Default Combining glow fuels

I have a few nearly empty bottles of glow fuel sitting around. Should Istay away from combining them together?They may or may not be the same nitro percentages. My fear is a stalled engine mid-flight.

Thoughts?

If the fuel has always been sealed tight and out of the sunlight it should be fine. Mixing equal parts of 10% and 15% will give you 12.5% nitro. and so on

Exactly right. If it's clean, fresh fuel, go ahead and mix it. Be sure to readjust the carb needles before you fly.

The guys are basically right if the fuel is clean and fairly fresh. Even better would be mix them all together and then mix that combo with an equal volume of brand new fuel, get your needles adjusted and go fly.

Thanks guys. I figured as such, just wanted to make sure it did not "seperate"if left to settle for a week or two, then not have the needle set properly for one of the mixes and have a dead stick. I would shake it anyways before filling and flight.

Thanks again.

When I have a half gallon of fuel left, then I go to the LHS to buy one more, I always use 15%, when there is less than a half of a gallon in the bottle that I use carry in my tool box, then I open the new bottle and pour more fuel in it. That way I have relatively fresh fuel always in my tool box. When using big glow engines I better make a stop at the LHS, before going to the field.
Sometimes I have to adjust the needle valves, but I think that the fuel is not the only reason, here the weather is very different from one month to other, even a click or two is an adjustment and there are more than one reason for those adjustments.
