So I am wrong, the sticker on the bottle does make a difference? All the fuels I mentioned in my previous post are reputable fuel manufacturers, the difference between them is so insignificant as not to matter at all. I know because I have used them all. If you have had good results using a particular type of fuel, thats great. I have had good results using four different types of fuel and have come to the conclusion that if you go for a 'known' reputable brand such as the ones stocked in any LHS, you will be fine as long as the percentages are correct. As stated in my first reply to the original question.
