I was in the Car Trade for 21 years as a small retailer. I have sold the Duckhams Q then they went over to the Hypergrade which i saw a big drop in sales and people went over to GTX BUT we bought palets of the old Duckhams Q so we had years of supply and we were the only place in the County that had the original Duckhams Q and we use to have people coming in from all over the Country just to buy it Even Duckhams wanted it and offered us one for one swap for Hypergrade but we declined.Great product great oil but the Hypergrade was not liked THEN Halfords and started selling it cheaper than we could buy it so small retailers started to sell Comma oils and Duckhams was pushed to the back of the queue., Shame...
