I filled this water bottle with one third oil and two thirds gas, shook, and it immediately became homogenous. So far no problems. Has anyone tried this?

Your fuel injectors might act funny with engine oil in fuel.
Besides, what does premixing with 4-stroke achieve? The oil injectors are already doing that. 2-stroke premix helps because it's designed to be burnt cleanly, and even then, no one has concrete evidence that it helps.

Yeah, premixing 4-stroke is generally a bad idea. Don't let the car sit for long, you want to keep it mixed in the gasoline while you burn through it, and not slowly separate until you hit a point where the fuel system only sees oil instead of gasoline. Fuel pump, fuel filter, fuel injectors... not to mention injecting straight oil if it gets that far.
I'm confident saying that 2-stroke is proven to work. The primary reason i say this is how the Grand Am RX-8s, prior to that the Grand Am RX-7s, and the entire Star Mazda / Formula Mazda series all premixed their fuel. I had a discussion with Speedsource crew about it briefly at Lime Rock in 2010(?) when I filled in on their over-the-wall crew on the #69. The other teams could all just fill up from the fuel provided at the track, but the RX-8s all had to bring in fuel with them, premixed with oil.
They couldn't run un-premixed without engine failure, and they definitely would have preferred to NOT go through all the hassle and cost of premixing and hauling fuel around for every race.

I don't recall any confirmation that they did not keep the OMP off hand (it's been several years), however I do not believe that they did, and I think the general consensus was that they didn't.

The few pictures I've seen of STAR engines, they didn't have OMP lines, but I've only seen two images of those engines, and they were in-car.

..l., You
I bought this car knowing what I was getting into. I took this car apart and troubleshot all the way from the maf to the omp nozzles. Then took out my renessis with a 2x4 and a rope, helped rebuild it then put it back in. I fixed almost every system in the car to some degree. And I didnt pay a ******* soul except for the rebuild. And I'm no mechanic. With the way i drive all that oil will be out of my tank today.
******* troll
..l., you
I do get your humor but im not that ***** who quits and blames others

the tank will be done before midnight.
I used to have injector and filter problems but used gummout complete fuels system cleaner and b12. Never had those issues again. oh i got my injectors cleaned at the rebuild too.
I used the castrol because there was no 2 stoke available that was jaso fc, only tw 3c or whatever. Actually the engine oil was recommended by the engine builder. Anyhow it looks like I will have to special order premix by the gallon. jaso fc is hard to find on a shelf around here

You could just buy a case of Idemitsu then, or order something else of your choice in bulk.
I buy a case of 12 quarts and it lasts me a year. This is with me daily driving my car.

Oh, and anyone who is premixing with conventional 4 stroke engine oil needs to stop, and go get some help.
