How to dispose of Gas + Diesel mixed?

[Soupy]

I had a brain [censored] and added diesel to a half tank of gas in my mower. It's about 6 gallons of 50/50 gas + diesel. Luckily I have dual 6 gal tanks and can still use mower until I get the tank drained. Any Ideas of easiest way (but safe) to dispose of the mix? Will it hurt a car mixed 1 gal at a time with a full tank of fresh gas?

Thanks,
Ken

if its an old carb car with a big tank it should be ok.. dont try it with fuel injection

What kind of mower?

I'd throw it into my flathead, diluted with straight gas, and just burn it over time..

I'd do this as well.
I'd also consider mixing a small amount, like 2% at a time, to the fuel of any old car I might have. Be careful with this because diesel kills octane.
In a diesel like one of your old 123s, a similar amount of this mix in a full tank would also do no harm.
It would be a shame to just throw away fuel.
