Why it's crucial to use premium gearbox lubricants for the automotive and industrial applications

Total Transmission Gear Premium Oil



When it comes down to the maintenance of vehicles and equipment, lubrication is key, extending the life of components and reducing downtime, but often, gearbox oils can be overlooked, and basic lubricants chosen over premium options.

Vehicle owners should follow their vehicle manufacturers’ OEM recommendation in terms of SAE viscosity and performance levels. By doing this, they will get the best performance oil giving extended life, fuel efficiency and good protection to avoid metal to metal contact.

For modern vehicles, premium oils also known as synthetics are recommended.


Total’s gearbox lubricants range 


Total has developed a wide range of gearbox lubricants for technicians and fleet managers concerned with prolonging the life of their equipment for as long as possible:



Both have the following advantages over basic oils and are available for cars, vans, commercial vehicles, agricultural vehicles and construction machinery:


  • Lower maintenance costs due to extended drain periods
  • Excellent protection against wear and corrosion thanks to their resistance to extreme pressure
  • Less drag and improved fuel consumption, even during cold starts, thanks to their low temperature fluidity
  • Excellent stability in service thanks to their high viscosity index
  • High compatibility with oil filters due to their antifoam properties
  • Improved fuel economy, to help you reduce fuel costs and protect the environment.


TOTAL TRANSMISSION GEAR is a fluid designed for synchronized and non-synchronized gearboxes, mild loaded axles, transfer boxes and all gears requiring MIL-L-2105 or API GL-4 level. It is available in a range of grades and can be used in most vehicles and machinery.


TOTAL TRANSMISSION DUAL has been developed to for synchronized or non-synchronized manual gearboxes, axles and reduction gears. It is available for use in a wide variety of makes and models.




How to choose an industrial gearbox lubricant 


Before you choose between a traditional or premium gearbox lubricant, it’s worth assessing your gearbox and its operating conditions:


  • The gearbox’s dimensions, the materials used in its construction, gear ratio and casing type
  • The stresses the gearbox is under, including load, vibration and shock
  • Service oil temperature, graded from very low (0-19°C), to moderate (20-80°C), hot (+80°C) and extreme (+120°C)
  • The environment the gearbox is used in – dusty, cold or humid (a traditional oil would be best to use and change it more frequently)
  • Whether the lubricant itself must be biodegradable, food-grade or non-staining
  • How frequently the oil will be able to be changed as part of its maintenance routine.

The benefits of high-quality industrial gearbox oils

Once you have answers to the above, you can properly assess your needs against the benefits of premium gearbox oil.


  • The larger or smaller the gearbox, the better suited to premium oil it will be, due to the larger pressures and strains inflicted on the drivetrain.
  • If the gearbox is under considerable stress throughout most of its operating life – if it’s a component of quarrying machinery, for example – then premium gearbox oils will help prevent wear and reduce pressure on components. This can increase the gearbox’s lifespan.
  • The higher or lower the service temperature, the greater the need for a premium lubricant that can operate under very low, high or extreme heat. A good rule of thumb is that if the operating temperature of the gearbox is below - 5°C or above 80°C, then a premium oil is a sound choice.
  • If operating in particularly humid, dusty or icy environments, then a premium oil can save money by preventing corrosion and time, thanks to the fluid’s increased service life.
  • Premium gearbox oils can have biodegradable, food-grade or non-staining properties, useful for businesses concerned with their environmental impact, or that work close to foodstuffs.
  • Synthetic oils need to be replaced far less often than traditional oils, so are perfect for businesses that don’t have maintenance capacity or want to reduce their maintenance costs without sacrificing safety.
  • Many synthetics have anti-foaming properties – foaming in lubricants reduces their function.
  • Premium oils increase overall fuel economy, saving money.
  • All the above do require a higher initial cost compared to basic oils, but this is more than made up by the maintenance and fuel economy savings in the long run.

Total’s lubricants protect gearboxes, extending their lifespan and saving money and time in kind. For more information on which is best-suited to your business, feel free to contact our team for information and advice.
