I've mixed about 2 gal of diesel with 13 gal of gas in a ((carbureted engine)) with so so results in 40F temps.
It had a random miss under load, got better as it heated up, but didn't quite go away.
Had it been 55F overnight or more (my overnight lows are rarely over that) I think it would have ran better.
In my opinion I think a carbureted gas engine would run on pure diesel if everything was heated up before it hit the carb. As well as the engine up to temp.

It was a 300-6 with the 8 to 1 compression.
The EFI version is 8.8 to 1
The original 1965/1972~ version is 8.9 to 1
The other thing I'll note is there was no 10% ethanol in the gas.

I think you would have far better luck running biodiesel in a carbureted engine then filtered fry oil. And doing it in a fuel injected gas engine Is going to be very poor results.
