But they do use some type of special "mineral based 'break in' oil" rather than a synthentic oil.

That is very unlikely.Quote:

Edit:
Here are some posts mentioning the initial mineral based oil, from WhiteJames, WhiteJames#2, hmmm... now that I look at it, it seems to be mainly WhiteJames or people quoting WhiteJames...
I'm pretty sure it's a 504.00/507.00 oil they're using based on some posts on some oil analysis that have been performed on new cars.Quote:

Not only does 504/507 offer increased protection of after-treatment devices, it also protects the engine better due to stricter wear limits, not to mention the reduction of valve deposits - the core issue with FSI engines.
And with the cost of 504/507 oils these days (see first post for prices), why use anything else for these engines?
Is that with a petrol or diesel and what sort of fuel economy are you getting?Quote:

If its the same algorithm as used in the Euro spec cars then it will be based on their fuel sulphur levels and won't be valid for use in Australia.
When we get into the summer months I'll be interested to see how high the oil temperature gets. Having rented a couple of diesel Golfs in the UK my experience was that the diesels ran higher oil temperatures on the motorway than the petrol engines but were lower around town which I didn't understand.
"An oil’s kinematic viscosity is defined as its resistance to flow and shear" or simply, a measure of how thick or thin it is.
By using a viscosity calculator and values from the data sheets (assuming there are no typos), you can extrapolate these values for a given temperature. Obviously, these values only apply for brand-new, unused oils.
Data sheets:
Mobil 1 0W-40
Mobil 1 ESP Formula 5W-30
Shell Helix Ultra Extra 5W-30
Units are given as mm²/s (SI) or cSt (imperial). The lower the value, the thinner the oil.
Below 14°C, Mobil 1 ESP Formula 5W-30 starts to become thicker (viscosity @ 14°C = 258 mm²/s) than Mobil 1 0W-40 (viscosity @ 14°C = 257 mm²/s).
But it's not until -17°C that Shell Helix Ultra Extra 5W-30 starts to become thicker (viscosity @ -17°C = 2018 mm²/s) than Mobil 1 0W-40 (viscosity @ -17°C = 2015 mm²/s)
So, as long as the outside temperature is above -17°C (yes, minus 17) when starting the engine, it's the Shell oil that will flow the quickest out of the three. And I've actually seen it on the shelves at either Repco or Supercheap, though I forget which one.
But best of all, it's a 504/507 oil. :)
To my understanding 507 is specifically for the PD TDI's where it has to have both zero ash ( to prevent DPF blockage ) and high shear properties for the immense pressure the PD cam puts on the injectors. In a petrol car I'd figure they would indeed have a mineral based run in oil, which is optimal for piston ring seating, but in the diesel it just wasn't an option at run in time. I was pretty bummed!
So I've read the whole thread, some great info in here, cheers.
My 118TSI has done 5,600km in its first 6 months. It doesn't get much use during the week, often spending the entire week in the carport. When it does get a run on weekends, most of the time it does 25km in a stint. 1000 of its km's were done on a long drive for a holiday. Stop-start traffic for my car is practically non-existent.
It seems as though my car wont need an oil change until the 12 month service interval, is this correct? And then the best oil to get for me is the 504/507 type? Or more specifically, the Castrol SLX Professional Powerflow Longlife III 5W-30? Thanks.
15,000km or 12 months - whichever you hit first. The MFD should give you a warning about when the service is due (which you can also check manually - IIRC switch off ignition & press/hold the tripmeter reset button).Quote:

The brand isn't overly important as long as it's certified to the VW spec. Earlier in this thread (or another?) there's a big spiel about PIAO oils & cracked oils - make your judgement from that. I've had OEM fill (Shell or Fuchs AFAIK), Castrol & Valvoline in my engine. There's a bottle of Shell waiting to go in next & I wouldn't mind trying Mobil1 but they all seem to be doing the job.
