Check of level of oil

When checking level of oil the probe (1) is taken out from the directing tube. Level of oil has to be between marks or in the field of a corrugated surface (arrow) on a probe tip. The amount of the added oil between markings makes 1 l. Measurement can be exact only if the car costs on a horizontal surface.

Constant control

If you just got the Audi A4 (new or second-hand), have to for the sake of safety during each filling of a fuel tank undertake the probe for measurement of level of oil. When you learn that your engine spends very few oil, inspections can be carried out between the second and fourth gas station.


  1. According to instructions of Audi control of level of oil has to be exercised at a temperature of engine of 60 °C that corresponds about 10 min. after start of the cold engine.
  2. To put the car on a horizontal surface.
  3. After switching off of previously heated-up engine to wait at least five minutes in order that all oil flew down in a case.
  4. Be careful with the hot engine, it is possible to burn a hand about the details located around.
  5. Take out the probe, wipe it a pure, not fleecy rag or a paper napkin, again enter against the stop, wait a little and again take out.
  6. On a core you will be able to see oil level.
  7. If the level of lubricant means reaches only the lower point, engine oil needs to be added.

 Council: If you want to keep the exact magazine about an oil consumption your Audi A4, you have to perform measurements always in one place and at the same temperature of oil.

Black color of oil in itself is not a signal to replacement motor oils. Oil again darkens even soon after replacement. The dropping-out dirt and products of attrition remain in a suspension in order that they did not get in the engine.

Having added oils

The difference between the lower and top marking on the probe for measurement of level of oil makes 1 l. Level of oil should not fall below the lower mark. The lack of a quarter of liter of oil is not dangerous yet but if there is no bigger amount of oil and by Audi A4 go in a sharp manner, on turns pressure of oil can fall to dangerous level.

Also excess of oil in the engine is harmful. At high turns it can get through an air vent in the case case to combustion chambers. Excess of oil is also dangerous to the catalytic converter, as well as not burned down gasoline. Consequence: it can melt. But at a normal consumption of oil it is harmless.

Result: oil is recommended to be added when its level is in the lower quarter between two tags of the probe. Do not pour oil above the top tag.

 Council: Oil in a small amount is more expensive, than in 3-, 4-or 5-liter canisters. On the way such packing is most often inconvenient for oil addition. Besides, it takes a lot of place in a luggage carrier. The 1-liter can of engine oil with the screwing-up cover from which you necessarily can add oil in the small portions is convenient.

Whether it is possible to mix oils?

It is possible to mix bravely all grades of oils of any producers, including one-target and multi-purpose oils. This miscibility without harmful consequences is the main requirement of the international standards of oils. Though mixing with other engine oil can affect specific properties of a certain oil as each brand of oil possesses an own combination of additives slightly. But never the lubricant effect is exposed to danger. To the one who adheres to the standards recommended by Audi firm on oils, danger of damage of the engine because of improper oil does not threaten.
