Hey TT,
My 2006 GTI is due it's 2nd service next month. My local dealer will let me supply my own oil - I am on time/distance but would like to use a premium fully synthetic oil as they put semi-synthetic in last time. What would you recommend ?
Strewth - are you sure it was semi-synthetic!

What does the previous invoice, or the servicing check sheet say?

I'm afraid that a semi-synthetic should never be used in a turbocharged engine, especially a turbo petrol. The absolute bare minium oil standard for the GTI on T&D services is VW 502.00 - which is a 5w40 fully synthetic (though some of the American originated oils, such as Valvoline, Amsoil and Mobil
claim to meet 502.00). Before anybody picks me up, and says - "ahhh, Mr TT, the GTI Tech Spec book also has 501.01". Well, yes, the bood does have it, but that is now an obsolete standard, therefore no longer valid.

Personally, though, I don't really like the 502.00 oils, for a number of reasons - it has a "summer" viscosity rating of 40, which is too high for modern engines designed to run on "thinner" oils, and secondly, 502.00 oils were developed long before "FSI" technology was introduced.
The only oils I'd recommend, for both LongLife
and Time and Distance for the GTI are the latest spec 504.00 oils, which include the Castrol Edge 5w30 (retail packaging, found at Halfrauds), or Castrol SLX Professional Powerflow LongLife III (trade packaging, identical to Edge 5w30, and now sold through all VAG dealers, or direct from Castrol). Other "quality" 504 oils include Elf Solaris LLX, Fuchs Titan GT1 LongLife III, Fuchs Titan GT1 Pro C-3, Motul Specific 504.00/507.00, Pentosin Pento Super Performance III, Shell Helix Ultra Extra, Total Quartz INEO 504-507.
Finally, there is Quantum lubes, which are the VAG "own brand" range. These are made by Castrol, and when you phone up Quantum TechSupport, they are in the same building as Castrol TechSupport. Their 504 oil is Quantum LongLife III, and is available in 1 litre (VW part no: ZGB 115 QLB 005 00, trade price £5.60, dunno retail), 5 litre (part no: ZGB 115 QLB 005 01, trade £27.50) and 20 litre (ZGB 115 QLB 005 02, trade £99.00 - which works out to £4.95 per litre

) packs.
And if you really want to push the boat out, and use "Volkswagen Original Teile" LongLife III oil, the 5 litre part no is "G 052 195 M4".
And finally, to be really anal, and have a litre bottle of "Volkswagen" branded oil for in the boot (its the same stuff as the Volkswagen Original Teile) - go for "GVW 052 195 M2" - retail £13.99, trade £7.70. BTW, is that retail cheaper than Halfrauds 1 litre bottles, as I know some petrol stations are sometimes £15.99 for a litre of LL3.

My current mileage is 10500.
Ohh, how old is it?
If its nearing 24 months or 2 years (from date of registration), then you will also need a two-year brake fluid change.
Other part numbers for the 2-year service:
- 06D 115 562 - for the oil filter kit (element and rubber seal), retail price £8.52
- N 908 132 02 - sump drain bolt (because the sealing washer is integral with the bolt!
), retail £1.08 - 1K0 819 644 B - pollen filter (standard), retail £6.99
- 1K2 819 653 B - pollen filter (enhanced, with activated charcoal - gets rid of smells too, hand for following stinky diesels), retail £9.38
Of the above pollen filters, obviously you can only use one or the other, and depending on where you live and/or drive will depend on which one you use. Both filter dust and pollen particles, but the one with activated charcoal also "neutralises" smells to. If you live or drive into a city, then I'd go for the activate charcoal one, whereas if you are in the scottish highlands, then the standard one will do.
HTH
