Lubricant works

You will not oil... This old rule in special degree belongs to the car, and in it first of all to engine greasing. Because the highest requirements are imposed to engine oil. Along with the best greasing ability resistance to temperature influences, resistance to aging, ability to act as the cooling means and ability to keep dirt particles in a hover are necessary.

Check of level of oil in the engine

Continuous check

If you just got Audi 80 (new or second-hand), it will be better if you check oil level during each filling. If it becomes clear that the engine spends very few oil, it will be possible to increase a control interval to every second or even every fourth gas station.


  1. To stop the car on a horizontal platform.
  2. After switching off of the engine, previously heated-up up to the working temperature, it is necessary to wait at least five more minutes that oil could flow down in the pallet. Still effective control before the first start still the cold engine.
  3. It is necessary to be careful with the hot engine not to burn to itself a hand.
  4. To extend the probe (the index of level of oil), to wipe its pure, not leaving fibers, a rag or a paper napkin, again to insert against the stop, to wait a little and again to pull out.
  5. On a probe tip you will see oil level.
  6. If the amount of oil reaches only the lower mark, it is necessary to add oils to the engine.

Dolivka of oil

The difference between the top and lower mark of the probe makes 1 l. Level of oil should not fall below the lower marking. If oil of everything is quarter liters less, than it is necessary, for the engine it is possible not to be afraid for the present. But if the level of oil is even lower, and besides the car operate in a sharp manner, pressure of oil can fall to dangerous level, on what immediately specifies a precautionary buzzer of control of pressure of oil.

Too large amount of oil in the engine too is unreasonable. At high turns oil can get through system of ventilation of a case to combustion chambers. Excess of oil in exhaust gases is also dangerous to catalytic converter, as well as unfinished gasoline as can lead to breakage. However at the normal level of oil similar danger is not present.

At what level of oil it is necessary to add it – depends on style of driving:

  • At moderate style of driving will be to add enough oils when its level falls by the lower mark.
  • At sharp style of driving the oil additive if its level is in the lower third or a quarter between both marks is recommended. The bigger amount of oil can carry out the cooling functions better.

Oil in small amounts is more expensive, than in three - or 5 liter canisters. However similar canisters are usually not really convenient for oil addition on the way. Besides, they take a place in a luggage carrier. The one-liter canister with the twisting cover will be suitable for exact dispensing of oil more.

For control of level of oil it is necessary to extend the masloizmeritelny probe from the directing tube on the left side of the engine. Level of oil has to be between marks of max and min, that is in the field of a corrugated surface (on shooters) on a probe tip. The added quantity between both marks makes 1 l. Measurement will be exact only when the car costs on a horizontal surface.

Whether it is possible to mix various types of oil?

Grades of oil of all producers can be mixed safely among themselves, also and seasonal oil with the all-weather. This ability to mixing without harmful consequences is the main requirement of the international standards shown to oils. Though specific properties of a certain oil, perhaps, will undergo easy changes when mixing with other engine oil because each grade of oil possesses own combination of additives. However has no the menacing impact on the similar mixing greasing action.

Who adheres to norms of the oils specified by Audi can not be afraid that unusable mix will lead to damage of the engine.
