Many type 1 and type 2 owners use High Octane Gas [unleaded] in their cars in Australia.
Our "normal" unleaded gasoline is around 90-91 RON...
We use 98 RON high octane unleaded gasoline with no additives.
Some VW owners do use a lead replacement additive but VW engines do have hardened seats and valve guides.
I have thought of adding an additive... it can't hurt...
and some owners over here do use a fuel additive...
What gasoline do you use??
Do You use an additive [lead substitute]
