In the UK at least Shell have introduced a new regular petrol & diesel they call Fuelsave this takes the place of the normal stuff. They claim it can save you up to 1 litre of fuel per tankful used.
I am now using it in my 1.6 petrol and it seems to be making a difference but its too early to say if this is consistent anyone else tried it yet?
