Quick oil question

[saf]

Hi guys,

Just having brakes changed tomorrow morning and while its in the garage need to get an oil change done.

Not got much time so just wanted to know whats best for a high miler S4 oild wise.

Im running approx between 330 and 350 on a stage 2 + MRC remapped car. HAs 120,000 miles on it, is a Vreg face lift model.

Should i use the oil the cars used all its life . Its had audi main dealer long life service, using long life 3 oil which is 5w 30.

Ive been told this is not the best oil for the engine and i should revert to 0w 40 mobile synthetic. Is this the better option.

Just for information, i do a lot or town driving. So whats best?

Thanks guys.

I use mobil 1 0w 40

[Dippy]

Or any other decent fully synthetic brand. 0W40 or 5W40.

Cheers

Does any one know method of changing oil

Im gonna get oil filter changed. gonna pick one up from audi before 5 today.

Im not sure about getting the engine flushed however. Do I have to flush the oil out, or just have it drained. If so what flushing agent has to be used?

Cheers for the replies guys.

Just remove the sump plug and let the oil drain out, better when the oil is warm. Remove the filter and fit new one, put sump plug back in and fill with new oil.

Change every 5k miles and no need to flush

Castrol EDGE SPORT fully synthetic 0W40 is what I use - pretty good too (equivalent to the Mobil 1 in quality and price - about £12 per litre)

Valvoline VR1 5W/50 Fully Synthetic

thanks guys

I ended up getting the mobile 0w 40 fully synthetic.

Cost me 23 quid for 4 litres. so all in all 46 quid for 8 litres. should leave me with a litre and a half for top up should i need it.

Thanks for all the advice guys.

Good price - are you willing to disclose where from?

[saf]

yes sure.

Theres tonnes there.

Costco wholesale. You need a membership card though. youy can buy as little or as many as desired.

Theres one in north london edmonton. very close to east london chingford area.

If anyone would like to stock up let me know. ill meet you there and you can come in with me and use my membership to get some.

[Dippy]

Probably too late now, but the sump plug is a DISPOSABLE item which should be replaced each time. I guess it's not a catastrophe to reuse it, but for the cost (less than a quid IIRC) it makes sense to replace it.

[saf]

Just got back from oil change.

You guessed right dippy. It was reused. Whats the downside in reusing it?

Where can i get one from for next time?

Changing from 5w 30 to 0w 40, it might just be me, but the car definitely seems quicker and more economical. mpg was holding at about 17 ish local driving rather than 15 ish.
Any thoughts?



Main dealers?

[SimonS4MTM]

I have never changed my sump plug, and I have done around 18 oil changes on both my S4's.

The only down side is that it may start to leak, but if it does not, then there is no need to change it.

[S4TAN]

If you really want to change your sump plug get a magnetic one - it helps take metallic particles out of the engine oil (ECS-tuning sell these)

[saf]

nice one. seems a good idea.

im safe with my sump then.

How many litres of oil should my audi take?

it took 6.5 litres.

that about right?
