no, a small amount of gas will not hurt a diesel motor. in fact ,before all the diesel supplements were available, truckers would use some gas in their fuel in the winter to remove moisture,and to stop the fuel gelling. also used sometimes to boost power a little. gasoline also cleans injectors
.Mixing a small amount of oil in the diesel fuel will not hurt a motor. The motor will run rough and produce black smoke.
Diesel fuel injector cleaner will not hurt your unleaded gas motor. The diesel fuel injector cleaner is basically the same as your unleaded injector cleaner.
No as long as it is a small amount
I believe people who habitually fished on small ponds would be sensible enough to use an electric troller motor or even oars.
YES
NO
Depends how much, If it is less than 20% of the total fuel capacity then fill it up with gas and run it. It will smoke quite a bit but should be OK. Diesel has more lubricity than gas which should not hurt the fuel system. You might want to syphon out the diesel mixture best you can if it won't run any good. Running it should not hurt the injectors or to much just don't work the engine to hard as it may operate at a higher temperature. If it does run hotter then stop and you will have to clean out the diesel somehow. Running it to hot could result in engine damage.
Food colouring is full of sugar you can use it but a small amount won't hurt
It depends on how hard you beat your dog with the slat. If you misspelled Salt, small amount are O.K.
as long as it is a small amount you will be okay. but if the trans fluid is pink or discolerd now then you should change fluid and filter asap
Not sure what a small amount of water is, a drop? A couple ounces? A pint? Anything more than a couple drops in the crankcase wouldn't be healthy for the engine.
Yes.
