I put some 2 stroke into our 2008 Hyundai sonata. Seems to like it.
Last time I tested 2 stroke oil was in a car that couldn't tell the difference between ethanol free and e10. It saw an improvement but not enough to cover the cost of the 2-stroke.
I dumped some in in the Hyundai and now it's turning 29 to 30 mpg on the highway at 75mph with the A/C. Last time I saw 30mpg on the highway at 75mph was with no A/C and a strong tail wind. I used a lot, somewhere around a 250:1 mix.

Presumably it would take more latent heat from the intake air in order to vaporize the same volume of fuel with 2-stroke oil added to it, so you'd get more miles per gallon based on that. On a sidenote, did you notice any spark plug fouling due to carbon deposits from unburnt oil?

Well it's doing something. Filled it up and ran 3/4 of a tsnk and the oil went from looking like normal 3,000 miles old oil to getting nasty quick.
Crud from the piston rings and upper piston area maybe?
I hit it hard probably running 250 to 1, but I'm cutting get it back to more like 400 to 1 or less. And switching to cheaper marine 2 stroke for water cooled engines.

Last time I saw the prices for 2-stroke oils, the only ones I could find easily and relatively cheap were recommended for air-cooled engines. Marine oils tend to become more expensive too, just like any other boat supplies... |

Running around 250:1 with ethanol free gas I did get some spark knock today at wide open throttle, never heard it before on this car. I'll immediately fill it up with more ethanol free RUG and cut the mix to at least 400:1.

Back when I was considering home made bio diesel, someone mentioned an ounce of acetone per 20 gallons of gas modified the fuel droplets surface tension to be smaller but only on closed to atmosphere storage systems and while the acetone didn't evaporate.

Wouldn't ethanol be supposed to "fix" the octane rating?
