmission component protection leading to longer life.
  • Very good seal performance helps avoid oil leakages, reducing repair costs.
  • Free from chlorine and heavy metals for better environmental compatibility - easier waste oil disposal and recyclability.
