Oil consumption

[Breezey]

Hi guys,

Just wondering how much oil your S3s are using as mine seems to have used about half a litre if 5w-30 edge in 5000 miles and there arnt any leaks that I see is this normal?

Drop the 5w30 and change to 5w40 or 10w40. Do an oil change every 5-8k and you'll find you'll never need to top up

 

[Reesy]

Change my oil every 5-7k and that is the only time I ever need to take the oil cap off, it doesn't seem to use any!

i use 5W40 quantum platinum oil from Audi and it never seems to use up any of it

Cheers looks like I shouldn't trust the castrol website that recommends 5-30


Edit: worth using an engine flush or no? Not used them in the passed but I know some of you replace the pickup pipes don't know if this would help, sump off job isn't it to replace the pickup?

1/2 ltr in 5k is fairly normal... 5w30 is specced as a longlife oil grade typically but if you can do it yourself then use 5w40 and drop it every 5/6k...

I did use engine flush when I first got my car after I discovered it was on AVS... I used Wynns stuff... no idea if it did any good tbh but I now just change my oil every 5/6k so its not really an issue any more..

Pickup pipe is a worthwhile investment for just over a tenner... does mean dropping the sump and there is a guide on here somewhere... only use the VAG sealant though when you put it back on as this stuff just doesn't leak..

I flush mine every 6-7 k with wynns and use shell helix ultra 10-40 never had a problem used around half a litre in that time..

Interestingly, I've been using 10-40 semi synth in mine for yonks, and it tends to get through a fair bit, and needs a top up every 1000-1500 miles.

Switched to Quantum platinum, which I think is 5-30 at the last change, and 1500 miles later it's not moved on the dipstick at all!

a vote for 5W40, last much longer

How long does a flush take?

How long does a flush take?

20 mins or so normally on a mixture of normal and fast idle.

thanks welly, if I poured it in before a 20 minutes drive would that be ok?

No you dont drive with it in usually fast idle around 2000rpm for 15 mins

 

[finesse]

ok thanks Dave

 

[superkarl]

i left mine on tick over for 15 mins with it in, as recommended on the bottle.

 

[Prawn]

what's the problem with driving with it in guys? really?

I tend to drive into town, which warms the car up. Buy the engine flush at camberly auto factors, pour it in at the carpark there, then drive 5 miles home, and leave it ticking over whilst I get all the tools and oil drainer ready

 

[finesse]

cool, getting the sump cleaned so may aswell do it

good point i dont actually know, i just did what the bottle said.
ended up finding tiny hard bits in the oil afterwards mind, thats when the sump came off

 

[s3dave]

Well it does warn you not to rev over 2k or something, i would think the cleaning agents in it might not lubricate things properly under load..?

 

[Breezey]

Thanks guys, most of you using quantum stuff from audi then?

When i run the engine flush i put it in the car and drive to my garage, a 5 minute drive, never go above as someone said above 2k RPM not sure what that stuff does to an engine under load so i drive like my nan on a sunday, then leave to idle and that gives you time for a brew and a cig.
