By "quality" do you mean 98 octane fuel? Also, I have a 50ml bottle of Redex but it doesn't have any dosage instructions on it. Does anyone know if this would be too much for an 18-lire tank?
Many Thanks.

I've been using Silkolene Pro FST in the last few tankfuls.

First tried 200ml - didn't quite do it.
300ml- great.
250ml- pretty good.

So- 250ml of FST in the tank just before you fill- seems to do the trick and up it if the weather's much colder. 300ml got rid of all knocking during warm up.

For me that means 1 bottle of FST a month on average if I were to use it every tankful. I reckon as it gets warmer it could be less often, or smaller dosage.
