First conditional: if + present simple, will/can/may + base verb for a real future possibility: If we leave early, we will avoid the heat. Second conditional: if + past simple, would + base verb for an imagined or unlikely situation: If I owned a boat, I would use it responsibly. Were is a standard hypothetical form with all persons; was is also common with I/he/she in informal usage. Do not normally use will in the if-clause.
