Octavia VRS recommended oil and change interval

[ventmore]

Hey guys. Was just wondering what oil you guys used in your VRS, and how often you recommend changing it. Should I just wait until the service intervals or should I change it in between?

Cheers

With the octy vrs, it depends if you have it set for fixed or variable servicing.
Fixed is every 10000 miles or 12 months. If on fixed, you have to use VW 505.01 spec oil.

Variable, the car tells you when it wants a service. If on variable, you have to use VW 506.01 spec oil i.e. Castrol Longlife 2. It's probably the most expensive oil you'll find

You can tell whether the car is fixed or on variable by looking at the sticker in your service manual or under the carpet in the boot (I think).

GQ0=fixed, GQ1=variable.

Do a search, there have been loads of posts with your kind of question

Its the only car i've had that the oil is still clear after 4500 miles!

IMHO. You can't beat Mobil 1. I use Mobil 1 0W 40 and change the oil myself every 6000 miles and at every QG1 service.

Thanks guys...I did a quick search but couldn't seem to find what I was looking for...probably just me being thick

@DGW
There was a reply from you which seemed very informative, but seems to have disappeared...

I do around 15,000 miles per year. Is it best to stay on variable servicing with the benefit of better oil, or change to fixed with more frequent services?
Just want to make sure I'm treating my new baby right.

@Andrew
I don't really understand oils, but tfboy said that variable required that you MUST use VW 506.01 spec oil. Is Mobil 1 0W 40 of this spec?

Mobil1 0W40 is not VW approved for long life servicing intervals.

Sorry to keep going on, but have additional related question...

I have always had an oil flush and filter change when I have had the oil changed in my other cars. Is this recommended or not?

Sorry if these seem like daft questions, but I'm not very mechanical. I drive cars, I pay other people to fix them...

The 1.8T engine is designed to have oil change intervals of up to 30,000km IF the appropriate LongLife oil is used. An oil flush isn't recommended but a filter change is specified when the oil is changed. The 1.9 PD (diesel) engine in the Octavia and Superb is designed to have oil change intervals of up to 50,000km - and diesels have in the past needed oil changes twice as often as petrol engines. Get you dealer to explain variable service intervals to you and/or read the numerous threads here on the subject. If you feel uncomfortable with variable servicing, opt for fixed service intervals. LongLife oils are 'clever' but cost a lot.

Try a search on e-bay for "SLX" i got my vw503 longlife oil for £22.50...... £7.50 P&P...........not bad for oil costing near £60

Oil flushes are a bad plan.

In any case most synthetic oils contain no wax or resins, and hence provided the servicing interval is adhered to they shouldn't get particularly gloopy in the first place.

You are quite right, it is not recommended by VW for long life servicing. Sorry to mislead anyone, it is my opinion only.

Castrol RS 0W 40 all the way! Well every 6K that is.

I use Castrol RS on all my race bikes, and when i ride them i ride them hard and last time i stripped the engine out my YZ450F i couldn't see any sign of were, Castrol RS 0W 40 all the way!

I understand that it is an excellent oil but which VW specs does it meet?

Interesting

Just had my 1st Variable service (18.5k miles in 11.5 months) and on the bill was a charge for... engine flush.

So assuming a flush isn't recommended for synthetic oils, that's me officially confused!

Should I be getting worried or do you think this is this some specific VW flush for their long life oil?

The servicing manual I have for my 2001 Octavia vRS states that the oil used on variable servicing (GQ1) is VW 503 00.
VW 506 01 is used for ATD diesel engines. VW 506 00 is used on all other diesels.

It doesn't state what oil is used on fixed (GQ2) servicings.

Don't know wether they have changed their minds on the spec of oil in the last few years or not, but that conflicts with the advice given earlier.

If you have or know someone with VAG-COM, you can switch between them when you carry out a servicing if you wish, just a case of changing a few numbers from what I remember.

An engine flush isn't part of the oil change service and inspection service which make up the variable service your car has just had. Ask the garage to explain why they haven't adhered to the specified service schedule for your car. It does sound to me like they might sell Wynn's Engine Flush (or similar) and automatically tag it on to every service like my local Peugeot dealer did. That dealership had a notice on the service reception desk advising customers that the product was used on every oil change and you paid for it by default unless you said no in advance.
