Wrong gas in lawnmower ?
Hi all,
I have a 17 hp Crafstmen riding lawn tractor. The other day, my son cut the lawn when I wasn't home and accidentaly put some of the 40:1 gas/oil mixture I use for the weedeater into the gas tank. He finished cutting the grass with it and din't have any issues. I haven't used it since but there is still some in the tank. Should I drain and refill or just fill with more reg. gas to dilute. Hopefully this will not cuase any issues. Thx

Mixed gas won't cause you any real issues. It'll smoke a bit, but that is about it.
If there is less then half a tank in there, I'd simply top it up with regular (unmixed) fuel and go.

I'd just fill up the tank with regular straight gas. Aside from smoking a little the plugs might foul a bit but if it's running fine I would not even bother pulling them to check.
Making the reverse mistake would be very bad. Putting straight gas with no oil into a machine that needs the gas/oil blend can quickly destroy an engine. If that ever happens I would immediately drain the tank, carb. and fuel lines and fill with the proper gas oil mix.

Mike and Dane share my thought process - mostly full tank, drain it but if the tank is mostly used already I would just top it off with the proper gas and move on.
