Why not put 5w30 in it then same as the golf r runs ,which is hot hatch rather than a warm family hatch .

What a lot of a song and dance over oil for Road Cars in the UK not doing Track days or RWYB 1/4 miles.

Not highly tuned just maybe a stage 1 map.

Its just a 'puppet'

or just a car that might occasionally get booted to do more than half the speed it can for a short periods of time in a UK Climate.

Sorry, how do you know the car isn't doing track days or runway runs? The best I've done is a 13.7 @104mph in the dry at a private event near Oxford. I haven't done any track days in this car, but I fully intend to be at Brands or Cadwell before the year is out. That's in addition to wanting a Ring trip and to chase the 400bhp mark early next year.

With the absolute best will in the world, if I wanted someone to simply copy and paste some generic info from VW, with poorly edited syntax, I would have asked. Funnily enough, in searching old forum posts, I seem to recall you insisting you would "I would give the crappy 0w 20 FS IV a miss if i owned a TSI.  Any TSI." (19/01/2020), but here you are now suggesting to do it? Hmmmm.

I wasn't aware that before posting, I needed to list out my current uses, previous uses and future plans for the car, so that you can properly advise me. Frankly, just because you might have bumbled around in your Octavia, doesn't mean everyone does. You are normally very reliable and full of information in the months that I've been here - I'm not sure why it now seems to have changed.

Besides, even if my vRS was used for going to the shops and back, isn't a forum like Briskoda meant to be a judgment free environment, where people can discuss at length their questions/problems/thoughts, without fear of being slapped down by wildly incorrect sweeping statements?

@Mickvrs220 My thinking behind it is that if 5W-30 was such a good thing, everyone would suggest it. The fact that I'm getting recommendations of 0W-20, 0W-30 and 5W-30, is what's making me think twice. FWIW I'm not keen on 5W, but 0W-30 is a consideration.

I appreciate the input, but I'm perfectly capable of finding out what oil my car is recommended to have, in addition to what old vRS/GTI/R's run on.I wanted some specific, real world information about what oils owners have been using in a vRS 245 (or indeed any similar 2.0 TSI). I thought Briskoda would be the place to do this, but now I'm wondering if that's the case....

?

What oil do Police / Emergency Service VW Group / Skoda vehicles get used at services since 2018.

Petrol ones. vRS Octavia?

Do the Techs / Fitters or Mechanics follow VW Guidelines / Recommendations / Advice / Spec and use VW508 00 / 509 or do they use VW504 00 / 507 and invalidate the Manufacturers Warranty if there is one and the oil has not the green marker?

PS @OccyVRS

I would not use the crappy 0w 20 FS IV on a car i owned and a is a keeper. (Leased / Rented cars i could not care less)

But i make my own decisions on things like tuning , servicing, invalidating a warranty etc, i do not ask people that i do not know or care really what others do.

2020 the longevity of the TSI,s & VW508 00 oil used was still to be found out.

7-8 years now have passed since VW Group / Skoda went to using that to get WLTP & RDE results.

The engines are not going pop.

BMW,s were the engines that have really had issues over the years with Oil & EGR,s with Diesels.

Bro's can look at HTHS values for ACEA C5 (0W20 508.00/509.00) and ACEA C3 (0...5W30 504.00/507.00) oils.
This will drop idea what (could) be better for engine protection and what- for fuel economy.

In response to what I think you're saying in the first part, I would assume they use 0W-20.

To the second bit, yes, I would think it would invalidate the warranty (probably hence the green colour as an identifier), as it isn't what they reccommend.

So basically, the entire premise of this forum (and most of what you or I have said in it) is therefore irrelevant, if the knowledge and opinions of those on here are invalid as you don't care or don't know? You couldn't care less what others think, especially when they don't know you, but yet you give advice?

You aren't making sense!

Which is/was the entire premise of me asking the previous posters in this thread...

@OccyVRS Is it to be 0w 20 FS IV then after all that?

@Ootohere Honestly, I think so.

5W-30 is out as I'm not keen on the startups in winter. 0W-30 is a consideration, but I think I'll cross that bridge when I come to it. There's too many opinions, so for now I will just take VW on their word and keep it simple. At least until I've looked properly into the mechanical differences between the PFL EA888.3 and FL/GPF (beyond the oil pump).

