To be a bit contrarian here:
The who subject of 2-stroke oils is a bit muddled, but there is basically a family of oils for water cooled engines (TC-W3), and a family of oils for air cooled engines, which often run at higher cylinder temperatures.
You Eska is an air cooled powerhead and as such should probably use an oil intended for air cooled engines. That said, you will not likely run the thing enough to ever notice any problems using TC-W3.
Out of curiosity I looked at the certification procedures (https://www.nmma.org/certification/oil/tc-w3) for TC-W3 oils and found this:
"The TC-W3® lubricity and preignition evaluations, which are performed on a Yamaha CE-50S [air cooled] motorcycle engine …."
More on that here: http://www.swri.org/3pubs/brochure/ae/p … ricity.pdf.
On top of all this, there are "synthetic" and "semi-synthetic" or "blend" oils. I have not seen any objective information on how much, and in what ways, this matters.
