502 00 oil specification is 5w40 ?

[The1effect]

I am a bit confused about what type of oil should I get. On the book says 502 00, 504 00 a).  I am trying to buy castrol oil 5w40 and I get confusing results, some show on the back 505 00, 505 01 specifications and other have 502 00. I have been using Castol on all of my cars without any problems and I want to stick whit it, also I want to follow manufacturer specifications only.

There are a variety of Castrol oils approved to 502 00, in various SAE grades: 5W40,  5W30, 0W30 and 0W40. Take your pick.

If you want more than life than fixed servicing you'll need 504 00 spec though. create a login on erWin Skoda and you can freely download all the latest oil info.

5W40,  5W30, 0W30 and 0W40 have different viscosity at cold and optimal temperature. Why is such a big variation for this type engine? I’ll go for 5w40, hopefully is more suitable for UK weather. It seems that 502 00 is the same as 505 00

[Breezy_Pete]

Any would be fine, the differences can be small.

Correct temperatures for SAE oil viscosity testing inserted, underscore.

Personally I'd choose 0W40 as pumping up fastest on start-up (you can have the oil pressure light go out before a cold engine even fires with 0W oil) and the lowest viscosity drop-off rate with rising temperature. ( SAE J300 standard )

Skoda Citigo 1.0 MPI,s never came from the factory to the UK with a variable / flexible service interval / oil changes, only fixed i believe.

 

So VW502 00 was and is just fine.   5w 40 Full Synthetic.

VW 504 00 / 507 00 for Fixed or Variable servicing might well be what was filled at the factory or what gets used by many.

Or all the others listed.

Indeed. 

 But VW Group Techs were using 5w 40 FS or 5w 30 FS III     Quantum or Castrol in the main.

  & with VW UP!,s 1.0 TSI,s 5w 30 fs.

 

This was / is the VW Euro 5 engine chart from back when, and engine codes for service / oil regimes,  Fabia / Polo / Ibiza type cars.

Not Citigo though.

It's not like you to trust VW group techs to do the best for owners' engines!

[Ootohere]

No, but VW / Skoda making it confusing enough.

 

UK, no long life / variable / flexible service interval, oil changes.

So Oil to VW 502 00 is fine and 372 day / 9,400 mile intervals.

 

Or to VW504 00 / 507 00,  and still do Annual / Fixed oil & filter changes.   Or sooner. 

 (Unless someone decides they do not want to & go beyond Fixed Service Regime for oil & filter changes.)

You could also use 504 00 even if the car isn't set to variable servicing and service it  after a year and a half or two, according to usage patterns.

Just check the level regularly rather than relying on the (probably not fitted) level/temp sensor. 

The algorithm that supposedly tells you (on variable servicing) when the oil is worn out is probably pretty unreliable anyhow.
