How to use Wurth Engine Flush & Change Oil

[vRS Carl]

Ok here's another Tutorial. This is done on a MK2 Skoda Octavia vRS but i would imagine the process is the same or pretty similar for all MK2 Octavia's

Before i start the usual disclaimer

NEITHER I NOR BRISKODA WILL BE HELD RESPONSIBLE IF YOU UNDERTAKE THE PROCESS DETAILED BELOW AND SOMETHING GOES WRONG. YOU DO SO AT YOUR OWN RISK!!

Ok formalities out the way here we go.

You will need the following:

Jack

Axle Stands x2

19mm Socket/Ratchet/Spanner

36mm Socket/Ratchet/Spanner

T25 Torx Bit and Driver

T30 Torx Bit and Driver

6 Litres of Oil (Longlife or standard depending on your servicing regime)

1 Can of Wurth Engine flush (will treat up to 6 Litres of oil)

1 x Oil Filter and Rubber Gasket (come together) Part no. - 06D 115 562

1 x Oil Sump Plug and Captive Seal - Come as one part from Dealer.

Firstly jack the car up and remove the Under tray. This area there are 3 x T30 Torx Screws

This area there are 4 x T25 Torx Screws (same for other side)

Now check that you have the correct size socket/spanner to remove the Oil Filter and Sump Plug. You don't wanna be driving round with engine flush in there all the time

Now check the oil in the engine is at least halfway between min and max on the dipstick then get the engine to Normal Operating temperature.

Once that is done Switch off engine and add the Wurth Engine flush.

Now Start engine and leave running for 10 Mins

Once 10 mins has passed stop engine and get container ready. Undo oil sump plug (beware it may be quite hot!!!) and then catch oil that comes out. I removed the dipstick and oil cap before doing this just so there was no suction at all to hold anything in.

Once all oil out Undo oil Filter and again have container ready to catch the oil.

Whilst container is catching all the the oil remove old filter and gasket. The Gasket has a small tab indicated by the Screwdriver. Ensure that is uppermost (i.e. you can see it) when putting the new gasket in

Next get new gasket coat with fresh clean oil and place into filter holder

Put new filter into holder and reattach to engine. Tighten up just hand tight then 1/4 of a turn.

Now i put 1/2 litre of clean oil through the engine just to flush any remaining cr@p out.

Re-apply oil Sump Plug and tighten up to 30NM or Hand tight then 1/2 turn

Now apply fresh oil. The vRS is supposed to take only 4.7 litres (Check Manual for how much your engine holds) but i filled up till dipstick was indicating as per the pic. Now start the engine let it run for 30 secs then topped up to the same place on the dipstick. I used 5.5 litres in total

Once all topped up run engine for 2 mins check dipstick again and if you have VCDS check for faults ( i had none )

Now refit under tray and lower the car. Reapply dipstick and Oil Cap.

Job done

Will take 45-60mins

Good write up. I read one from a golf and it mentioned something about releasing a nipple in the filter housing to let some more oil out, did you do that? I have some forte flush which i will use soon in an attempt to free the piston rings up a bit and slow oil consumption a little.

[vRS Carl]

You can do that but i didn't i just caught the oil in a bowl.

The nipple will be a bit of a nightmare to put back in due to the long grill in the centre on the Holder

You must have read my mind;)Had to order oil sump plug from garage which i will be collecting tomorrow along with filter,and doing it this weekend.You mentioned Wurth engine flush.What does this actually do as i did not know about it, and can i use it on my diesel?Cheers:thumbup:

[vRS Carl]

Here is a link to the Product i used.

Wurth Engine Flush

AFAIK you can use it on a Diesel Engine BUT i am not 100% so you are better off checking with a Dealer. I bought the Wurth from Caffyn's Skoda in Ashford so ring them and ask as they advertise it for use by them when they do Servicing.

Cheers for that will have a look.

p.s good pictures:thumbup:,helped me a lot.

Good how-to

Now take old oil to recycling centre.

[vRS Carl]

Just checked the Can in the Bin

It says on it:

"For all Petrol and Diesel Engines with or without Catalytic Converter"

So yes you can use it on a Diesel Engine

Very useful write up with great pics, just what I needed, cheers for taking the time:thumbup:

I realise this is a very old topic but I have just come across it.

 

I've heard both side of the argument for using engine flushes with the main concern being about dislodging carbon that is actually helping seat rings etc etc, but this is normally only a concern for vehicles with high mileage or that have never used a flush before. One thing that sticks in my mind that is relevant to all vehicles new or old, is someone saying that when you drain the old oil out you never get it all because of things such as oil cooler etc - fair enough, il go with that.

 

So if you add an engine flush, then by the same token as above, some must remain in the engine with that bit of old oil (which apparently can be up to 0.5 litre).

 

So basically the new oil will be contaminated with this bit of engine flush. By the ratio of engine oil (~5L?) to flush (~250ml usually) this will obviously only be a tiny amount and whether this is enough to potentially cause any harm is up to you decide. Just something else to consider.

 

I should add that when I had my diesel vRS serviced at an independant german specialist they used STP engine flush. As I have seen many high end cars in there (Aston Martin, Ferrari, BMW M3/5, Porsche etc etc) I would like to think they are confident in what they are doing!

The cynic in me thinks they sell the flush (and heavily encourage its use) because it's a good money earner.

[SW_VRS_2012]

Haha quite possibly. The thing is its only around £3 for a bottle so for individual customers thats not really an issue but as you say £3 x 1,000, 10,000, 100,000, 1,000,000 etc customers is a decent chunk.

You shouldn't need the engine flush if you use synthetic and change the oil regularly. Beware of using flush on a higher mileage vehicle as it may loosten crud that can block oil ways. Regular changes are the key to keeping everything clean and clear.

Where did you put the axle stands for holding the car up? Normally when jacking up on the sill, you need a hockey puck with a slot in it. Do you need something similar for the axle stands?

under the front aluminum console bushes either side should be fine and no puck is needed as the console is curved and sits nicely in the axle stand

[FatblokeVRS]

Any chance of a photo??? Would that bit be strong enough on a CR with all the extra weight?

[FatblokeVRS]

Cheers for that. Appreciated.

As mentioned before, Regular oil/filter changes with good quality oil, Should not need engine flush...
