Just an update for those who are interested, I am about 600 ml into the 1 litre I bought, it has been used in my Galaxy which is on 50/50 ish bio dino our other Peugeot 1.6Hdi which is on dino and more recently my brother inlaws Audi 2.5tdi following what I can only say is amazing transformation to my Galaxy. I was beginning to think I would have to possibly replace or get overhauled the injectors as it was starting to sound really harsh and drive sluggish. I dosed at 3ml per litre for 70litres of fuel and 2ml per litre since then. The other cars have had 1 ml per litre added but only for the last couple of weeks or so so nothing to report on them yet.
The Galaxy is like a new car on steroids ! quicker to start, quieter at idle and drives like a dream. No need to floor it on fast roads just squeeze the throttle and she flies up to 100 in a breeze. Just bought 5 litres half given to my Bro inlaw for his Audi and the rest for my cars, it will go in the camper tomorrow and I shall take her for a drive to get it into the system but that wont get many miles for a couple of months yet.
How are others getting on ?
