Oil consumption

[Grazer_skredge]

Hi

Just wondering what the expected oil consumption is with the RS4s.

Just topped mine up with a litre after almost 5k miles.

Be interested to know the average expected consumption on these engines.

thanks

It really does depend! Some use more than others, the good thing is there wasnt a correlation between this and RR results, when we last all met up...

I use about the same.. probably all been burnt and fired out the back or is stuck to the valves, but she does drink!

Mine drank similar amounts up to about 20,000 miles. It's now stopped completely.

just covered 1200 miles and does not require a top up, (21k miles)

Having owned my RS4 for well over 2 years now, the need for a top up is very intermittent. I believe it is down to driving styles, the more the engine lives in the red the more oil it consumes, any one else noticed this?

I wonder if remapping/SW variation have an greater effect on oil consumption.

Mine uses nowt - so far.
Believe it may be dependant on the engines early life.
From a bike background - thrash it from new and it produces more power but uses more oil (and dies earlier) - treat it nice, bed it in and it'll last longer but be down on power (but will use less oil).
As the RS4 engine is in quite a high state of tune from new - would think same applies.

2008 cab, 7k mi, looks like consumption is about .25 qt per 1500 miles.

Oil on dipstick looks really clean.

Our 2008 a4 2.0t fsi eats about a quart per 1000 mi.
Dark exhaust tips and a puff of black smoke at fill thottle.

Mine usually needs a litre top up every 3-5k miles or put it another way, a top up inbetween 5k oil changes.

I haven't found this to be the case. I've done several track days and they've had little or no effect on consumption. Can't really see how s/w would effect it either.....

Interestingly, buy yourself a light piston engined aircraft & you'll fine the break-in procedure is quite different. They run the engine hard at different loads from the outset to seat everything in, rather than going easy.

Yes I agree, but how would it be explained that 1 car uses more oil than another, there most be a variable, I think Aidenjaye is right there. At the moment my car is 1000 miles into a service and I have used nearly a 0.5Lt of oil, 2 track days have been done in that 1000 mile gap, but where as before I would not have used that much oil. I will double check when I get back into my car.

Yes, it is curious.

As I'm sure you know, engine manufacturers build high volumes of the same engine and still find that what appear to be identical units still manage to produce different outputs when dyno tested. From memory I think Porsche's output tolerance in the '80s was about +10%. Any engine producing more than that was stripped & rebuilt. Under performance was not accepted at all. I guess the same can happen with oil consumption..... They are all different. (that's why I treat mine nicely!)

Yep, funnily when MRC removed my Inlet manifold, they found it to be different to the other B7 RS5s they had worked on. The early RS4 inlet manifolds had plastic rings around the inlet trumpets of the manifold later ons did not, so that is proof that the engines are slightly different over the B7 RS4 lifespan. however I doubt this would effect oil consuption.

That is interesting. Do you know the production date for your car?

I wonder if the part numbers are different.

Good point

On another forum (cannot find the link right now), the same point has been made - proper running in results is lesser oil consumption, better fuel consumption and without the other dreaded side effect...

March 06 is reg date, will find out production date. this is the Inlet manifold with plastic inserts.
