Motomaster used to use Shell but several years ago switched to Citgo. I cannot remember where I read that but even the bottles were the citgo/mystic shape.
Wow! I ran Opti-2 for close to a decade in commercial cutoff saw applications. Great stuff, but it always seemed to have a negative affect on power if I ran it that rich. I usually ran it ~75:1 and my saws always seemed to outlast the guys using Echo or Stihl 50:1 mix.I've been mixing Opti-2 at 44:1, 1 gallon at a time. Have some Amsoil Dominator I'll try once I finish the Opti-2.
I haven't noticed any issues with power. I do like that there is almost no smoke with the Opti-2. I've run pretty much all the 2-stroke oils out there, Husqvarna, Stihl, Echo, etc.Wow!

Update: I recently purchased a Ryobi One+ battery powered blower and string trimmer. Never going back to 2-cycle mix again. These tools work great.I used to use regular pump gas, E10 87 octane, and mix a gallon of 40:1. It would take a long time to use up a gallon.
Now I buy the True Fuel 40:1. One quart can lasts me two years in the leaf blower to clear the walks of grass clippings. The few extra dollars spent is worth it to me to not hassle with it.
The packets I bought before were 1.3 ounces so were 100:1. I usually mixed them with 3/4 of a gallon.I packet of Opti-2 and a gallon of gas
Using a mix calculator it looks like about 70:1
The packet I use is 1.8 ozThe packets I bought before were 1.3 ounces so were 100:1. I usually mixed them with 3/4 of a gallon.

I'm going to burn the rest of my 2-cycle mix in the mower and never look back.
You must have a nice smelling yard.91 octane EO with Klotz R50 mixed at 50:1. Works great in my chainsaws, blowers, and trimmers.
