If you have a clogged injector, sure. I usually dump one in about 1-2 tanks before an oil change. If anything gets kicked into the fuel that combusts, it'll get caught in the oil and filter about to be replaced, instead of sitting there for another few thousands miles. Can't hurt the car.

Thanks, follow up questions. Is doing this the same as this service from the dealer (EFI SERVICE (FUEL INJECTION CLEANING SERVICE)). I just got the oil changed and they offered this at service time, so do you recommend holding off?

That's not how engines work at all.

No need to do this before an oil change

Engines don't go empty, they don't work like that. Your car has a gas tank which your engine uses to fuel it. You put it into that.
