Megatech doesnt show a lot of products they sell for some reason's. It doesnt make a difference weather it's clear, blue, red pink purple, it's just the dye they use. O'Donell and other fuel are clear, I wouldnt worry about it to much. As for it being old if it is dont worry as long as it wasnt opened I wouldnt worry, just swirl it around to make sure the ingrident havent seperated in the container.

But to telll you the truth I wouldnt worry about it, but after you use up this fuel I would just stay with name brand fuel's. Then you know for sure.
