Yeah, the injectors are pricey. The Titan is E85 compatible, but I am trying MMO in the gas, just to see how it works. I am not worried about warranty (long out of). I have run Techron and Regane before in the truck with no ill effects. I use Chevron/Texaco fuel when I can.
This weekend, I am going to put some in my OPE, as that E10, dissolves carburetor gaskets in about a year. Tried Techron one time and was told it is not advised for 2-stroke air cooled engines. Started using Opti-2 oil in my 2 cycles. Stuff seems okay, smells like seaweed, but little smoke. I am using it at 40:1 and not their 100:1 recommended ratio. It is a little less expensive than the Stihl Ultra syn. 2-cycle oil.
Thanks for the info.
