Why you need to use 504/507 oils in FSI/TSI/TDI engines!

[CraigR]

I've just got my car back from its 120,000km service, and was surprised to see the oil type changed from Liqui Moly 5w30 TOP TEC 4200 to Liqui Moly 10w60 GT1, because "its starting to get a few kilometers on it now" and have been running Stage 2 for most of its life.
Is it just me or is that extremely thick oil to be using. This car gets no track time at all.

Either is fine in a TSI.

Though it seems the 504/507 is preferred??

[Umai Naa!!]

VW spec them with 504/507, but 502/505 is ok to use, providing you stick to 15K service intervals.

The 5W40 502/505 oils do tend to help with oil consumption in some of the petrol engines.

all this vw504.00 is quite interesting.

all vw504.00 oil is also BMW-LL04 oil which BMW and MINI don't recommend using in their petrol engines due to the rather high sulphur in our fuel.

TBN in the vw504.00 and BMW-LL04 oils is around 5-6 only. VW502.00 / BMW-LL01 oils tend to be around 9 or even 11.2 (LM Special Tec LL 5W30).

anyway, perhaps VW knows something about Aus not so low in sulphur fuel that BMW doesn't know

Different emissions systems, and methods of achieving emissions targets.

Anyone have any thought surrounding this?

it does not look good to me for street use only.

especially that a typical golf mk6 r runs at 88-92 degrees C for street use in oil temp and a typical 5w30 oil has viscosity at 100 degrees of 11-12 cSt.

that specific LM 10w60 is rated at 24 cSt. that's twice the viscosity of typical wv504.00 oil.

These were my immediate feelings as well, and that the oil would be more stable at higher temperatures.

If it was a dedicated track car, I may consider using this oil. I didn't have any oil consumption issues just using the 5w30 top tec 4200. I think I topped up ~2L over 10,000kms.

A little confused after almost 20 pages haha!

B6 3C 2007 Passat Wagon 2.0TDI with DSG. 125,000kms.

15k service intervals preferred. What engine oil (and filter) should I use? Any notably better than others? Any cheaper oils that are still good to use for these?

Going back and replacing the oil with the correct viscosity/grade.
