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

You can run 502/505 in a petrol engine yes Using a non approved oil of the correct spec may not void your warranty but may upset VW if you have an engine claim.

I don't have 100% confirmation from VW Aus, but I believe the 502/505-spec 5W-40 oils are ok in the petrol engines.

Liqui Moly Toptec 4100 is 502/505-approved, as is Penrite HPR-5.

Pretty sure you're correct.

However the 502/505 isn't suitable for extended oil change intervals i.e. 25,000km. Not that you'd want to leave your 504/507 oil in there for that long anyway as allowed by VW in some countries.

As we have 12 month or 15,000k (whichever is first) oil changes it wouldnt be a problem here

Our Polo TSI manual specifies 502/505 or higher I just run them both on the 504/507 to save having two types hanging around.

Correct. 504/507 is meant to be good for 30K drain intervals, although I wouldn't tempt fate...

[Johnbu]

I'd rather use 502/505 and change every 15k than 504/507 every 30k.

I use 502/505 in 5w40 due to oil consumption issues using 5W30 in my MkV GTI.

In a petrol engine, that's fine.

But not in a diesel, where 504/507 is a must.

The problem in the USA with 504 is the low additive levels don't work well with the alcohol and sulphur in our gas. Dealers use 502 5w-40 and 10k intervals.

I don't trust any oil past 10k, the downside is too great.

Direct Injection can ruin most any oil....

It that graph from Bob the oil guy forum? I have near all my oil tests. I'd like to add mine.

Happy Days
