I try to not mix fuels from two different bottles, even if they are the same brand. If you have a bit of fuel left in a jug and it has any moisture or debris in it the other jug of fuel will be ruined when you mix them together. Just fly the last bit of fuel out of the jug before opening the new jug of fuel. There really isn't any benefit from mixing them anyway.

I was just trying to compensate for the 16% oil content, which my manual says is not enough (says AT LEAST 18%). It's the only LHS around, so I wanted to support him and try to make it work (and not wait for shipping). Guess I'll give Tower a call.