It's done the last 40k miles on 0W-20 (I presume) so I only need it to do another 40-50k and that'll be that. I highly doubt using xW-20 over xW-30 will grenade the engine in the meantime and despite what I was orignially told, I've seen no real evidence otherwise.

If it ain't broke, don't fix it... at least for now.

0w 30 FS III is simply clever for good engine protection & longevity in a UK vehicle. (TSI)

When VW Group went VW508 00 / 509 00 that was not with all engines, there were TDI,s that stayed VW504 / 507. & Dealers used 0w 30 FS III.

Actually back in 2018 / 2019 there were Main Dealers still using that in cars at first services and 2nd, and parts department selling that to people with the cars delivered after the WLTP was introduced.

It certainly does seem to be the best of both worlds - which makes me wonder why they don't retrospectively reccommend it (but do in the EA888.4). The car is going in on Monday for the DSG/VAQ service, plus the annual and some other bits, so I'll have a good chat with the guy then.

An oil change is hardly an expensive job and is one that I can do myself in a few months once I've thought about it proplerly. I plan to get the car retuned towards the end of the year, so will likely change the oil then.

I read somewhere (I think it was GTI) that the dealers were told to use either 0W-20 or 5W-30, depending on what they felt like.

Just bought 6 litres of oil and a filter for mine £59 quid ,another 12 months has passed ,so car up ramps me on my back in the morning ,at least the vrs tsi is a very simple job .

I have a VW that I bought new in Oct 23.

VW recommend a C5 0W-20 oil is fitted.

You can also use a C3 5W-30 oil.

At the first service in Oct 24 the VW dealer fitted the C3 oil for me.

I keep my cars for a long time so the oil I chose is important to me.

Details I found were:-

VW 504 is a FS LL 5W 30 C3 oil and is better at reducing engine wear with a HT/HS viscosity of 3.5 cP than a C5 oil.

VW 508, VW 509 is a FS LL 0W 20 C5 oil has a HT/HS viscosity of 2.6- 2.9 cP. They can improve fuel economy by 1%.
Engines using this oil will suffer more engine wear than one using a C3 oil.

5W oil is still a flowing liquid at -30°C.

0W oil is still a flowing liquid at -35°C.

That seems a large difference, even if my understanding of centipoise is basic. Do you know what 5W-40 (Think VW 502) is at the hot end?

If it is a C3 oil then :-

ACEA C3

''Stable, stay-in-grade oil intended for use as catalyst compatible oil in vehicles with DPF and TWC in high performance car and light van diesel and petrol engines, with a minimum HTHS viscosity of 3.5mPa.s. These oils will increase the DPF and TWC life.''

As apposed to C5 :-

ACEA C5

''ACEA C5 oils are high performance, lower SAPS lubricants.
The primary goal of ACEA C5 oils is increased fuel economy in high performance petrol and diesel engines in passenger cars where advanced after-treatment systems such as Diesel Particulate Filters and Three Way Catalysts are used. HTHS viscosity must be in the range 2.6 to 2.9mPa.s (i.e. low) - typically SAE 0W-20 or 5W-20 and made with Group III base oils.''

---

The 5W-40 oil I use in the other three cars I run is a C3 VW 502 / 505 oil.

This will eventually go in my VW as well after it is three years old.

Thanks AG Falco

GM in the states are having some engine failures and their solution is :-

''After over 28,000 reported engine failures, GM is recommending thicker oil as a potential solution''

From a C5 to C3 oil but the API equivalent.

Thanks. AG Falco

Mmmmm. IIRC brands like Citroen are following suit.

I'm keen to do 0W-30, but want to make sure first they haven't fiddled with the engine to suit.

VRS245 DSG MY2020 (MK3.5) had it from new, nearing to 120k miles now. Mapped when it had less than 20k miles on it. Sat at more than 110mph in Germany for fair bit of miles, many occasions, raced a lot of cars, definitely done more than 50 launches and even more pulls... Silverstone and generally driven hard. Always on 0W20. Knock on wood, not had any issues whatsoever. Just regular servicing. If I feel like car is driven a bit harder than usual ill change oil after ~8k miles rather than ~10k miles. Personal preference Morris Multivis ECO VB 0W20
