Engine oil Mobil or Castrol

Just put mine in today at the owners manuals advice, 15,000 KM. Castrol 5w40

I prefer to use castrol gtx 20w-50 year round, but I'm being cheap lately. I've put over 120k on my 16v with this stuff so far

Dealer put Castrol SLX Professional LL03 5W30 in it.

Mobil 1 0W-40, never lost a drop of oil with 72,000 miles APR Stage 2

I'm using Edge 5w-30 too. Seems to do well in 1.8t... This is the dealer OE oil, if it's VW 504 it could be a problem with lowered additive levels for emissions protection, which does not work well with our fuel and engine tune in North America, although it is necessary to use in TDIs (VW 507). imo, Edge is the best of all words, a premium base oil, but with more additives than VW 504 or other low saps oil.

I use Castrol 10w-40 and it works great. I have no issues with the cam follower and also never have to add oil in between oil changes.

My cars running hell of alot smoother by the way with this oil.

my 2.0 has 280,000km and no leaks or burning at all. i never have to top up. i use 10w40 castrol even in the winter. i used 5w40 mobil 1 in my other golf last oil change and it works great too.

At around 60k the car really began consuming oil (1qt every 2000 miles or so). I used to use regular 5w-30 oil, and then switched to Pennzoil full synthetic 5w-30, which didn't help the problem at all, and maybe even made it worse. Finally, i switched to Mobil 1 0w-40 and all consumption has basically come to an end. I've not had to put a drop in it after 1500 miles and its at the same level as the last oil change.

5w40 + Canadian winter = NASTY valve tick upon start up. 5w30 cured this. I run 5w30 through the summer and its fine, even on the 30+ degree days. Now if I was in Mexico or southern Texas in the summer, maybe a 40 weight is a good choice.
