Hi all,

I can see the sump at the back of the engine with a drain plug in the
centre, but I can also
see an oil pan (?)  with a drain plug at the front of the engine (this
is where the oil filter is).

Do both have to be drained for an oil change, or does the oil from the
front pan drain into the sump when stationary?

thanks

There's only one you need to use. The one in the oil pan.
Use synthetic oil and change the filter too. Both will last for 30.000 Km.
The other one is the gearbox and needs no new oil.
Those are factory advises which I think are just fine. On my 2.6 this has
worked well for over 10 years now.
Many people in this group however change oil weekly or so it seems.

Thanks.  The front oil pan looks a little small to be holding 5 litres
of oil or whatever
the capacity is.  There doesn't seem to be a Haynes manual for this
engine.

I take your point about synthetic oil, but having only had the car for
just over a year
and not knowing what was used before, that might be a bit risky.  At
almost 200K
miles, I don't want to end up with oil leaks.

having just oil/filter changed my 2.4 V6 and confirm it is the front plug
near the filter. My engine held 6 litres inc oil filter.

I used Castrol Magnatec 5W30 from Halfords. This magnatec states it leaves a
oil on surfaces when the vehicle is left standing for a few days. Mine
stands from Friday evening to Monday morning so I thought to give it a try.

It's the front ne all right. And the 5 litres (exactly) are not hold in the
pan; it's not a dry sump!
It's also not true that thinner oil leaks easy. All oil will leak when the
seals are gone.
The pressure ( 5 Bar) is the same at all oils.

I see what you mean - the oil dipstick is at a point back a bit from
the pan.

I've heard that switching to synthetic after using regular dino oil may
accelerate seals going south.  Perhaps semi-synthetic would be a safer
compromise?

The ribbed pan with the drain plug is only the sump cover, the oil level is
over the gasket.

You are correct Haynes dont cover the V6 engines, i have got a german manual
covering all models.

I am running my A4 2.8 on a similar regime. 19,000 mile oil changes with
longlife oil. It has been run like this from new and I am at 94,000miles. I
have always been a concerned about it and have worried about engine life
servicing this way. Can you elaborate a little the oil you use and mileage
etc.

Sorry for going a little off topic to the OP but I am interested in peoples
long term experience of extended oil drain intervals.

Thanks Richard

It maybe a 2.6 12v or a  2.8 12v or 30v, they are all pretty much bullet
proof engines, best oil to use is the VAG long life stuff, Castrol SLX is
the brand name, look for the VAG markings.

I had a 2.6 12v and sold it a year ago with 170k miles on the clock, and it
was still going perfect.

It's horses for courses, the Americans change their oil every 2k miles or so
it seems, and we in the UK change it when the handbook tells us, or the car
itself lets us know.

I change mine, approx every 10k miles, or 20k depends on my mood, If I use
cheap oil etc.

Castrol SLX for long life, Mobil 1, Syntec etc if you change every 10k :)

Remember though, long life is really only beneficial if you do mostly
motorway miles, if you potter round town, lots of stop starts, then use a
good quality cheaper oil and change it more often.

Thanks for the info.

Mine is the 2.8 30v and I do use Castrol SLX Longlife II. The car is setup
for AVS so the car tells me when I need an oil change but I always seem to
get about 19,000 miles. I don't hammer the car and I do mainly longish
journeys.

Its good to hear your engine was ok after 170K miles. I am sure it would
have started to show problems by then.

My engine does leak a little oil from one of the cam seal adjuster but this
is 'normal' for these engines. I may get it fixed but its hardly a problem
at the moment. There is however a lot of valve clatter starting from a cold
start (overnight)  for the first few minutes but I put this down to
hydraulic lifters and an oil change made no difference. I also read a tsb
saying it was normal if it disappeared within a few minutes. Other than that
the engine seems as smooth and powerful as it ever did.

FWIW my 2002 1.8T quattro is now on 130k and gets serviced on AVS and this
equates to 30k mile services, which is unbelievable, that's all motorway
miles.

I also have a slight cam seal leak that is common as hell on these cars, but
it does not bother me, and I only keep the car untill 150-170k miles, and I
expect this one to last just as long, I always buy quattro.

I lose around 5k on my trade-in when I come to change it, which is not bad
for 3 years of trouble free motoring, just had another MOT and it flew
through, as all my Audis have done :)

All Audis sound like diesels first thing in the morning, don't worry about
it, just enjoy driving it hehe

Pottering around town is basically all the missus does with this car.
It probably hasn't covered more than 1500 miles in the fourteen months
we've had it!

I'm not R@l :)

But yeah, we don't change oil in the UK like you guys do.

Oh and it's not every 30k kilometers, it's miles, that's even further :)

Nah, it's the audi standard for AVS servicing, it works out how many miles
and how worn the oil is, speed etc, then caculates when the service is due,
this can equate to 20-30k miles

VSAudi Variable Servicing - AVS

It is now over twelve months since Audi introduced its revolutionary Audi
Variable Servicing (AVS) programme to the market.

As a follow-up to this industry first, we thought we would review and
highlight some key milestones.

·        AVS is not an extended service programme, unlike some of our
competitors, both oil technology and engine technologies have been
re-engineered to deliver genuine savings and environmental benefits.

·        Provided correct AVS oil is utilised then driving characteristics
typical journey cycles, will impact on vehicle downtime, service costs, fuel
savings, environmental emissions and waste oil/filter disposals, AVS
produces clear savings in these areas.

·         AVS offers customer choice as a customer can choose either the
Fixed Service Intervals or AVS option (although we cannot think of any good
reason to stay on Fixed Service Intervals, even under shorter urban cycles).

Service intervals are based on the following criteria:

     Minimum interval
    9000 miles irrespective of time

     Petrol engines maximum 19000 miles or two years

     Diesel 4 cylinder TDI maximum 30000 miles or two years

     Diesel 6 cylinder TDI maximum
    22000 miles or two years

Audi has carried out internal survey of all vehicles used by its staff both
field based and head office. The summary results of wave one 2000 are shown
below, together with further corporate industry, end user independent
results and customer comments.

Customers Delighted with AVS Performance

As the Audi Variable Servicing programme comes to the end of its first year,
customers are beginning to relay back some of the stunning results that the
revolutionary system has provided.

            AUDI CORPORATE SALES

            WHERE BUSINESS IS GOING

            01908 601977

Michelin Tyres have taken up the AVS programme on the Audis on their fleet
of over 300 cars, run through PHH Vehicle Management, and have seen some
remarkable results. Mr John Wadeson of Michelin has been delighted with the
AVS programme so far. An example of its success is one of Michelin's Audi A4
TDI (90bhp) which came in for its first service at 25,600 miles at HR Owen
Audi, London.

I suppose it is a bit of a waste, but it's done its miles (almost 200K)
and needs a rest.
Thankfully she loves the car.  The nagging has ended!
