I think you are fine doing this. I've done similar many times and have never had an issue running multiple chainsaws and a leafblower with the mix. My current concoction fueling my equipment is a mix of e0 90 oct with Husqvarna oil, Trufuel, and RedArmor 50:1, with an approx. 45:1 ratio overall. Works great.
However, I would recommend using only e0 in OPE, especially if the gas is not going to be used in the near future or sit in the equipment for any long period of time
