Yes. You may not get the same performance (horsepower) as you would with premium gas, but modern cars can run fine on any grade of unleaded gas.
It depends on the model and the specification of what you have. A car filled with diesel that is supposed to have regular unleaded is not going to run at all.

Mercedes all the way
unleaded regular in a 300e Mercedes? My Mercedes mechanic says yes as long as you don't hear pinging. Usually if your car is tuned, not pulling or carrying a load, no mountains, not a lot of stop and go traffic, and ac off. try mid grade if you hear pinging with regular, and stick with premium if that does not work.

You can but you shouldn't use supreme unless the car is specified for supreme and if it is you shouldn't put regular in it.
In general unleaded in diesel is worse but it depends on how much unleaded went into how much diesel.
