16 TSI 2.0Litre Turbo. 45,000 miles
Check engine light, leaking intake manifold replaced along with various gaskets.
Said engine had a lot of carbon build up and said to use Top Tier Gas. Got it. understood.

Then the service manager said I don't care what the filler door says or the manual, VW
came to there shop and told them to recommend running 87 Octane it will keep the valves cleaner Thing is I can't
find anything online including VW to confirm this.

I know this guy he has been a VW mechanic a long time so i'm conflicted and confused.
