Why use synthetic aircraft engine lubricants.

Why should you use synthetic aircraft engine lubricants?

When they use synthetic aircraft engine lubricants operators not only extend the operating life of equipment but also reduce operating costs and increase safety.

Since the 1940’s engineers have noted the many advantages of using synthetic aircraft engine lubricants. Initially the value was found in the 2nd World War where icy winter conditions and increasing operating altitudes meant that lubricants’ temperature stability was becoming increasingly important.

There are many advantages to using synthetic aircraft engine lubricants.

The technical advantages when you use synthetic aircraft engine lubricants include:
  • Improved oxidation resistance  of the engine lubrication
  • Better Viscosity stability across wide temperature ranges 
  • Better chemical and shear stability 
  • Decreased evaporative loss 
  • Resistance to oxidation, thermal breakdown, and oil sludge problems 
  • Extended oil change intervals, with the environmental benefit
  •  Improved fuel economy in certain engine configurations 
  • Better lubrication during extreme cold starts and operation 
  • Extended engine life 
  • Superior protection against "ash" and other deposit formation in engine hot spots (in particular in turbochargers and superchargers) for less oil burnoff and reduced chances of clogging oil passageway
  • Increased horsepower and torque due to reduced drag 
  • Improved Fuel Economy

Important properties of synthetic aircraft engine lubricants used in the engine.

Motor oil performs a number of functions in the engine: lubrication, cooling, cleaning, sealing, corrosion protection, noise reduction and propeller operation. The most important function being lubrication: Without engine oil all moving parts of the engine would be in direct contact and wear out very rapidly. Oil forms a layer between the parts and reduces friction.

In order to lubricate adequately, oil must be able to withstand high temperatures, pressure and shearing loads. For pilots the most important property of synthetic aircraft engine lubricants is viscosity, its readiness to flow under different temperatures.

During a cold start in wintertime, oil will be thicker than during a warm start in summertime. In both cases it is important that pressure is attained within 30 seconds after start to prevent any damage. At the same time at higher altitudes temperatures drop.

With many aircraft engines fitted with turbo chargers thermal stability and resistance to oxidation of synthetic aircraft engine lubricants makes them preferable over regular mineral motor oils.Regular crude engine oil tends to oxidise at the high temperatures encountered in exhaust gas driven turbos.

There's no doubt that high quality synthetic aircraft engine lubricants offer many benefits. To find out more about the advantages  contact Habot Oil, a specialised synthetic lubricants supplier of top quality synthetic aircraft engine lubricants.
