Dealer used Havoline 5W-40 12month service, 2.0 TSI

So you're saying that VW 502 oils may be more tolerant to sulphur than the 504s? I was considering switching to VW 504 and having frequent oil changes because of the sulphur. I figured 504 would be better than 502 in this instance once I kept the intervals short (6 months or 7500 miles)

Yes.
But given the short service intervals in your country (5000 mi. = 7500 km), perhaps it won't matter what you use.

But still, I would only use 504/507 if VW says you can use it in your country. And I definitely wouldn't bother if it's priced any higher or uncommon.

3rd service and 3rd time Camberwell VW (Bayford) have 5W-40 oil on the receipt

Looks like they're up to their old tricks again.

Ask if you can visually verify what oil they're using (if you can be bothered to check). Hopefully it's just a clerical error this time 'round (maybe).

I asked at Bayfords recently & was told they use Shell Helix (ultra extra 5W30?). Will have a look at my old receipts tonight...

Yeah, my receipts too state 5W40... Doesn't say what brand, tho.
