My engine light came on earlier saying check oil but When I look online it’s saying 2 kinds of oil 

 

now I have a mk2 vrs 2.0 tsi petrol 2009 I’ve seen it says 5w 30 and also seen 10w 30 what do others use in there car ? 
 

also I’m told the octavia’s do use quite a bit of oil is this true ?

Those are not, of themselves, useful oil descriptions. If you have a manual, it should state one, or more, VAG specifications.

 

You want an oil that meets the appropriate VAG spec.

 

If that fails, a site like 'Opie oils' (https://www.opieoils.co.uk) will let you  search for oils suitable for your car registration. 

 

You are likely to find that there are two types (for fixed servicing intervals and variable) and for Diesel and for Petrol, although most oils meet both the Petrol and Diesel specifications.

 

I think you are most likely to be on 504 00 or 507 00 specs, but your manual should tell you.

Well, not generally. My caxa-engined one hardly uses any, but other  engines and abused examples may well be worse.
