Audi Q5: Engine oil consumption

Audi Q5 Type 8R (2008 - 2017) Owner's Manual / Operating instructions / Checking and Filling / Engine oil consumption

The engine in your vehicle depends on an adequate amount of oil to lubricate and cool alt of its moving parts.

In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with a specified break-in period consume more oil during the break-in period than they consume after oil consumption has stabilized.

Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM (revolutions per minute) at which the engine is operated, the ambient temperature and road conditions. Further factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. As any engine is subject to wear as mileage builds up, the oil consumption may increase over time until replacement of worn components may become necessary.

With all these variables coming into play, no standard rate of oil consumption can be established or specified. There is no alternative to regular and frequent checking of the oil level, see Note.

If the yellow engine oil level warning symbol in the instrument cluster lights up, you should check the oil level as soon as possible. Top off the oil at your earliest convenience.

WARNING

Before you check anything in the engine compartment, always read and heed all WARNINGS.

Note

Driving with an insufficient oil level is likely to cause severe damage to the engine.

Tips

  • The oil pressure warning display is not an indicator of the oil level. Do not rely on it. Instead, check the oil level in your engine at regular intervals, preferably each time you refuel, and always before going on a long trip.
  • If you have the impression your engine consumes excessive amounts of oil, we recommend that you consult an authorized Audi dealer to have the cause of your concern properly diagnosed. Keep in mind that the accurate measurement of oil consumption requires great care and may take some time.

    An authorized Audi dealer has instructions about how to measure oil consumption accurately.
