I have a tank with 75:1 mix in it and just hooked it up to my motor to test it and the color of the gas going through my new clear fuel lines in the motor is the yellowish gas color...the two stroke oil I mixed in is blue...Shouldnt i be seeing blue in the fuel lines? Does the color fade away after a certain time?

Mine stays blue.

Has any other additive been dumped in the tank? Like Stabil, Ring-Free, etc.? And what fuel hose do you have between the tank and motor?

I asked about the hose because some black hose from auto parts stores will break down and discolor fuel.

mixed stabilizer and blue 2 stroke oil may change color.

If yellowish is the fuel color used, adding such a small blue 2 stroke oil ratio will probably do nothing changing fuel color.

Happy Boating
