Lubricant works

Not подмажешь... This old rule in special degree concerns the car, and in it first of all to engine greasing. Because the highest demands are made to engine oil. Along with the best greasing ability are necessary stability to temperature influences, stability to ageing, ability to act in roles of cooling means and ability to hold a dirt particle in a hover.

Check of level of oil in the engine

Constant check

If you have just got Audi 80 (new or second-hand), it will be better, if you check oil level at each refuelling. If it becomes clear that the engine spends not enough oil it will be possible to increase an interval of the control to every second or even every fourth refuelling.

 PERFORMANCE ORDER

  1. To stop the car on a horizontal platform.
  2. After deenergizing of preliminary heated-up engine to working temperature it is necessary to wait still a minimum five minutes that oil could flow down in the pallet. Even more effectively the control before the first start still the cold engine.
  3. It is necessary to be cautious with the hot engine not to burn to itself a hand.
  4. To extend probe (the index of level of oil), to wipe its pure, not leaving fibres, rag or paper napkin, again to insert against the stop, a few to wait and again to pull out.
  5. On a tip probeа you will see oil level.
  6. If the quantity of oil gets only to the bottom mark, it is necessary to add oils in the engine.

Доливка oils

The difference between the top and bottom mark probeа makes 1 l. Oil level should not fall below the bottom marks. If on a quarter of litre it is less than oil of all, than it is necessary, for the engine it is possible not to be afraid for the present. But if level of oil even more low, 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 the control of pressure of oil.

Too the oil considerable quantity in the engine too is unreasonable. At high turns oil can get through ventilation system картера to combustion chambers. For каталитического neutralizer surplus of oil in the fulfilled gases as is dangerous, as well as unfinished gasoline as can lead to breakage. However at normal level of oil of 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 enough add oils when its level will fall on the bottom mark.
  • At sharp style of driving the oil additive if its level is in the bottom third or a quarter between both marks is recommended. The bolshee quantity of oil can carry out cooling functions is better.

Oil in small amounts is more expensive, than in three- or five-litre canisters. However similar canisters are usually not so convenient for oil addition on the journey. Besides, they take a place in a luggage carrier. For exact dispensing of oil the one-litre canister with a twisting cover more will approach.


For the control of level of oil it is necessary to extend маслоизмерительный probe from a directing tube on an engine left-hand side. Oil level should be between marks max and min, that is in the field of a corrugated surface (on arrows) on a tip probeа. 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 manufacturers can be mixed safely among themselves, as also seasonal oil with the all-weather. This ability to mixing without harmful consequences is the basic requirement of the international norms shown to oils. Though specific properties of certain oil, probably, will undergo easy changes at mixing with other engine oil because each grade of oil possesses own combination of additives. However similar mixing does not render menacing influence on greasing action.

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