Short answer is no. The use of pure E85 in standard gasoline car engines will void the manufacturer's warranty, may disrupt oxygenation control in fuel-injected cars, and may result in power loss. It may also interfere with proper operation of the catalytic converter. E85 can also cause engine damage, since prolonged exposure to high concentrations of ethanol may corrode metal and rubber parts in older engines (pre-1988) designed primarily for gasoline. Post-1988 fuel-injected cars are designed to accept E10 fuel, and may be tolerant of higher concentrations of ethanol to varying degrees, usually up to at least 20%. Check your owner's manual to see exactly what the fuel requirments are for your vehicle.

E85 gas in a nonE85 vehicle by mistake is it safe to operate vehicle?

Depending on what year the vehicle is, likely no problems at all. Most cars/trucks built from the early 80's up are compatible with fuels that contain ethanol. Ethanol is NOT as corrosive or acidic as people will likely lead you to believe. Methanol is to certain materials, most of which very rarely show up in a fuel injection system. But it does not mean the vehicle is designed to run on ethanol. But if a later model vehicle 50% E85 or even more % should not hurt things, but I would recommend getting more gas in the tank ASAP. Do NOT apply heavy throttle, as ethanol runs much leaner than gasoline and could potentially cause damage at those conditions. But for a modern computer controlled fuel injected vehicle, running a fair % of E85 will cause no problems other than some drivability issues as the PCM learns the leaner mixture and compensates for it. But at heavy throttle, the PCM often is running on fixed data tables and the leaner mixtures if lean enough, could damage a valve or piston. Flex Fuel vehicles have sensors to determine the % of Ethanol in the mix, (either virtual sensors or actual physical sensors) and the compensation or learning is seamless.

we'll it does happen very often it would be very bad if it was the other way around gas fuel on to a diesel vehicle. but in you case most of the time depending on the volume of diesel mixed it only smokes out your exhaust pipe.if tho volume mix was higher of diesel your vehicle would have fouled the spark plugs and would not fire there fore you would have to take your gas tank out and fully drain or reclaim the mixed fuel ,..if you vehicle is still running just ran till fuel becomes empty or vise-verse,..I've had vehicle newer than 2000 that are mitipoint fuel injection and computer puts vehicle to run in safe mode ,..with this issue no option there is but to drain fuel tank and add fresh fuel hope this helps!!
