It has been brought to our attention by a few customers that some of their tablets are sticking together inside the tube?
We have a very difficult compound balance required between providing added performance and octane boost function, together with dissolvability. The octane boost as required in the petrol tabs is softer and doesn't like heat and so the tabs can fuse together. It doesn't effect the performance, it's just harder to get out of the tube.
This will likely not be a problem in the winter, but for our loyal customers who have experienced anything like this, please phone 0800 777 551 and we will happily replace any product.
