Running Rich or Turbo going?

[lukemk5gti]

200ml every 6 months is a lot.

I put 100ml in every 8 months because the nearside rear corner of my head gasket has a slight weep on the outer coolant jacket.  Common on the K04 engines apparently.

My volume was a total guess, I used more doing long 600km return trips across the country.

Don't need to top up as much with city driving.
