gas mileage AUDI RS5 CABRIOLET 2015 Owners Manual

198 Checking and filling
Using the proper engine oil is important for
the functionality and service life of the en­
gine. Your engine was factory-filled with a
high-quality oil which can usually be used
throughout the entire year.
0 Note
Your Limited New Vehicle Warranty does
not cover damage or malfunctions due to
failure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet.
- Use only a high quality engine oil that ex­
pressly complies with the Audi oil quality
standard specified for your vehicle's en­
gine . Using any other oil can cause seri­
ous engine damage.
- Do not mix any lubricants or other addi­
tives into the engine oil. Doing so can
cause engine damage.
If you need to add oil and there is none
available that meets the Audi oil quality
standard your engine requires, you may
add a total of no more than 0.5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- Vehicles with gasoline engine: ACEA A3
or API SM with a viscosity grade of
SAE 0W-30, SAE SW-30 or SAE SW-40.
- For more information about engine oil
that has been approved for your vehicle, please contact either your authorized
Audi dealer or Audi Customer Relations
at 1 (800) 822-2834 or visit our web site

Engine oil consumption
The engine in your vehicle depends on an ade ­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of internal engine components, all in­
ternal 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 (see
¢ page 179) consume more oil during the
break -in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption 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 fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion 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 es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­ el, see
Note.
If
the yellow engine oil level warning symbol
El in the instrument cluster lights up, you
should check the oil level as soon as possible
¢ page 199. Top off the oil at your earliest
convenience
¢ page 199.
A WARNING
--
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
& in Working in the engine
compartment on page 195.
{(D Note
Driving with an insufficient oil level is like­
ly to cause severe damage to the engine .
(D 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, pref­ erably each time you refuel, and always
before going on a long trip. .,.
