Hi,

I have Superb III, year 2020, 2.0TSI DNUA - 272ps. However, not long ago I moved to stage 1 tune by Revo ( the car is now making around 350ps ). Its been recommended to me to move to 5W40, even though the engine "wants" VW 504.00/507.00 specification.

Does anyone have any experience with this?

So far Ive been running Castrol 5W30 LL with no issues, only a small oil consumption based on my style of driving ( circa 650ml per 8500km ).

Thanks for any help

If it was your tuner then they should be taking responsibility for that advice; if it’s someone else, then I would run it past Revo and see what they say.

There’s a fair amount on t’internet that classically divides opinion - best get it from the tuner themselves.

All the above advice is applicable - as usual!

But it is a minefield ... it is not difficult to find a xW40 oil that will meet the VW504/507 spec, it is impossible. There are none ... only 0W-30 and 5W-30, in both "normal" and "long life" variantes.

There are a number of topics debating the subject, mine theory is that VW geared the engines and the specs towards LL oils that are of lower viscosity and thus diminish emissions and consumption ... and probably fitted a "lighter oil pump" i suspect.

The owners manual states:

Petrol engines: VW 504 00, VW 502 00, VW 508 00, ACEA A3/ACEA B4 or

API SN, (API SM)

Keep in mind VW504/507 is the manufacturer approval, but not the lubricant specification, which is the ACEA A3/ACEA B4 or C3 for Diesel ..... a good oil matching that should be equivalent. You also have to cross-check the "approvals" for example, because an oil corresponding to 504/507 like the Edge 0W-30 or the Shell Helix Ultra are both "approved" 504/507 but then are C3 which is NOT listed in the OM as the spec for petrol engines ... since are NOT A3/B4.

Yo should also cross-check with relevant other approvals, like equivalent MB 229.51/229.52 or Porsche C30, because it is not a given that the same oil manufacturer "offered" to all car manufacturers their oil for "approval", of they might not be in bed with them to promote a specific product/brand! Like see the French with their Elf/Total, Fiat with Agip and so on.

If all this has been enough to give you a headache, you're welcome!

I have never been so confused by something so simple in an industry that has managed to complicate even the simpler aspects of their basics!

For now and the cold season, I found a good offer for OE VW LL in 0W-30 and will put this, then when the hotter period comes will think again ...

Probably the Fuchs Titan SuperSyn in 0W-40, which is not 504/507 but it is A3/B4

Here are the specs to compare with the OE oils, I would do it now but the dog is dragging me to go take her for a walk 😁

Since I dont really have that much time to research stuff, I went with the spec - RAVENOL VMP SAE 5W-30

& for fixed Service Regime or sooner oil & filter changes VW502 00 spec is perfectly fine. 5w 40 FS not Long Life.

The unknown variable is stage of tuning.

RacingLine don’t seem to advise different oil grades post remap so opinion must be divided in general, but I still maintain it would ultimately be down to Revo if they have a strong opinion on it.

You can always change it again whenever you wanted anyway.

And is not a small "unknown" ... so it makes sense to stick to the spec, but I would also consult on what basis they advice the change, after the tuning.

Revo advice for mine at stage 2 was genuine plugs and OEM oil. With the only restriction being that they are both changed more frequently.

I normally run Castrol LL at 5w-30.

None available when I needed it, so have as of yesterday, changed the oil with Castrol LL 0w-30.

This leaves my personal intervals at 6 months instead of 12, and about 5k miles between changes.

DSG also running Revo software, and I had already dropped the factory interval for oil change down to every 3 yrs instead of 80k.

DSG serviced yesterday as well for the second time at 52k with genuine bungs, filters and oil from TPS.

Good to know - you can't go wrong with changing oil more frequently tbh. I've never bothered as we only do about 6/7k a year (March 2021 so over 4.5 years old and just below 30k miles) but given the servicing is done in Sept and the MOT in March, I'll start dialling in an oil change at MOT as well.

Oil change even at the lower mileage always makes a noticeable difference.

DSG oil was changed at something like 26-27k the first time and then yesterday again at 52k.

DSG oil was slightly brown but not bad.

Oil change has made a very noticeable difference in smoothness and changes even at the low service interval.

It’s due plugs again next year and I think I’ll replace all the coils as a precautionary measure to avoid even a slight miss, at the same time.

Can’t do any harm, except to my wallet.

This might be worth it then if plugs are on the radar - Black Friday Spark Plug deal

Yeah my DSG isn't the buttery smoothest. Always had a gentle thump on 3rd to 4th manually (and sometimes 5th to 6th so seems common on the shaft) so I'll probably prompt for this at MOT in march in that case. Given there are absolutely no intentions to move this car on any time on the horizon, I'll benefit from all preventive maintenance so any hit to the wallet now is a reduction from a 4-figure repair bill later in the worst case.

dont use 5w40, it is old A3/B4 oil, since your car have particulate filter, if you didnt remove it, it demand low saps oil. in manual says 5W-30, 0W-30 / VW 504 00.

if you live in colder area then 0w30, if you live in warmer area 5w30.

in all other cases use 0w30, shorten intervals, 5000 miles, and your car will be happy.

nevemind if it would consume more oil, those modern oils are superb.

mine tuner also with revo map on 1.5 tsi 150 ks / 250 Nm, remaped to 190 ks / 290 Nm said me use 5w40.

nonsense, i am using shell helix ultra AV-L 0w30 from beginning.

all great, only consumtion of gasoline and oil increases, but that is normal.

that chip tuners and remappers are electronic and informatic technitians, not car mechanics or mechanical engineers..

They are on my radar ... I am at 60k km time for them. Would this be ok for mine (our) engine type?

The ones in the link is a typical misunderstanding - understands my car is a DNFE engine but proceeds to suggest lots of ea888.3 parts.

Having said that I think the plugs are the same between ea888.3 and ea888.4 so these should be correct.

There is a 5W-40 which is a C3 low saps fully synthetic oil.

I use it on three of my cars which is VW 502 VW505 graded.

Thanks. AG Falco

Sure castrol magnetec and some total Ineo are mid saps.

People often use them for TDI 1.9 Pumpe duse.

But i dont know. 5W40 dont flow fast enough when engine is cold.

What is the difference between 5W 40 and 5W 30 when the engine is cold?

Thanks. AG Falco

I seem to remember a chart in the 'bob is the oil guy' forum, but now I cannot find it ... very negigible differences in cst ... the difference is "up high" when the temp increases ...

I was browsing around also in parts catalogue and no I cannot find confirmation of this, so I guess will have to the the typical "pull it out and see" method 🙃

EA888.3 - NGK ILFER7C8EG

EA888.4 - NGK SILFER8C7ES

Autodoc also have SILFER8D7ES. There is a decode chart for each of the letters so I’m not sure what the difference is but you have to look up the Golf Mk8 R or Audi S3 8Y to get the equivalent DNF engine (otherwise it just assumes EA888.3 engine 🙄)

Always complicated, eh? 🙃

Tell me about it! No-one seems to acknowledge the difference between the 3 engine codes/2 different engines.

I spent so long trying to be sure the Bosch versions I finally got were right let alone trying to look at uprated versions with a cooler temp etc.

Wait until you find out that your Haldex is Gen6 and not Gen5 like everyone thinks…(part number starts 5WA not 0CQ)

Noooo .... it is next on my list 🙃☠️

Nothing wrong with servicing; I think it’s largely mechanically the same. But I looked at tuning it for more RWD and found that no-one supports it yet.
